向控制器发出http GET时发生404错误

Question

我在项目中为我的API服务提供了一个单独的模块，它是新包含的。但我无法向此模块中的控制器发出HTTP请求。

项目主pom文件：

 </project>

api模块中的控制器类：

@Controller
@RequestMapping("/user")
public class UserController {

 @Autowired
UserService userService;
   @RequestMapping(value = "/user", method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<List<User>> listAllUsers() {
    List<User> users = userService.getAllActiveUsers();
    if (users.isEmpty()) {
        return new ResponseEntity<List<User>>(HttpStatus.NO_CONTENT);
    }
    return new ResponseEntity<List<User>>(users, HttpStatus.OK);
    }

  }

项目建设很好。我可以向这些其他模块中的控制器发出HTTP请求但是这个api模块。我总是得到404错误。

我做的GET请求：

http://127.0.0.1:8080/quiz-rest/user

这可能是什么原因？哪里可能出错？ 提前致谢。
