Call -feign between springcloud service

Requirements: in order to call customer service, check out the user information in the order in

order-service和user-service

1.user-service normally provided controller interfaces

/ ** The query user id User Information 
  * @param 
  * @return 
  * / 
 @RequestMapping (value = "/ {id}", Method = RequestMethod.GET) 
 @ApiOperation (value = "The user id querying user information", notes = "The user id querying user information") 
 public ResponseData getUserInfo (@PathVariable ( "id") Long id, @ RequestParam ( "userType") int userType) { 
     return ResponseDataUtil.buildSuccess ( "200 is", "query is successful", userService .getUserInfoById (ID, userType)); 
 }

2.user-service in the application, enabled feign client

 

@EnableDiscoveryClient
@SpringBootApplication
@EnableFeignClients
@ComponentScan("com.****")
public class TmsUserApplication {
   public static void main(String[] args) {
      SpringApplication.run(TmsUserApplication.class, args);
   }

}

3.order-service api to write a definition of the interface, and user-service in the same way as the controller

/ ** 
 * User Information 
 * @description 
 * @author Guo 
 * @date 2019-10-31 
 * / 
@FeignClient (value = "User--Service", configuration = FeignConfiguration.class) configuration // here transmitted directly to the service header , user-service service name is the user 
public interface UserService { 

    / ** 
     * querying user information 
     * @param 
     * @return 
     * / 
    @RequestMapping (value = "/ API /. 1 / user / users / {ID}", Method = RequestMethod ... GET) 
    public the Map <String, Object> getUserInfoById (@PathVariable ( "ID") ID Long, @RequestParam ( "userType") userType int); 
}

4.order-service in business methods, direct reference

 

@Autowired
private UserService userService;

 userService.getUserInfoById(1,1);
