原因
JAVA 类中 属性类型 映射 Mybatis 或 hibernate 异常

order by t.last_operate_time desc ,t.sort_field desc
</select>
此处是
TIMESTAMPDIFF( SECOND,( SELECT DATE_ADD( t.create_time, INTERVAL 24 HOUR )), NOW() ) AS validTime
映射
validTime 属性报错
解决方式和总结
改为 BigInteger 即可
后续如果还是遇到类似的问题，不知道用什么包装类型接收，可以用 Object 作为类型。
或 接收 SQL 查询结果时，用 map ，然后打断电调试可以看出具体当前 字段的子类型。
public class PhyOrderQO extends HmPhysicianVisitsOrdersDO implements Serializable {
/**
* 有效时长，秒数
*/
private BigInteger validTime;
public BigInteger getValidTime() {
return validTime;
}
public void setValidTime(BigInteger validTime) {
this.validTime = validTime;
}
}
延展
- mysql获得两个日期之间的时间差（年、月、天、时、分、秒）
