Spring cloud 之Feign基本使用
首先导入feign的依赖:
<!-- 添加feign声明式webservice client --> <dependence> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-feign</artifactId> </dependence>
主程序:
@SpringBootApplication @EnableEurekaClient // 支持声明式webService client @EnableFeignClients public class SpringCloudMovieApplication { public static void main(String[] args) { SpringApplication.run(SpringCloudMovieApplication.class,args); } }
Feign客户端接口:
// name属性表示请求哪个微服务,这里请求的是用户微服务,name表示用户微服务的vip @FeignClient(name="spring-cloud-user") public interface IUserService { @RequestMapping(value="/user/{id}",method=RequestMethod.GET) // 注意这里不支持@GetMapping // @PathVariable("id")不这么写,会报错: // PathVariable annotation was empty on param 0 public User findUserById(@PathVariable("id")Long id); }
