golang基于spf13/viper 和 shima-park/agollo 实现本地配置文件和远程apollo配置中心多实例快速接入
go get -u github.com/jinzaigo/xconfig
- 支持viper包诸多同名方法
- 支持本地配置文件和远程apollo配置热加载，实时更新
- 使用sync.RWMutex读写锁，解决了viper并发读写不安全问题
- 支持apollo配置中心多实例配置化快速接入
指定配置文件路径完成初始化，即可通过xconfig.GetLocalIns().xxx()链式操作，读取配置
package main
import (
"fmt"
"github.com/jinzaigo/xconfig"
)
func main() {
if xconfig.IsLocalLoaded() {
fmt.Println("local config is loaded")
return
}
//初始化
configIns := xconfig.New(xconfig.WithFile("example/config.yml"))
xconfig.InitLocalIns(configIns)
//读取配置
fmt.Println(xconfig.GetLocalIns().GetString("appId"))
fmt.Println(xconfig.GetLocalIns().GetString("env"))
fmt.Println(xconfig.GetLocalIns().GetString("apollo.one.endpoint"))
}xxx支持的操作方法：
- IsSet(key string) bool
- Get(key string) interface{}
- AllSettings() map[string]interface{}
- GetStringMap(key string) map[string]interface{}
- GetStringMapString(key string) map[string]string
- GetStringSlice(key string) []string
- GetIntSlice(key string) []int
- GetString(key string) string
- GetInt(key string) int
- GetInt32(key string) int32
- GetInt64(key string) int64
- GetUint(key string) uint
- GetUint32(key string) uint32
- GetUint64(key string) uint64
- GetFloat(key string) float64
- GetFloat64(key string) float64
- GetFloat32(key string) float32
- GetBool(key string) bool
- SubAndUnmarshal(key string, i interface{}) error
指定配置类型与apollo信息完成初始化，即可通过xconfig.GetRemoteIns(key).xxx()链式操作，读取配置
单实例场景
//初始化
configIns := xconfig.New(xconfig.WithConfigType("properties"))
err := configIns.AddApolloRemoteConfig(endpoint, appId, namespace, backupFile)
if err != nil {
...handler
}
xconfig.AddRemoteIns("ApplicationConfig", configIns)
//读取配置
fmt.Println(xconfig.GetRemoteIns("ApplicationConfig").AllSettings())多实例场景
在本地配置文件config.yaml维护apollo配置信息，然后批量完成多个实例的初始化，即可通过xconfig.GetRemoteIns(key).xxx()链式操作，读取配置
#apollo配置，支持多实例多namespace
apollo:
one:
endpoint: xxx
appId: xxx
namespaces:
one:
key: ApplicationConfig #用于读取配置，保证全局唯一，避免相互覆盖

type: properties
two:
key: cipherConfig
name: cipher
type: properties
backupFile: /tmp/xconfig/apollo_bak/test.agollo #每个appId使用不同的备份文件名，避免相互覆盖package main
