Spring - HV000030: No validator could be found for constraint ‘xx‘ validating type ‘java.lang.Intege

   在测试接口的时候，传入的对象值为integer时，后端报错，看起来是提醒我检查‘pageWith’这个字段的配置。。。其实是项目中使用的校验注解所支持的数据类型与实体中字段的类型不符合。

    @NotEmpty(message = "{vo.email.title.empty}")
    @ApiModelProperty(value = "邮件标题", required = true, example = "email001")
    @Length(max = 20, message = "{vo.email.title.length}")
    private String caption;

    @NotEmpty(message = "{vo.email.page.width.empty}")
    @ApiModelProperty(value = "页面宽度", required = true, example = "600")
    private Integer pageWidth;

修改为：由原来的@NotEmpty -->  @NotNull

    @NotEmpty(message = "{vo.email.title.empty}")
    @ApiModelProperty(value = "邮件标题", required = true, example = "email001")
    @Length(max = 20, message = "{vo.email.title.length}")
    private String caption;

    @NotNull(message = "{vo.email.page.width.empty}")
    @ApiModelProperty(value = "页面宽度", required = true, example = "600")
    @Range(min = 600, max = 800, message = "{vo.email.page.width.exception}")
    private Integer pageWidth;

@NotNull

不能为 null，但可以为 empty，一般用在 Integer 类型的基本数据类型的非空校验上，而且被其标注的字段可以使用 @size、@Max、@Min 对字段数值进行大小的控制

@NotEmpty

不能为 null，且长度必须大于 0，一般用在集合类上或者数组上
