mybatis 批量插入/批量修改的写法

1、jdbc链接修改

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true&rewriteBatchedStatements=true
jdbc.username=root
jdbc.password=root

2、批量插入

     <insert id="INSERT_BATCH_HOTEL_REAL_PRICE" parameterType="java.util.List">
        INSERT IGNORE INTO VST_HOTEL_REAL_TIME_PRICE ( 
            PRODUCT_ID, 
            REAL_TIME_PRICE1, 
            REAL_TIME_PRICE2, 
            REAL_TIME_REMAIN1, 
            REAL_TIME_REMAIN2,
            UPDATE_TIME
        ) VALUES
        <foreach collection="list" item="item" index="index" separator=",">
            (#{item.productId}, 
             #{item.realTimePrice1}, 
             #{item.realTimePrice2}, 
             #{item.realTimeRemain1}, 
             #{item.realTimeRemain2},NOW())
        </foreach>
     </insert>

3、批量修改

     <update id="UPDATE_HOTEL_REAL_TIME_PRICE" parameterType="java.util.List">
        <foreach collection="list" item="item" index="index" separator=";">
            UPDATE VST_HOTEL_REAL_TIME_PRICE
            <set>
                <if test="item.realTimePrice1 != null">
                    REAL_TIME_PRICE1 = #{item.realTimePrice1},
                </if>
                <if test="item.realTimePrice2 != null">
                    REAL_TIME_PRICE2 = #{item.realTimePrice2},
                </if>
                <if test="item.realTimeRemain1 != null">
                    REAL_TIME_REMAIN1 = #{item.realTimeRemain1},
                </if>
                <if test="item.realTimeRemain2 != null">
                    REAL_TIME_REMAIN2 = #{item.realTimeRemain2},
                </if>
                UPDATE_TIME = NOW()
            </set>
            WHERE PRODUCT_ID = ${item.productId}
         </foreach>
     </update>
