2.排查分析

DAO 接口及出入参定义：

1 List<TCoupon> batchSave(List<TCoupon> couponCodeList);

SQL 脚本中， <foreach> 标签 collection 属性给的变量名是与 DAO 接口入参一致的 “couponCodeList” 变量名，而不是固定变量 "list" 。问题就在这里。如下：

1 <insert id="batchSaveCouponCodeList" parameterType="java.util.List" useGeneratedKeys="true" keyProperty="couponId">
2     INSERT INTO
3         t_coupon (activity_id, coupon_code, use_status, create_user, create_time)
4     VALUES
5     <foreach collection="couponCodeList" item="item" index="index" separator=",">
6         (#{item.activityId}, #{item.couponCode}, 0, 'admin', NOW())
7     </foreach>
8 </insert>

3.解决方案

方案一）
批量插入 SQL 的 collection 属性给的入参对象变量名改成使用 "list" 变量名，<insert> 标签参数类型用 parameterType="java.util.List" 接收 DAO 接口中的参数集合。即可。

<insert id="batchSaveCouponCodeList" parameterType="java.util.List" useGeneratedKeys="true" keyProperty="couponId">
    INSERT INTO
        t_coupon (activity_id, coupon_code, use_status, create_user, create_time)
    VALUES
    <foreach collection="list" item="item" index="index" separator=",">
        (#{item.activityId}, #{item.couponCode}, 0, 'admin', NOW())
    </foreach>
</insert>

此方案的 DAO 接口无需使用 @Param 注解。

方案二）
批量插入 SQL 的 collection 属性给的入参对象变量名改成使用 "mylist" 变量名，<insert> 标签参数类型用 parameterType="java.util.List" 接收 DAO 接口中的参数集合。

<insert id="batchSaveCouponCodeList" parameterType="java.util.List" useGeneratedKeys="true" keyProperty="couponId">
    INSERT INTO
        t_coupon (activity_id, coupon_code, use_status, create_user, create_time)
    VALUES
    <foreach collection="mylist" item="item" index="index" separator=",">
        (#{item.activityId}, #{item.couponCode}, 0, 'admin', NOW())
    </foreach>
</insert>

DAO 接口入参使用 @Param 注解场景，入参别名使用 "mylist" 。即 DAO 接口入参与 SQL 入参名称一致且为 "mylist"。亦可。

List<TCoupon> batchSave(@Param("mylist") List<TCoupon> couponCodeList);
