spring cloud config server配置

pom.xml

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-server</artifactId>
</dependency>

application.yml

server:
  port: 8080
spring:
  application:
    name: spring-cloud-config-server-wly
  cloud:
    config:
      server:
        # git配置：项目/${search-paths}/${application}-${profile}.properties
        # cloud-config-wly/config/config/neo-config-dev.properties
        git:
          # 项目地址，换成自己的项目地址
          uri: git@xxx:xxxx/cloud-config-wly.git
          # 表示文件路径
          search-paths: config
          # 项目用户名，换成项目用户名
          username: xxx
          # 项目密码，换成项目密码
          password: xxx

启动类（新增@EnableConfigServer注解）

package com.wang.springcloudconfig;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;

@EnableConfigServer
@SpringBootApplication
public class SpringcloudconfigApplication {

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

启动服务

http://localhost:8080/wly-config/dev

spring cloud config client配置

pom.xml

<!-- 引入spring cloud config 客户端配置 -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<!-- 引入web模块 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

application.yml同级目录（src/main/resources）新增配置文件：bootstrap.properties

此文件会先于application.yml加载

# 相当于${application}
spring.cloud.config.name=wly-config
# 相当于${profile}
spring.cloud.config.profile=product
# 配置中心server服务url
spring.cloud.config.uri=http://localhost:8080/
# 相当于git分支
spring.cloud.config.label=master

application.yml

spring:
  application:
    name: spring-cloud-config-client
server:
  port: 8081

controller

package com.wang.springcloudconfigclient.web;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @Author wly
 * @Date 2018/7/2 11:35
 */
@RestController
public class HelloController {
    @Autowired
    private Environment env;

    @RequestMapping("/test")
    public String test() {
        return env.getProperty("local.ip") + "," + env.getProperty("local.port");
    }
}

访问

http://localhost:8081/test
