Referring to FIG. 4, the gateway automatic adaptation method according to the present invention first selects a target gateway to be adapted for automatic gateway adaptation (S410).

In addition, the WSDL document of the target gateway is obtained to extract the info-meta data for the API-specific modification analysis of the corresponding target gateway (S420, S430). In this case, the WSDL document of the target gateway may be obtained and stored in advance, or may be taken from the URL address of the target gateway.

Then, the info-meta data of the extracted target gateway and the info-meta data in the library of the open service generation tool are compared / analyzed to identify parameters that need to be modified for each API (S440).

And providing the user with an API and related modification information and a modification environment that need to be corrected in the comparison / analysis result (S450), modifying the code of the open service generation tool according to the user's selection through the provided modification environment, and modifying the code. Recompile (S460, S470).

The gateway on which the open service generation tool to which the adaptation target is applied depends is changed to the selected target gateway, and the open service program generated through the open service creation tool is dependent on the selected target gateway.

5 is a functional block diagram showing a gateway automatic adaptation apparatus of the present invention implemented to implement the gateway automatic adaptation method.

Referring to FIG. 5, the apparatus for automatic gateway adaptation according to the present invention includes a user interface block 51, an analysis block 52, an IED adaptation block 53, and first and second databases 54 and 55. It includes.

The user interface block 51 provides a GUI with procedures necessary for adapting the service generation tool to the user, and includes an environment file generation / change support unit 511 and a web service change support unit 512. The environment file generation / change support unit 511 provides a function of automatically generating an environment file such as an IP address or a makefile required for adaptation with a target gateway, or changing the contents of an existing file, and the web service change support unit. 512 provides to change a web service URL or the like for adaptation with the selected target gateway.

The analysis block 52 analyzes a portion of the open service generation tool for modification using the info-meta data information of the target gateway and the open service generation tool, and analyzes the analysis result in the user interface block 51 or To the IDE adaptation block 53. To this end, the analysis block 52 obtains and parses a WSDL (Web Service Description Language) document of a target gateway that describes the target gateway and provides an access method, extracts information necessary for adaptive analysis, and extracts information-metadata. A parser 521 for generating and storing the generated info-meta data of the target gateway in the first database 54, and open-services with the info-meta data of the target gateway stored in the first database 54. It includes an adaptive checker 522 to compare and analyze the info-meta data of the generation tool to find the portion that needs to be corrected and to store in the second database (55).

The IDE adaptation block 53 uses an IDE (Integrated Development Environment) in the advanced modification for the API level adaptation using the results analyzed in the analysis block 52 so that the user can change the logic inside the open service library. To help.

The first database 54 stores the info-meta data of the target gateway prepared by the parsing in the analysis block 52 and the info-meta data of the open service creation tool.

The second database 55 stores the result data analyzed in the analysis block 52 and provides the analysis result data stored in the user interface block 51 and the IDE adaptation block 53.

6 shows a structure of info-meta data used for adaptive analysis in the present invention.

The info-meta data indicates information necessary for adaptive analysis for each API, and includes an interface name (601), a return type (602), for identifying a corresponding API, and a return type (602); The number of input parameters 603 and input parameter type 604 field information are included. In this case, the number of field types 604 of the input parameters should be the same as the field value of the number 603 of the input parameters, and should have an order. For example, when the number 603 of the input parameters is six, the number of the input parameter type 604 fields is six, indicating the types for the six input parameters.

7 is a flowchart illustrating an operation procedure in the gateway automatic adaptation apparatus according to the present invention, and the operation in the gateway automatic adaptation apparatus described above will be described with reference to the flowchart.

First, the user interface block 51 provides the user with a GUI for a gateway adaptation procedure for the corresponding open service generation tool, through which the user selects and inputs a target gateway to be adapted. The selected target gateway information is provided from the user interface block 51 to the analysis block 52. In this case, the target gateway information may be input as a URL address.

Accordingly, the parser 521 of the analysis block 52 obtains a WSDL document describing information on the access method and service of the target gateway from the URL address of the selected target gateway (S701), and parses the obtained WSDL document. The analysis extracts the info-meta data, which is information necessary for the adaptive analysis, and stores the extracted info-meta data in the first database 54 (S702). In this case, the info-meta data has a form as shown in FIG. 6, and provides adaptation information required for each API provided by the target gateway.

When the info-meta data of the target gateway is prepared as described above, the adaptive checker 522 of the analysis block 52 performs the info-meta data of each API described in the library of the open service generation tool (not shown) and the target gateway. Analyze the info-meta data (S703).

While performing the analysis process, the adaptive checker 522 first compares the info-meta data of the target gateway with the interface name of the info-meta data of each API in the library of the open service generation tool (S704).

If there is info-meta data that matches the interface name as a result of the comparison, the next fields of the info-meta data, i.e., return type 602, number of input parameters 603, and type of input parameters 604 If there is a field that does not match, and the field value does not match (S705 to S707), the information necessary to modify the API corresponding to the corresponding info-meta data is stored in the second database 55 (S708).

If all the field values are the same between two info-meta data having the same interface name, modification for adaptation of the corresponding API is unnecessary, but if any field value is different, the information for each API of the open service creation tool The value of an item corresponding to a field having a difference in meta data should be corrected to a field value of info-meta data of a target gateway having the same interface name. Therefore, the information stored in the step S708 is preferably stored to know the API to be modified, and what items (ie, parameters) to be modified in the API.

Steps S704 to S708 are repeated for the info-meta data of all APIs, so that all APIs in the open service creation tool can obtain information that needs to be modified for adaptation with the target gateway, which is the second database. Stored at 55.

Information necessary for adaptation to the target gateway stored in the second database 55 is provided to the user interface block 51 and the IDE adaptation block 53, and the user interface block 51 is provided to the user through the GUI environment. It shows the types of API and related parameters that need to be modified for adaptation, and the input parameter / return type of the corresponding API is automatically modified by the developer's selection which confirmed this, or the IDE adaptation block 53 It provides an IDE environment for developers to modify their code, which allows developers to modify their own code. The gateway adaptation apparatus of the present invention recompiles the modified codes as described above so that the modified codes are applied to the corresponding open service gateway.

When the open service generation apparatus is configured by applying the gateway adaptation apparatus of the present invention, the open service generation tool may be configured as shown in FIG. 8.

Has That is, as described with reference to FIG. 5, the user interface block 51 includes the user interface block 51, the analysis block 52, the IDE adaptation block 53, and the first and second databases 54 and 55. After providing the user with a procedure for gateway adaptation through a target gateway, when the target gateway is input, the WSDL document of the corresponding target gateway is read through the analysis block 52 to generate API-specific data for each API in the target gateway. The info-meta data of the target gateway is compared with the info-meta data for each API of the library in the open service generation device, and the user through the user interface block 51 provides parameter information to be modified for the API having different field values. The adaptation block 53 provides an environment for directly modifying code in the library, and then recompiles the modified code.

Next, the service building unit 82 provides the user with the library re-reviewed through the gateway adaptation unit 81 to configure the logic of the service desired by the user, and executes the service logic configured by the user as an open service program. Make. Since the created open service program is implemented as a library adapted to the target gateway by the gateway adaptation unit 81, the open service program can be adapted to the target gateway. In addition, when interworking with another gateway is desired, the other gateway may be selected and adapted through the gateway adaptation unit 81, so that the open service program generated by the open service generating apparatus of the present invention is not dependent on a specific gateway. In addition, it is possible to create an open service program that can adapt to any gateway desired by the user.

The generated open service program is mounted on the application server through the service arrangement unit 83 and then adapts to the actual target gateway.

The open service creation procedure by the open service creation device having the gateway adaptation function is performed as follows.

The open service generation apparatus according to the present invention provides a target gateway desired by a user (ie, a program developer) by providing one or more target gateways through which the gateway adaptation unit 81 may store info-meta data or check WSDL. Allows you to choose one.

As a result, when the developer selects the target gateway, the gateway adaptor 81 obtains the stored info-meta data of the corresponding gateway, or receives the WSDL document from the URL address of the selected target gateway and parses the info-meta through the parsing process. Extract the data.

The info-meta data of the target gateway thus obtained is compared and analyzed with the info-meta data of the library provided by the corresponding open service generation device, and the analysis result target gateway is performed through the user interface block 51 or the IDE adaptation block 53. Provides API and related modification information with different and parameters, automatic modification and compilation environment, and environment for advanced modification through IDE.

Therefore, the developer can be automatically provided with the modification information by simply selecting the target gateway without having to manually review and find the code to modify. In addition, the developer can make modifications automatically through the provided modification environment or the IDE environment. You can also modify it directly.

When the modification is completed, the gateway adaptation unit 81 recompiles the modified code so that the open service generation apparatus is adapted to the selected target gateway.

After that, the developer can generate a desired open service program through an open service generating device. For this purpose, the service building unit 82 can visualize an advanced programmable SDK (Software Development Kit) environment and a GUI that enables quick and easy development. Provide an environment.

Therefore, the developer describes the logic of the desired open type service by using the library adapted by the gateway adaptation unit 81 through the SDK environment and the GUI provided through the service building unit 82, and the service building unit ( 82 generates the described logic into an executable open service program.

The open service program generated as described above is matched with the target gateway selected through the service arrangement unit 83.
