@ApiModelProperty(value = "小组id")@NotEmpty(message = "小组id 不能为空")private Integer teamId;

1.假如不小心Integer使用@NotEmpty注解报错

提示：

No validator could be found for constraint 'javax.validation.constraints.NotEmpty' validating type 'java.lang.Integer'. Check configuration for 'teamId' error type: javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint 'javax.validation.constraints.NotEmpty' validating type 'java.lang.Integer'. Check configuration for 'teamId'

 

解决方案：

@NotNull换成这个

@ApiModelProperty(value = "小组id")

@NotNull(message = "小组id 不能为空")

private Integer teamId;
