主表批量维护从表--从表实现

一. mapper 批量维护实现：

<!-- 根据 Bid 批量新增 -->
<insert id="batchInsertByBid">
    insert into t_quote_(
        quote_type_,bid_id_,tender_id_,create_by_, attribute_name_,product_name_,product_type_,create_time_
    ) values
    <foreach collection="quoteList" item="item" separator=",">
        (1,#{bid.id},null,#{bid.createBy},#{item.attributeName},#{item.productName},#{item.productType},now())
    </foreach>
</insert>

<!-- 批量修改 -->
<update id="batchUpdateByList" parameterType="java.util.List">
    <foreach collection="quoteList" item="item" index="index" open="" close="" separator=";">
        update t_quote_
        <trim prefix="set" suffixOverrides=",">
            <if test='item.attributeName != null'>attribute_name_=#{item.attributeName,jdbcType=VARCHAR},</if>
            <if test='item.productName != null'>product_name_=#{item.productName,jdbcType=VARCHAR},</if>
            <if test='item.productType != null'>product_type_=#{item.productType,jdbcType=VARCHAR},</if>
        </trim>
        where id_ = #{item.id}
    </foreach>
</update>

<!-- 根据 Bid 批量删除 -->
<delete id="batchDeleteByBidIdAndIdNotIn">
    delete from t_quote_ 
    where quote_type_ = 1 and bid_id_ = #{bidId} 
    <if test="null != quoteList and quoteList.size > 0"> 
        and id_ not in
        <foreach collection="quoteList" item="item" open="(" separator="," close=")">
            #{item.id}
        </foreach>
    </if>
</delete>

<!-- 根据 Bid 批量全部删除 -->
<delete id="batchDeleteByBidIdAndIdNotIn">
    delete from t_quote_ 
    where quote_type_ = 1 and bid_id_ = #{bidId} 
</delete>

二. 接口层批量增删改申明

/**
 * 根据 Bid 批量新增
 * 
 * @param quoteList
 * @param bid
 * @return
 */
public int batchInsertByBid(@Param("quoteList") List<Quote> quoteList, @Param("bid") Bid bid);

/**
 * 批量修改
 * @param quoteList
 * @return
 */
public int batchUpdateByList(@Param("quoteList") List<Quote> quoteList);

/**
 * 根据 Bid 批量删除
 * @param quoteList
 * @param bidId
 * @return
 */
public int batchDeleteByBidIdAndIdNotIn(@Param("quoteList") List<Quote> quoteList, @Param("bidId") Long bidId);
    
/**
 * 根据 Bid 批量全部删除
 * @param bidId
 * @return
 */
public int batchDeleteByBidId(@Param("bidId") Long bidId);

三. 接口层批量维护实现，同时出现可能增删改的业务 （JDK8可以直接在 接口中写实现方法，用default申明即可）

/**
 * 通过暴力方式 <全部删除再全部新增> 批量维护
 * @param quoteList
 * @param bid
 */
public default void updateByBid(List<Quote> quoteList, Bid bid){    
    batchDeleteByBidId(bid.getId());
    if(quoteList.size() > 0)
        batchInsertByBid(quoteList, bid);
}

/**
 * 通过对比方式  <全部删除再全部新增> 批量维护 
 * @param updQuoteList
 * @param addQuoteList
 * @param bid
 */
public default void updateByBid(List<Quote> updQuoteList, List<Quote> addQuoteList, Bid bid){    
    batchDeleteByBidIdAndIdNotIn(bid.getId(), updQuoteList);    
    if(updQuoteList.size() > 0)
        batchUpdateByList(updQuoteList);    
    if(addQuoteList.size() > 0)
        batchInsertByBid(addQuoteList, bid);
}
