校验实体类注解

@Data
@NoArgsConstructor
@AllArgsConstructor
@JsonIgnoreProperties(ignoreUnknown=true)
public class ThirdAlarmInfoRequest {
    /**
     * 报警id
     */
    @NotNull(message = "报警id为空",groups = {Add.class})
    private Long alarmId;
    /**
     * 报警时间
     */
    @NotNull(message = "报警时间为空",groups = {Add.class})
    private Date alarmTime;
    /**
     * 报警州市
     */
    @org.hibernate.validator.constraints.NotBlank(message = "报警州市为空",groups = {Add.class})
//    @NotBlank(message = "报警州市为空",groups = {Add.class})
    private String alarmCity;
