In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate to implement embodiments of the application in a sequence other than those illustrated or described herein. Furthermore, in the present specification and claims, "and/or" means at least one of the connected objects, and the character "/" generally means a relationship in which the associated object is an "or" before and after.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
Distributed microservices are one design way to combine distributed systems and microservice architectures. Under this architecture, a large system is split into multiple small, independently running micro-services, which may be distributed across different computers or physical locations. At present, a maintenance stopping mode is generally adopted for updating distributed micro-services, and the maintenance stopping mode comprises a series of operations of stopping service, downloading, modifying, testing, packaging, redeploying, uploading and the like on source codes.
However, the operation flow of repairing through stopping service is complicated, and a great deal of time and labor are consumed, so that the repairing, testing and updating equivalent rate of the system in the operation and maintenance stage is reduced, and the user experience is further affected.
In view of this, the embodiment of the present application provides a method for updating distributed micro services, by sensing a change of a configuration file of a configuration center, acquiring the changed configuration file from the configuration center when the configuration file of the configuration center is monitored, analyzing the configuration file by using a file analyzer corresponding to a file type of the configuration file to obtain an update parameter, loading the update parameter to the distributed micro service, and updating the distributed micro service, without operations such as stopping service, going offline, modifying a source code file, and the like, and also implementing dynamic update during service operation.
Specifically, referring to fig. 1, a flowchart of a method for updating a distributed microservice according to an embodiment of the present application is shown. As shown in fig. 1, a method for updating a distributed micro service according to an embodiment of the present application may include the following steps:
S102, monitoring the configuration files of the configuration center through the monitors of the distributed micro-service.
The distributed micro-service is an architecture mode, and by splitting a large application program into a plurality of small and autonomous service units, each service unit can be independently deployed, expanded and managed, and is focused on executing specific business functions and interacting with other micro-services through a network communication protocol.
Where a listener is a mechanism for monitoring and responding to events, changes, or messages, either internal or external to the system.
Wherein the configuration center is a service or tool for centrally managing configuration information. In distributed microservices, it is often necessary to configure a series of parameters, such as database connection information, log levels, cache configuration, etc., which are centrally stored, managed by a configuration center, and provide a mechanism for the distributed microservices to obtain these parameters from the configuration center. In the embodiment of the application, the configuration center can be Nacos distributed service discovery and configuration management system or Consul distributed service discovery and management system. Wherein Nacos is an open-source platform for service discovery, configuration management, and service management, providing a simple and efficient way to perform dynamic service discovery, service configuration, and service metadata management; consul is an open-source distributed service grid solution that provides powerful service discovery and configuration management tools that help build reliable, resilient distributed systems. Specifically, an appropriate configuration center may be selected according to the requirement of the project, which is not particularly limited in the embodiment of the present application.
According to the embodiment of the application, the configuration files of the configuration center are monitored through the monitor of the distributed micro service, so that the change of the configuration files of the configuration center is perceived in real time, and further the distributed micro service is updated thermally according to the changed configuration files in the configuration center. Specifically, the following steps or examples will be explained.
As another alternative embodiment, before S102, the method may further include the following steps: acquiring a server address of a configuration center;
connecting a registry of the configuration center based on the server address;
The listeners of the distributed microservice are registered to a registry of the configuration center.
The server address of the configuration center refers to a network address or a domain name of the configuration center, such as an IP address, and is used to identify or locate the position of the configuration center, so that the distributed micro service can establish a connection with the configuration center and perform communication.
The registry of the configuration center records information of each micro service, and the information comprises configuration files for configuring each micro service. The server address of the configuration center is connected to the registry of the configuration center, and relevant information is obtained by accessing the registry.
According to the embodiment of the application, the configuration files for configuring the distributed micro-services are stored in the configuration center, the configuration center is used for uniformly managing and adjusting the configuration of the system, a plurality of services can simultaneously load the configuration files of the configuration center, the uniformity of the configuration of each service is realized, only one configuration file needs to be modified, each micro-service obtains the changed configuration file from the configuration center for updating, one configuration file does not need to be configured for different micro-services independently, and the shutdown modification is not needed for each micro-service, so that the thermal updating of each micro-service in the distributed system is realized. The configuration file for configuring the distributed micro-service may be in xml format or other format, for example: yaml, html, text, or the like, or may be stored in the configuration center in the form of key value pairs.
Specifically, as another alternative embodiment, in the case where the existing form of the configuration file of the configuration center includes the key value pair, the following steps may be further included before S102: acquiring a configuration file for configuring the distributed micro-service;
based on a preset coding mode, coding the configuration file to obtain a character string corresponding to the configuration file;
And storing the file identification of the configuration file and the character string in the form of key value pairs to a configuration center, wherein the character string is a value of the key value pairs, and the file identification of the configuration file is a key of the key value pairs.
The configuration file is encoded, so that the system is prevented from being attacked due to data leakage in the configuration file, the safety and stability of the system are improved, meanwhile, whether the configuration file is changed or not can be monitored more conveniently by encoding the configuration file into character strings, and if the configuration file is changed, the obtained character strings are different from the character strings corresponding to the configuration file before the history change, and the configuration file is judged to be changed. Common coding schemes, for example: base64 coding, hex coding, UTF-8 (Unicode Transformation Format-8-bit), and so on. The Base64 codes are coded by using printable character sets, are easier to process and transmit, have compactness and higher security, are widely used, have libraries or functions for providing corresponding codes and decoding in most programming languages and applications, are easier to exchange data between different systems and platforms, and are very important as a lossless coding mode for application scenes requiring accurate restoration of original data. Based on the above, the embodiment of the application preferentially adopts Base64 coding to code the configuration file.
As an alternative, if a higher security level storage mode is considered, an encryption algorithm such as: symmetric encryption algorithms AES (Advanced Encryption Standard) and AES (Advanced Encryption Standard), asymmetric encryption algorithms RSA (Rivest-Shamir-Adleman) and ECC (Elliptic Curve Cryptography), and the like encrypt the configuration files, and store the encrypted configuration files in a configuration center for each micro-service to acquire. Specifically, the configuration may be set according to actual needs, and the embodiment of the present application is not particularly limited thereto.
Where file identification refers to information or tags that are used to uniquely identify or identify a configuration file. May be a file name or other parameter that can be used to uniquely identify a configuration file.
The key value pair is a data storage and expression mode, and consists of a key and a value. The key is an identifier or name of the target storage data for uniquely identifying the target storage data. The value is the target storage data. The content data of the configuration file is used as the value of the key value pair, and the file identification of the configuration file is used as the key of the key value pair, so that unified management and adjustment of the configuration file by the configuration center are realized, and the configuration file is conveniently searched and compared to find whether the configuration file is updated and changed.
The embodiment of the application obtains the corresponding character string by coding the configuration file for configuring the distributed micro-service, stores the corresponding character string in the configuration center in the form of key value pairs, and is convenient for searching and comparing the configuration file in the configuration center according to the key value pairs while ensuring the safety of data in the configuration file so as to find out whether the configuration file of the configuration center is updated and changed.
Specifically, as an alternative embodiment, in a case where the existing form of the configuration file of the configuration center includes a key value pair, the step S102 may include the following steps: acquiring the latest key value pair from a configuration center through the monitor;
acquiring a history key value pair from a configuration center, wherein the key of the history key value pair is the same as the key of the latest key value pair;
Comparing the value of the latest key value pair with the value of the historical key value pair;
based on the comparison result, it is determined whether a change has occurred in the configuration file of the configuration center.
The history key value pair is obtained by storing and configuring the center in the form of key value pair based on the configuration file before modification.
It should be understood that when the configuration file is stored in the configuration center in the form of a key value pair, a corresponding configuration item is formed in a registry of the configuration center, the distributed micro service senses the newly added configuration item through the monitor, finds a history key value pair identical to a key of the latest key value pair according to the key value pair corresponding to the newly added configuration item, namely the latest key value pair, and judges whether the configuration file of the configuration center is changed by comparing the value of the latest key value pair with the value of the history key value pair. As an alternative way, if the value of the latest key value pair is the same as the value of the historical key value pair, determining that the configuration file of the configuration center is not changed; if the value of the latest key value pair is different from the value of the historical key value pair, the configuration file of the configuration center is determined to be changed.
As an alternative implementation manner, in the case of performing an encoding operation on a configuration file for configuring a distributed micro service to obtain a corresponding character string, and storing the corresponding character string as a value of a key value pair in a configuration center in the form of a key value, the configuration file of the configuration center may be determined not to be changed by comparing the character string corresponding to the value of the latest key value pair with the character string corresponding to the value of the historical key value pair if the character strings are the same; if the character strings are different, the configuration file of the configuration center is determined to be changed.
As an alternative, the value of the latest key value pair is compared with the value of the history key value pair, and the comparison result may include changed data, newly added data, missing data, and the like. If the comparison result has changed data, or newly added data, or missing data, the configuration file of the configuration center is determined to be changed; if the comparison result has no changed data, no newly added data, no missing data and the like, the configuration file of the configuration center is determined to be unchanged.
In the embodiment of the application, under the condition that the configuration file of the configuration center exists in the form of key value pairs, the latest key value pairs are acquired in real time through the monitors of the distributed micro-service, so that the micro-service can acquire the relevant information of the configuration file in time, the latest key value pairs are compared with the historical key value pairs which are the same as keys, whether the configuration file of the configuration center is changed or not is determined, and further the distributed micro-service is subjected to hot update, meanwhile, the micro-service is facilitated to know the change content, the later investigation of problems, rollback configuration and other operations are facilitated, and the real-time performance and efficiency of system maintenance are improved.
S104, when the configuration file of the configuration center is monitored to be changed, the changed configuration file is acquired.
Specifically, in the case where the configuration file of the configuration center is a character string obtained after encoding, as an optional implementation manner, in S104, the obtaining the changed configuration file may include the following steps: acquiring a character string corresponding to the changed configuration file from a configuration center;
And decoding the acquired character strings based on a preset decoding mode to obtain a changed configuration file.
Wherein the decoding mode corresponds to the aforementioned encoding mode, and the decoding operation can be understood as the inverse operation of the encoding operation. Specifically, according to the selected coding mode, a decoding operation is performed by selecting a decoding mode corresponding to the selected coding mode.
According to the embodiment of the application, the configuration file is encoded, so that the system is prevented from being attacked due to data leakage in the configuration file, and the character strings corresponding to the changed configuration file are decoded in a corresponding decoding mode, so that the accuracy of the acquired data in the changed configuration file is ensured, and the stability and the safety of updating of the distributed micro-service system are further improved.
S106, analyzing the changed configuration file through a file analyzer corresponding to the file type of the configuration file to obtain update parameters of the distributed micro service, and loading the update parameters to the distributed micro service to update the distributed micro service.
Wherein the file type of the configuration file is related to the format of the configuration file, such as, but not limited to, xml, yaml, html, text formats. The files of different formats need to be parsed by using corresponding file parsers, for example: for xml files, XMLMapperBuilder resolvers can be used for resolving the changed configuration files to obtain parameters in the configuration files, and the parameters are loaded into the distributed micro-services to update the distributed micro-services.
Wherein the update parameters are a series of parameters required for distributed microservice update, such as database connection information, log level, cache configuration, etc.
It should be understood that in a stand-alone version, the distributed microservices need to be modified for the configuration files of each service, and the configuration files need to be modified are more, so that each update needs to consume a great deal of time and manpower, and the cost of the operation and maintenance of the distributed microservices is increased.
According to the embodiment of the application, under the condition that the configuration file of the configuration center is monitored to change, the changed configuration file is obtained from the configuration center, the configuration file is analyzed by the file analyzer corresponding to the file type of the configuration file to obtain the update parameters, the update parameters are loaded to the distributed micro-service, the distributed micro-service is updated without stopping, going off line, modifying the source code file and other operations, and the dynamic update can be realized during service operation.
Specifically, as an optional implementation manner, in S106, the step of analyzing, by the file analyzer corresponding to the file type of the configuration file, the changed configuration file to obtain the updated parameters of the distributed micro service may include the following steps:
creating a mapping object in an analysis method of a file analyzer, and loading the changed configuration file into the mapping object;
and executing an analysis method, and analyzing the changed configuration file to obtain the updated parameters of the distributed micro-service.
Wherein a mapping object refers to a data structure created when parsing a configuration file, for example: dictionary mapping, etc. for storing information in the configuration file for subsequent use, associating various configuration items in the configuration file with the mapping objects, and obtaining relevant data in the configuration file by querying the mapping objects after parsing.
The embodiment of the application stores the configuration file by creating the mapping object, so that the configuration information is more organized, is convenient to inquire and access, and can load the update parameters obtained through analysis to the distributed micro-service or delete the update parameters from the distributed micro-service through the mapping object, thereby being easy to manage, enabling the system to respond to the configuration change quickly and realizing the dynamic update of the distributed micro-service.
As another optional embodiment, in S106, before loading the update parameter into the distributed micro service to update the distributed micro service, the method may further include the following steps: determining target cache data related to the distributed micro-service from a local cache of the distributed micro-service based on the file identification of the changed configuration file;
clearing the target cache data from the local cache;
and loading the update parameters to the local cache.
Wherein, the cache refers to a quick access layer for storing temporary data.
The target cache data related to the distributed micro service may be a parameter obtained by analyzing the history configuration file, or may be other data that may affect the update.
It should be appreciated that the distributed microservices may use caches to store parameters and other data needed for configuration during operation, and if historical data in the caches is not cleared in time, historical parameters or expired data may continue to be used, resulting in uncertain behavior and causing system errors.
Before loading the update parameters into the distributed micro-service, the embodiment of the application firstly analyzes the parameters obtained by analyzing the history configuration file and the data which possibly influence the update, clears the parameters from the local of the distributed micro-service, ensures the consistency of system configuration, and avoids continuously using the history parameters or the expiration data, thereby enabling the latest configuration information or parameters to be obtained from the local cache before updating the distributed micro-service, realizing dynamic update without restarting the service.
The following describes the method for updating the distributed microservice provided by the embodiment of the present application by a complete example, which should not be construed as limiting the method of the embodiment of the present application. Referring to fig. 2, a flow chart of another method for updating distributed microservices according to an embodiment of the present application is shown.
In this example, the distributed micro-services can be developed and implemented by using Spring Boot or the like in Java, namely, java services; nacos is a configuration center; the configuration file for configuring the Java service is in an xml format, that is, an xml file, a corresponding character string is obtained after encoding by Base64 and is stored in the configuration center Nacos in the form of a key value pair, a key of the key value pair is a file identifier of the configuration file, such as a file name, and a value of the key value pair is a character string corresponding to the configuration file.
First, the Java service registers the listener to Nacos, and when it is detected that there is a newly added key value pair in Nacos, it compares whether the values between the newly added key value pair and the history key value pair are the same according to the key of the key value pair, and determines whether the configuration file is changed. When the configuration file in Nacos is monitored to be changed, base64 decoding is carried out on the value of the newly added key value pair, the changed configuration file is obtained, the updated parameter is obtained through analysis by an xml file analyzer, the historical parameter and related data of Java service in a local cache are cleared according to the key of the newly added key value pair, the updated parameter is loaded into the cache, and the updated parameter is obtained from the cache in the running process of the Java service, so that dynamic updating is realized.
The foregoing describes specific embodiments of the present disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
Corresponding to the above-mentioned method for updating the distributed micro-service shown in fig. 1, the embodiment of the application also provides a device for updating the distributed micro-service.
