Spring Cloud云服务架构 - commonservice-config配置服务搭建

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">

    <build>

            <plugin>

                                    <execution>

                                            </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：

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！
