<!--引入open feign依赖--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency></dependencies>

2.启动注解

@SpringBootApplication@EnableDiscoveryClient@EnableFeignClientspublic class UserservicesApplication { public static void main(String[] args) { SpringApplication.run(UserservicesApplication.class, args); }}

3.接口

@FeignClient("productservices")public interface ProductClient { @RequestMapping("/product/findAll") public Map findAll();}

4.服务调用

@Autowiredprivate ProductClient productClient; @RequestMapping("/user/showProductMsg")public Map showProductMsg() { Map msg = productClient.findAll(); return msg;}

5.超时设置

feign.client.config.default.connectTimeout=5000 #配置所有服务连接超时
feign.client.config.default.readTimeout=5000 #配置所有服务等待超时
