sping4.3+ hibernate-validator@Validated注解失效最终解决方法

这里列出我最终解决方法，详细的解决原理我整理一下再发。

最终配置方案： 

 

    
        
            
        
    

--> 

 


 
     

代码：

@Controller
public class MyControllerImpl {
   
    @RequestMapping(method = RequestMethod.POST)
    @ResponseBody
    public String save(@Validated({AddGroup.class}) User entity) {
        System.out.println("验证");
        return "ok";
    }
}

// User.class
public class User implements Serializable {
    /**
     * 主键
     */
    @Id
    @Column(name = "user_id")
    @NotEmpty(message = "主键不能为空", groups = {AddGroup.class})
    private String userId;

    /**
     * 用户名
     */
    @NotEmpty(message = "用户名不能为空", groups = {AddGroup.class})
    private String username;
}

// AddGroup.class
public interface AddGroup {
}

/**
 * MyExceptionHandler.class
 * 异常处理
 */
@RestControllerAdvice("org.tingwen")
public class MyExceptionHandler {

    @ExceptionHandler(BindException.class)
    public Result handleBindException(BindException e) {
        Map data = new HashMap<>();
        for (ObjectError error : e.getAllErrors()) {
            data.put(((FieldError) error).getField(), error.getDefaultMessage());
        }
        Result r = new Result();
        r.setMessage(Message.CHECK_ERROR);
        r.setData(data);
        return r;
    }
}

结果

//发送 post 请求
http://localhost:8080/user

//返回值
{
  "code": -105,
  "data": {
    "userId": "主键不能为空",
    "username": "用户名不能为空"
  },
  "msg": "校验错误"
}
