2.Feign

只调用端处理：
1.依赖

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

2.启动
添加注解

@EnableDiscoveryClient
@EnableFeignClients

3.代码

@FeignClient("base")
public interface BaseClient {
    @GetMapping("/label/{id}")
    public Result findById(@PathVariable("id") String id);
}

4.测试

    @Autowired
    private BaseClient baseClient;
    @GetMapping("/label/{id}")
    public Result findByLabelId(@PathVariable("id") String id) {
        return baseClient.findById(id);
    }

请求从接口，会调用base微服务的接口
