mybatis批量对象update更新，不推荐！

实际上是一条一条插入,不要用！更新了1331条数据， 用了5,6分钟，一条一条的入库，害。

serverImpl.java

太慢了，我就注释了。

mapper.java

mapper.xml

<!-- 更新箱数为null的数据 -->
     <update id="updatePoInfo"
        parameterType="com.kent.qr.vo.PoTableVO">
        update production_order
        set
        plant = #{plant},
        order_type = #{orderType},
        batch_no =#{batchNo},

        where
        production_order in(
        <foreach collection="poNoList" item="productionOrderNo"
            separator=",">
            #{productionOrderNo}
        </foreach>
        )

    </update> 
    

这个where条件，来源于PoTableVo实体类里面，在第一张图里add进去的。

     where
        production_order in(
        <foreach collection="poNoList" item="productionOrderNo"
            separator=",">
            #{productionOrderNo}
        </foreach>
        )
