2.配置中心-基于go实现nacos配置中心

package main

import (

            Port:   8848,
        },
    }

    cc := constant.ClientConfig{
        NamespaceId:         "c1872978-d51c-4188-a497-4e0cd20b97d5", // 如果需要支持多namespace，我们可以场景多个client,它们有不同的NamespaceId
        TimeoutMs:           5000,

    configClient, err := clients.CreateConfigClient(map[string]interface{}{

        "clientConfig":  cc,
    })
    if err != nil {
        panic(err)
    }

    content, err := configClient.GetConfig(vo.ConfigParam{

        Group:  "dev"})

    if err != nil {
        panic(err)
    }
    //fmt.Println(content) //字符串 - yaml
    serverConfig := config.ServerConfig{}

    json.Unmarshal([]byte(content), &serverConfig)
    fmt.Println(serverConfig)

    //  OnChange: func(namespace, group, dataId, data string) {
    //      fmt.Println("配置文件变化")
    //      fmt.Println("group:" + group + ", dataId:" + dataId + ", data:" + data)
    //  },
    //})
    //time.Sleep(3000 * time.Second)
