# 一 引入OpenFeign #

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-openfeign</artifactId>
    </dependency>

# 二 编写一个远程接口，告诉SpringCLoud这个接口需要被远程调用 #

修改“com.bigdata.gulimall.coupon.controller.CouponController”，添加以下controller方法：

@RequestMapping("/member/list")
    public R membercoupons(){
        CouponEntity couponEntity = new CouponEntity();
        couponEntity.setCouponName("满100减10");
        return R.ok().put("coupons",Arrays.asList(couponEntity));
    }

新建“com.bigdata.gulimall.member.feign.CouponFeignService”接口

/**
    * 这是一个声明式的远程调用
    */
    @FeignClient("gulimall-coupon")
    public interface CouponFeignService {
        @RequestMapping("/coupon/coupon/member/list")
        public R membercoupons();
    }

修改“com.bigdata.gulimall.member.GulimallMemberApplication”类，添加上"@EnableFeignClients"：开启远程调用功能

@EnableFeignClients(basePackages = "com.atguigu.gulimall.member.feign")
    @EnableDiscoveryClient
    @SpringBootApplication
    public class GulimallMemberApplication {
        public static void main(String[] args) {
            SpringApplication.run(GulimallMemberApplication.class, args);
        }
    }

# 三 远程调用的使用 #

@RequestMapping("/coupons")
    public R test(){
        MemberEntity memberEntity = new MemberEntity();
        memberEntity.setNickname("张三");
    
        R membercoupons = couponFeignService.membercoupons();
        return R.ok().put("member",memberEntity).put("coupons",membercoupons.get("coupons"));
    }

# 四 启动 GulimallMemberApplication 和  GulimallMemberApplication微服务进行测试 #

1 浏览器输入  [http://localhost:8000/member/member/coupons][http_localhost_8000_member_member_coupons]

2 输出结果
