mybatis 批量进行插入更新，数据库为postgreSQL？

这么会没有批量更新呢？

<update id="updateBatch" parameterType="java.util.List">
    update mydata_table 
    set  status=
    <foreach collection="list" item="item" index="index" 
        separator=" " open="case ID" close="end">
        when #{item.id} then #{item.status}
    </foreach>
    where id in
    <foreach collection="list" index="index" item="item" 
        separator="," open="(" close=")">
        #{item.id,jdbcType=BIGINT}
    </foreach>
 </update>

另外感觉mybatis plus 更好一些：http://mp.baomidou.com/
