MyBatis 批量执行 SQL 语句出错

问题

  MyBatis 批量 update 更新数据时，SQL 语句并没有错，但还报错， SQL 语句如下：

    <!-- 批量更新，通过接收传进来的参数list进行循环着组装sql -->
    <update id="updateListOther" parameterType="java.util.List">
        <foreach collection="list" item="value" index="index" open="" close="" separator=";">
            update picture_bed.other set content = #{value.content} where id = #{value.id}
        </foreach>
    </update>

解决方法

  在连接数据库的 url 后边加上 &allowMultiQueries=true 就 OK 了。

jdbc:mysql://localhost:3306/picture_bed?serverTimezone=GMT%2B8&useSSL=false&serverTimezone=UTC&allowMultiQueries=true
