关于批量插入一组数据

批量插入输入，参数的类型为 resultMap中的形式

id是接口方法名

parameterType是参数类型，解析见关于parameterType的解释

keyProperty是Pojo中Java 实体类对象的属性名（keyproperty指明数据库中返回的主键id给实体类中的哪个属性）

useGeneratedKeys =true 这个表示插入数据之后 返回 一个自增的主键id给你对应实体类中的主键属性

<insert id="insertBatch" parameterType="CerComponent" useGeneratedKeys="true" keyProperty="id" >
        insert into cer_book_component(id,book_id,cmpt_name,work_name,rate_time,real_time,count_down,cmpt_type,cmpt_left,cmpt_top,
        cmpt_width,cmpt_height,cmpt_line,cmpt_operator,cmpt_role,cmpt_user,num_begin,num_end,is_equal_begin,is_equal_end,num_point,
        font_size,font_name,file_path,is_required) values
        <foreach item="item" collection="list" separator=",">
            (#{item.id},#{item.bookId},#{item.cmptName},#{item.workName},#{item.rateTime},#{item.realTime},#{item.countDown},#{item.cmptType},
            #{item.cmptLeft},#{item.cmptTop},#{item.cmptWidth},#{item.cmptHeight},#{item.cmptLine},#{item.cmptOperator},#{item.cmptRole},
            #{item.cmptUser},#{item.numBegin},#{item.numEnd},#{item.isEqualBegin},#{item.isEqualEnd},#{item.numPoint},
            #{item.fontSize},#{item.fontName},#{item.filePath},#{item.isRequired})
        </foreach>

    </insert>
