Package top.tangyh.basic.database.mybatis.conditions.query

Class LbQueryWrap<T>

java.lang.Object
com.baomidou.mybatisplus.core.conditions.Wrapper<T>
com.baomidou.mybatisplus.core.conditions.AbstractWrapper<T,com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>,Children>
com.baomidou.mybatisplus.core.conditions.AbstractLambdaWrapper<T,LbQueryWrap<T>>
top.tangyh.basic.database.mybatis.conditions.query.LbQueryWrap<T>
Type Parameters:
T - 实体类型
All Implemented Interfaces:
com.baomidou.mybatisplus.core.conditions.interfaces.Compare<LbQueryWrap<T>,com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>>, com.baomidou.mybatisplus.core.conditions.interfaces.Func<LbQueryWrap<T>,com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>>, com.baomidou.mybatisplus.core.conditions.interfaces.Join<LbQueryWrap<T>>, com.baomidou.mybatisplus.core.conditions.interfaces.Nested<LbQueryWrap<T>,LbQueryWrap<T>>, com.baomidou.mybatisplus.core.conditions.ISqlSegment, com.baomidou.mybatisplus.core.conditions.query.Query<LbQueryWrap<T>,T,com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>>, Serializable
public class LbQueryWrap<T> extends com.baomidou.mybatisplus.core.conditions.AbstractLambdaWrapper<T,LbQueryWrap<T>> implements com.baomidou.mybatisplus.core.conditions.query.Query<LbQueryWrap<T>,T,com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>>
类似 LambdaQueryWrapper 的增强 Wrapper

相比 LambdaQueryWrapper 的增强如下：

%

where name like '%\%%' where name like '%\_%'

1，new LbQueryWrap(T entity)时， 对entity 中的string字段 %和_ 符号进行转义，便于模糊查询 2，对like方法的参数 %和_ 符号进行转义，便于模糊查询 3，对nested、eq、ne、gt、ge、lt、le、in、like 等方法 进行条件判断，null 或 "" 字段不加入查询 4，增加 leFooter 方法， 将日期参数值，强制转换成当天 23：59：59 5，增加 geHeader 方法， 将日期参数值，强制转换成当天 00：00：00
