MyBatis-Plus 功能增强，查询时直接转换为VO减少mapstruct的依赖

请详细描述需要增加的功能 增加查询时直接获取转换后的类,代码如下 package com.foxfunds.common.mybatis.core.mapper;

import cn.hutool.core.collection.CollUtil; import cn.hutool.core.util.ObjectUtil; import com.baomidou.mybatisplus.core.conditions.Wrapper; import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper; import com.baomidou.mybatisplus.core.mapper.BaseMapper; import com.baomidou.mybatisplus.core.metadata.IPage; import com.baomidou.mybatisplus.core.toolkit.ReflectionKit; import com.baomidou.mybatisplus.extension.plugins.pagination.Page; import com.baomidou.mybatisplus.extension.toolkit.Db; import com.foxfunds.common.core.utils.BeanCopyUtils; import org.apache.ibatis.logging.Log; import org.apache.ibatis.logging.LogFactory;

import java.io.Serializable; import java.util.Collection; import java.util.List; import java.util.Map;
