批量插入

• 方式一 insert all into table(...) values(...) into table(...) values(...) select * from dual;

<insert id="addList" parameterType="java.util.List" useGeneratedKeys="false">
        INSERT ALL
        <foreach item="item" index="index" collection="list">
        INTO T_APPLAUD
        (
            ID,
            USER_ID,
            BUSINESS_TYPE,
            PRODUCT_ID,
            CREATE_TIME
        ) VALUES
        (
            #{item.id, jdbcType=NUMERIC},
            #{item.userId, jdbcType=VARCHAR},
            #{item.businessType, jdbcType=VARCHAR},
            #{item.productId, jdbcType=VARCHAR},
            #{item.createdTime, jdbcType=NUMERIC}
        )
        </foreach>
        SELECT 1 FROM DUAL
    </insert>

• 方式二 insert into table(...) (select ... from dual) union all (select ... from dual)

<insert id="addList" parameterType="java.util.List" useGeneratedKeys="false">
        INSERT INTO T_APPLAUD
        (
            ID,
            USER_ID,
            BUSINESS_TYPE,
            PRODUCT_ID,
            CREATE_TIME
        )
        <foreach item="item" index="index" collection="list" separator="union all">
        (
            SELECT
                #{item.id},
                #{item.userId},
                #{item.businessType},
                #{item.productId},
                #{item.createdTime}
            FROM DUAL
        )
        </foreach>
