spring-cloud供应者消费者模式(下)：配置消费者

## **配置消费者** ##

首先先创建项目，选择左侧的导航栏的**Spring Initializr**，然后默认是Default选项。

对项目信息进行编辑，填写组织名和项目名。

选择Cloud Discovery，然后右侧选择Eureka Discovery(因为创建的是客户端，所以选择Discovery)。

编辑项目名及存放路径，然后下一步就创建完项目了：

创建好的项目展示：

接下来配置文件：

往pom.xml文件添加所需jar包和配置，请大家根据版本选择(我用的是Dalston，所以parent标签里的version是1.5.x版本，spring-cloud.version是Dalston)：

            </repository>
        </repositories>
    
    </project>

然后到SpringbootEurekaClientCustomerApplication文件里加入注解：

@EnableDiscoveryClient
    @EnableFeignClients

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 5][]

接下来在resources文件下的application.properties(我把后缀改成yml，效果相同)配置代码：

#配置端口号
    server:
      port: 7002
    spring:
    #应用名称
      application:
        name: tencent-user-customer
    eureka:
      client:
    #访问路径
        service-url:
          defaultZone: http://root:111111@localhost:7000/eureka/

在java文件下的springbooteurekaclientcustomer文件下创建一个Controller(后续需要测试消费者和供应者)，必须和SpringbootEurekaClientCustomerApplication同级

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 6][]

controller里的代码：

UserClient文件代码：

package com.szxs.springbooteurekaclientcustomer.controller;
    
    import org.springframework.cloud.netflix.feign.FeignClient;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    @FeignClient(name = "tencent-user-provider") //name值填的是供应者application.yml里设置的application.name的值
    public interface UserClient {
    
        @RequestMapping(value = "/login",method = RequestMethod.GET)
        public String login();
    
    }

UserClientController文件代码：

package com.szxs.springbooteurekaclientcustomer.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import javax.annotation.Resource;
    
    @RestController
    public class UserClientController {
    
        @Resource
        private UserClient userClient;
    
        @RequestMapping("/UserLogin")
        public String userLogin(){
            return "消费者"+userClient.login();
        }
    
    }

然后点击右上角的虫子(Debug)启动，将服务中心和供应者和消费者的项目启动起来

![20190115212836766.jpg][]

然后一个个访问，先访问供应者路径，记得加上controller的请求映射名称：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 7][]

接下来访问消费者的路径，记得加上controller的请求映射名称：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 8][]

最后访问服务中心，如图所示供应者消费者名称显示，便配置成功：
