import
1、nacos注册中心
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
@EnableDiscoveryClient
@SpringBootApplication
@MapperScan("com.sun.user.mapper")
public class RoleApplicaion {
public static void main(String[] args) {
SpringApplication.run(RoleApplicaion.class, args);
}
}
application:
name: acgn-user
2、OpenFeign
微服务模块引入：
org.springframework.cloud
spring-cloud-starter-openfeign
被调用微服务：
@RestController
@RequestMapping("coupon/coupon")
public class CouponController {
@Autowired
private CouponService couponService;
@RequestMapping("/member/list")
public R membercoupons(){
CouponEntity couponEntity = new CouponEntity();
couponEntity.setCouponName("100-10");
return R.ok().put("coupons", Arrays.asList(couponEntity));
}
调用
package com.atguigu.gulimall.member.feign;
import com.atguigu.common.utils.R;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
@FeignClient("gulimall-coupon")
public interface CouponFeignService {
@RequestMapping("/coupon/coupon/member/list")
public R membercoupons();
}
@EnableFeignClients(basePackages = "com.atguigu.gulimall.member.feign")
@EnableDiscoveryClient
@SpringBootApplication
public class GulimallMemberApplication {
测试：
@Autowired
CouponFeignService couponFeignService;
@RequestMapping("coupons")
public R test1(){
MemberEntity memberEntity = new MemberEntity();
memberEntity.setNickname("sun");
R memberCoupons = couponFeignService.membercoupons();
return R.ok().put("member", memberEntity).put("coupons", memberCoupons.get("coupons"));
}
