添加依賴：
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-feign</artifactId>

<dependency>

</dependency>
創建啟動類：
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;
@EnableFeignClients
@EnableDiscoveryClient
@SpringBootApplication
public class UserServiceApplication {
public static void main(String[] args) {
new SpringApplicationBuilder(UserServiceApplication.class).web(true).run(args);
}
}
寫一個feign client：
@FeignClient(name = "這里寫服務名稱")
public interface UserServiceAPI {
@RequestMapping(value = "/user/getUserInfo", method = RequestMethod.GET)
public BaseResponse<UserInfo> getUserInfo(@RequestParam("userId")Integer userId);
測試：
@RestController
public class UserServiceAPITestController {
@Autowired
UserServiceAPI userServiceAPI;
@RequestMapping(value = "/user/getUserInfo", method = RequestMethod.GET)
public BaseResponse<KylinUserInfo> getUserInfoByUserId(Integer userId) {
return userServiceAPI.getUserInfo(userId);
}
}
瀏覽器訪問：localhost:8080/user/getUserInfo
