1. 介绍

Spring Cloud Config为分布式系统中的外部配置提供服务器和客户端支持。使用Config Server，您可以在所有环境中管理应用程序的外部属性。客户端和服务器上的概念映射与Spring Environment和PropertySource抽象相同，因此它们与Spring应用程序非常契合，但可以与任何以任何语言运行的应用程序一起使用。随着应用程序通过从开发人员到测试和生产的部署流程，您可以管理这些环境之间的配置，并确定应用程序具有迁移时需要运行的一切。服务器存储后端的默认实现使用git，因此它轻松支持标签版本的配置环境，以及可以访问用于管理内容的各种工具。很容易添加替代实现，并使用Spring配置将其插入。

2. 引入pom相关jar包，其中pom.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>    
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <plugin>

            </plugin>    
        </plugins>    
    </build>    
</project>    

 3. 在src/main/java进行ConfigApplication.java启动文件配置：

package com.ml.honghu;    
    
import org.springframework.boot.SpringApplication;    
import org.springframework.boot.autoconfigure.SpringBootApplication;    
import org.springframework.cloud.config.server.EnableConfigServer;    
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;    
    
@EnableConfigServer    
@EnableEurekaClient    
@SpringBootApplication    
public class ConfigApplication {    
    
    public static void main(String[] args) {    
        SpringApplication.run(ConfigApplication.class, args);    
    }    
}    

 4. 在src/main/resource下进行bootstrap.yml配置

server:     
port: 8888    
spring:    
  application:    
    name: commonservice-config-server    
  profiles:    
    active: discovery,native    
  cloud:    
    config:    
      server:    
        git:    
          uri: http://192.168.0.254/honghu.../honghu-config.git    
          username: honghu    
          password: 123456    
          searchPaths: config-dev    
security:    
  basic:    
    enabled: true    
  user:    
    name: honghu    
    password: 123456    
eureka:    
  client:    
    serviceUrl:    
      defaultZone: http://honghu:123456@localhost:8761/eureka/    
      honghuZone: http://honghu:123456@localhost:8761/eureka/    
    registry-fetch-interval-seconds: 300    
    availability-zones:    
      honghu: honghuZone    
  instance:    
    prefer-ip-address: true    
    metadataMap:    
      version: 1.0    
      variant: A    
      user: ${security.user.name}    
      password: ${security.user.password}    
management:    
  security:    
    enabled: false    

注意： 如果不从远程git或者svn库加载配置文件信息，可以配置加载本地地址，比如window下配置使用：

server:     
port: 8888    
spring:    
  application:    
    name: commonservice-config-server    
  profiles:    
    active: discovery,native    
  cloud:    
    config:    
      server:    
        <span style="color: #ff0000;">native.searchLocations: d:/honghu-config</span>    
security:    
  basic:    
    enabled: true    
  user:    
    name: honghu    
    password: 123456    
eureka:    
  client:    
    serviceUrl:    
      defaultZone: http://honghu:123456@localhost:8761/eureka/    
      honghuZone: http://honghu:123456@localhost:8761/eureka/    
    registry-fetch-interval-seconds: 300    
    availability-zones:    
      honghu: honghuZone    
  instance:    
    prefer-ip-address: true    
    metadataMap:    
      version: 1.0    
      variant: A    
      user: ${security.user.name}    
      password: ${security.user.password}    
management:    
  security:    
    enabled: false
