mybatis中SQL语句给boolean类型赋值问题

https://www.jb51.net/article/200546.htm

<if test="param2.ifRelease != null and param2.ifRelease != ''">
    and if_release = #{param2.ifRelease}
</if>

一样的问题，值ifRelease是Boolean类型，只有传true进入查询，传null及false都查询全部数据，所以判断需修改为

<if test="param2.ifRelease != null">
    and if_release = #{param2.ifRelease}
</if>

查询正常
