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。

1. 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><parent><groupId>com.ml.honghu</groupId><artifactId>commonservice</artifactId><version>0.0.1-SNAPSHOT</version></parent><artifactId>commonservice-config</artifactId><packaging>jar</packaging><name>commonservice-config</name><description>Config Server</description><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-config-server</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-eureka</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId>

</project>

1. 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); } 

1. 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 

到此，整个 config 服务项目配置完毕！！
