搭建springcloud服务提供端的搭建过程：这是在《[springcloud入门详细搭建微服务环境-01 ][springcloud_-01]》的基础上进行的。

### 1.先导入springcloud服务提供端的依赖jar包 ###

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-config</artifactId>
            </dependency>

### 2.建一个springcloud服务提供端的入口类 ###

package cn.mesmile;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    
    /**
     * @Created with IDEA
     * @author: Super Zheng
     * @Description: java类作用描述
     * @Date:2019/1/6
     * @Time:11:34
     *
     * @EnableEurekaClient 表示这是一个Eureka的客户端
     */
    @SpringBootApplication
    @EnableEurekaClient
    public class UserApplication {
        public static void main(String[] args) {
            SpringApplication.run(UserApplication.class);
        }
    }

### 3.写一个controller类用于提供服务 ###

package cn.mesmile.controller;
    
    import cn.mesmile.User;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @Created with IDEA
     * @author: Super Zheng
     * @Description: java类作用描述
     * @Date:2019/1/6
     * @Time:11:40
     */
    @RestController
    @RequestMapping("/provider")
    public class UserController {
    
        @RequestMapping("/user/{id}")
        public User getUser(@PathVariable(name = "id") Long id){
            return new User(id,"test");
        }
    }

### 4.写springcloud服务提供端的配置文件 ###

注意：这里的配置文件名 为 application.yml

server:
      port: 8001
    eureka:
      client:
        service-url:
         #defaultZone: http://localhost:7001/eureka #告诉服务提供者要把服务注册到哪里
         defaultZone: http://eureka-7001.com:7001/eureka,http://eureka-7002.com:7002/eureka #集群环境下的配置
      instance:
        prefer-ip-address: true #显示客户端ip
    spring:
      application:
        name: USER-PROVIDER #这是服务提供者在注册中心的别名，别名不要用下划线

### 5.启动注册中心入口类后，启动服务提供端入口类后 ###
