@Validated与@Valid的区别

• @Validated可以配合分组使用，如QueryGroup.class，就只校验加了QueryGroup.class的属性
• @Valid只具备基础功能，并不具备分组校验的功能

  @ApiOperation("查询动态跟踪分页")
  @PreAuthorize("@ss.hasPermi('man:manPubDynamic:list')")
  @GetMapping("/page")
  public TableDataInfo<GfManPubDynamicVo> page(@Validated(QueryGroup.class) GfManPubDynamicBo bo) {
      return iGfManPubDynamicService.queryPageList(bo);
  }

  @Data
  @EqualsAndHashCode(callSuper = true)
  @ApiModel("动态跟踪业务对象")
  public class GfManPubDynamicBo extends BaseEntity {
  
      @ApiModelProperty(value = "动态追踪ID", required = true)
      @NotNull(message = "动态追踪ID不能为空")
      private Long dynamicId;
  
      @ApiModelProperty(value = "动态类型（0：未成年，1：低收入，2：为老，3：养老）", required = true)
      @NotNull(message = "动态类型（0：未成年，1：低收入，2：为老，3：养老）不能为空", groups = { AddGroup.class, EditGroup.class })
      private Integer dynamicType;
  
      @ApiModelProperty(value = "动态追踪主图", required = true)
      @NotBlank(message = "动态追踪主图不能为空", groups = { AddGroup.class, EditGroup.class })
      private String pics;
  
      @ApiModelProperty(value = "动态追踪内容", required = true)
      @NotBlank(message = "动态追踪内容不能为空", groups = { AddGroup.class, EditGroup.class })
      private String content;
  
      @ApiModelProperty("灯型状态")
      private Integer lightStatus;
  
      @ApiModelProperty("分页大小")
      private Integer pageSize;
  
      @ApiModelProperty("当前页数")
      private Integer pageNum;
  
      @ApiModelProperty("排序列")
      private String orderByColumn;
  
      @ApiModelProperty(value = "排序的方向", example = "asc,desc")
      private String isAsc;
  }

• 如果@Validated校验未生效，检查自己的SpringBoot版本是否大于2.3，如果是，则需要手动增加以下依赖：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-validation</artifactId>
    </dependency>

• 同时，需要增加全局异常处理器，来发现异常并返回正常校验信息

/**
   * 自定义验证异常
   */
@ExceptionHandler(BindException.class)
public AjaxResult<Void> handleBindException(BindException e) {
  log.error(e.getMessage(), e);
  String message = e.getAllErrors().stream()
      .map(DefaultMessageSourceResolvable::getDefaultMessage)
      .collect(Collectors.joining(", "));
  return AjaxResult.error(message);
}

/**
   * 自定义验证异常
   */
@ExceptionHandler(ConstraintViolationException.class)
public AjaxResult<Void> constraintViolationException(ConstraintViolationException e) {
  log.error(e.getMessage(), e);
  String message = e.getConstraintViolations().stream()
      .map(ConstraintViolation::getMessage)
      .collect(Collectors.joining(", "));
  return AjaxResult.error(message);
}

/**
   * 自定义验证异常
   */
@ExceptionHandler(MethodArgumentNotValidException.class)
public AjaxResult<Void> handleMethodArgumentNotValidException(MethodArgumentNotValidException e) {
  log.error(e.getMessage(), e);
  String message = e.getBindingResult().getFieldError().getDefaultMessage();
  return AjaxResult.error(message);
}
