??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
微服務模塊引入：
????????
????????????org.springframework.cloud

????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));
????}

@EnableFeignClients(basePackages?=?"com.atguigu.gulimall.member.feign")
@EnableDiscoveryClient
@SpringBootApplication
public?class?GulimallMemberApplication?{
測試：
????@Autowired
????CouponFeignService?couponFeignService;
????@RequestMapping("coupons")
????public?R?test1(){
????????MemberEntity?memberEntity?=?new?MemberEntity();
????????memberEntity.setNickname("sun");
