**背景：在[springcloud（三）][springcloud]基础上继续**

### 创建服务消费者Feign ###

**1. 创建工程spring-cloud-feign，pom.xml文件内容如下**

<?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">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>com.zsx</groupId>
        <artifactId>spring-cloud-feign</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <packaging>jar</packaging>
    
        <name>spring-cloud-feign</name>
        <description>Spring Cloud Feign project</description>
    
        <parent>
            <groupId>com.zsx</groupId>
            <artifactId>spring-cloud-customize-dependencies</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <relativePath>../spring-cloud-customize-dependencies/pom.xml</relativePath>
        </parent>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-openfeign</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <mainClass>com.zsx.FeignApplication</mainClass>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </project>

**2. application.yml配置文件内容**

server:
      port: 8085
    spring:
      application:
        name: spring-cloud-feign
    
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:8081/eureka/

**3. 测试服务接口**

package com.zsx.service;
    
    import org.springframework.cloud.openfeign.FeignClient;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    
    @FeignClient("spring-cloud-eureka-client")
    public interface FeignTestService {
    
        @GetMapping(value = "/api/v1/test/{message}")
        String get(@PathVariable("message") String message);
    }

**4. 调用api接口**

package com.zsx.api.controller;
    
    import com.zsx.service.FeignTestService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.http.HttpStatus;
    import org.springframework.http.ResponseEntity;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @RequestMapping("feign/")
    public class FeignTestController {
    
        @Autowired
        private FeignTestService feignTestService;
    
        @GetMapping("/{message}")
        public ResponseEntity get(@PathVariable("message") String message) {
            return new ResponseEntity(feignTestService.get(message), HttpStatus.OK);
        }
    }

**5. 引导类**

package com.zsx;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.cloud.openfeign.EnableFeignClients;
    
    @SpringBootApplication
    @EnableDiscoveryClient
    @EnableFeignClients
    public class FeignApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(FeignApplication.class, args);
        }
    }

**6. 启动注册中心，服务提供者、Feign消费者**
