1、首先在前端页面添加勾选框（name设置为check）

2、mybatis代码

1. 当check勾选时，check不为null，走模糊查询like
2. 当check未勾选时，check为null，走精准查询 = 

            <if test="check != null and check !='' "><if test="kuangjia != null and kuangjia != ''">AND kuangjia like concat('%',#{kuangjia},'%')</if><if test="dianji != null and dianji != ''">AND dianji like concat('%',#{dianji},'%')</if></if>	<if test="check == null or check == '' "><if test="kuangjia != null and kuangjia != ''">AND kuangjia = #{kuangjia}</if><if test="dianji != null and dianji != ''">AND dianji = #{dianji}</if></if>
