程序包 top.tangyh.basic.database.mybatis.conditions.query

类 LbqWrapper<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,LbqWrapper<T>>
top.tangyh.basic.database.mybatis.conditions.query.LbqWrapper<T>
所有已实现的接口:
com.baomidou.mybatisplus.core.conditions.interfaces.Compare<LbqWrapper<T>,com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>>, com.baomidou.mybatisplus.core.conditions.interfaces.Func<LbqWrapper<T>,com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>>, com.baomidou.mybatisplus.core.conditions.interfaces.Join<LbqWrapper<T>>, com.baomidou.mybatisplus.core.conditions.interfaces.Nested<LbqWrapper<T>,LbqWrapper<T>>, com.baomidou.mybatisplus.core.conditions.ISqlSegment, com.baomidou.mybatisplus.core.conditions.query.Query<LbqWrapper<T>,T,com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>>, Serializable
public class LbqWrapper<T> extends com.baomidou.mybatisplus.core.conditions.AbstractLambdaWrapper<T,LbqWrapper<T>> implements com.baomidou.mybatisplus.core.conditions.query.Query<LbqWrapper<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： 1，new QueryWrapper(T entity)时， 对entity 中的string字段 %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，对*like*相关方法的参数 %和_ 符号进行转义，便于模糊查询 5，增加 leFooter 方法， 将日期参数值，强制转换成当天 23：59：59 6，增加 geHeader 方法， 将日期参数值，强制转换成当天 00：00：00
