Mybatis批量更新和插入

先看批量更新代码,返回值resultType=‘int’可以不用声明

XML如下

<update id="batchUpdatepdateBankCreditDetail" parameterType="java.util.List">
update ASSET_BANK_CREDIT_DETAIL
<trim prefix="set" suffixOverrides=",">
<trim prefix="BILL_ID = case id" suffix="end,">
<foreach collection="list" item="item" index="index">
<if test="item.billId != null and item.billId != '' ">
when #{item.id} then #{item.billId}
</if>
</foreach>
</trim>
<trim prefix="CARD_ID = case id" suffix="end,">
<foreach collection="list" item="item" index="index">
<if test="item.cardId != null and item.cardId != '' ">
when #{item.id} then #{item.cardId}
</if>
</foreach>
</trim>
<trim prefix="MEDIUM_NO = case id" suffix="end,">
<foreach collection="list" item="item" index="index">
<if test="item.mediumNo != null and item.mediumNo != '' ">
when #{item.id} then #{item.mediumNo}
</if>
</foreach>
</trim>
MODIFY_DATE = now()
</trim>
where id in
<foreach collection="list" separator="," item="item" index="index" open="(" close=")">
#{item.id}
</foreach>
</update>

java接口

/**
* 批量更新
* @param updateList
*/
int batchUpdatepdateBankCreditDetail(List<AssetBankCreditDetailPO> updateList);

再来看批量插入

<!-- 批量插入 -->
<insert id="batchInsertBankCreditDetail" parameterType="java.util.List" >
INSERT INTO ASSET_BANK_CREDIT_DETAIL (<include refid="Base_Column_List" />)
VALUES
<foreach collection="list" item="item" index="index" separator=", ">
(
sys_guid(),
#{item.billId},
#{item.clientNo},
#{item.mediumNo},
#{item.accountDate},
#{item.tradeType},
#{item.consumerCategory},
#{item.tradeTarget},
#{item.balanceCurrency},
#{item.income},
#{item.expense},
#{item.tradeCurrency},
#{item.tradeTime},
#{item.balance},
#{item.channelSource},
#{item.remark},
#{item.createBy},
now(),
#{item.modifyBy},
now(),
#{item.cardId}
)
</foreach>
</insert>

java Mapper接口 返回值为插入条数，XML中可以不写resultType=‘int’，接口也可以拿到返回值

int batchInsertBankCreditDetail(List<AssetBankCreditDetailPO> list);
