spring cloud config  配置中心

配置中心分为  server 服务端 client 和客户端，

服务端搭建

spring boot 启动类  注意spring boot 的启动类需要放到某一个包下，不能直接在 src 目录下

package app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Administrator on 2017/8/16.
 */
@SpringBootApplication  
@EnableConfigServer   // 配置中心服务
public class ConfigSreviceApplication {

    public static void main(String [] args){
        SpringApplication.run(ConfigSreviceApplication.class);
    }
}

properties 配置

server.port=4555 #git 仓库地址 spring.cloud.config.server.git.uri=https://github.com/cyyinfo/spring-cloud-config-demo.git

#如果配置文件不在仓库的根目录则需要配置此项，为配置文件所在目录
spring.cloud.config.server.git.search-paths=config-repository

到这里一个最简单的配置服务端搭建完成，启动后访问

http://localhost:4555/spring-cloud-config-sevice-demo/master  可以看到结果

http://localhost:4555/[git 仓库项目名称]/[profile 默认master]

client  端搭建

</project>

启动类

package app;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Administrator on 2017/8/16.
 */

@RestController
@SpringBootApplication
@RequestMapping("/")
public class ConfigClientApplication {

    @Value("${test.demo.name}")
    private String testDemoName;

    @RequestMapping("")
    public String index(){
        return "config clicent testDemoName="+this.testDemoName+"#";
    }

    public static void main(String [] args){
        SpringApplication.run(ConfigClientApplication.class);
    }
}

配置文件  注意是  bootstrap.properties 而不是 application.properties

spring.cloud.config.env=spring-cloud-config-sevice-demo  // git 仓库名称
spring.cloud.config.profile=prev  // 配置氮气环境 决定是加载git仓库中的 application-prev.propertis haishi
spring.cloud.config.label=master  // git 分支名 
spring.cloud.config.uri=http://localhost:4555   // 配置中心项目访问地址


spring.application.name=my-config-client
server.port=4556
