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">    
        <modelVersion>4.0.0</modelVersion>

                    <executions>    
                        <execution>    
                            <id>1</id>    
                            <goals>    
                                <goal>repackage</goal>    
                            </goals>    
                        </execution>    
                                        <execution>    
                                            <id>2</id>    
                                                <goals>    
                                                       <goal>build-info</goal>    
                                                </goals>    
                                        </execution>    
                    </executions>    
                </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：欢迎大家一起学习研究相关技术愿意了解源码的朋友直接求求交流分享技术：2147775633

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

到此，整个config服务项目配置完毕！！
