代码如下

复制代码

**mapper**
void publishArticleFiles(@Param("list") List<BaseUserArticlesFiles> list);
**xml**
    <insert id="publishArticleFiles" >
        insert into base_user_articles_files(
        <if test="userArticlesId != null and userArticlesId != ''">user_articles_id,</if>
        <if test="fileUrl != null and fileUrl != ''">file_url,</if>
        <if test="isDelete != null and isDelete != ''">is_delete,</if>
        )values(
        <foreach collection="list" item="item" separator=",">
            <if test="userArticlesId != null and userArticlesId != ''">#{item.userArticlesId},</if>
            <if test="fileUrl != null and fileUrl != ''">#{item.fileUrl},</if>
            <if test="isDelete != null and isDelete != ''">#{item.isDelete},</if>
        </foreach>
        )
    </insert>

问题原因

1、在批量插入的中直接使用了字段名（如userArticlesId）而非列表项对象属性

2、动态SQL的判断未正确关联到列表项对象

3、VALUES部分的拼接语法错误（逗号位置不正确）

修改后的代码如下

bash 复制代码

    <insert id="publishArticleFiles">
        <if test="list != null and !list.isEmpty()">
            INSERT INTO base_user_articles_files(
            user_articles_id,
            file_url,
            is_delete
            ) VALUES
            <foreach collection="list" item="item" separator=",">
                (
                #{item.userArticlesId},
                #{item.fileUrl},
                #{item.isDelete}
                )
            </foreach>
        </if>
    </insert>
