MyBatis-xml配置SQL文件中，传入List数组、基本类型String、int……、与自定义类型的方法

 //基本类型

     @Override
     public String queryItemNumber(String packId) throws Exception {
         // TODO Auto-generated method stub
         return dao.findForObject("SetMealMapper.queryItemNumber", packId).toString();
     }

 <select id="queryItemNumber" parameterType="String" resultType="int" >
         select count(1) from busi_repairpackage_detail where pak_m_id = #{packId}
     </select>

//List数组
/**
     * 保存套餐项目到Map数据库表
     * @param pd
     * @throws Exception
     */
    @Override
    public void saveRepairItemMap(List<BusiRepairPackageMap>  item_list) throws Exception {
        // TODO Auto-generated method stub
        dao.save("SetMealMapper.saveRepairItemMap", item_list);
    }

    <insert id="saveRepairItemMap" parameterType="java.util.List">
            insert into busi_repairpackage_detail (pak_m_id,item_id)
            values
        <foreach collection="list" item="item" index="index" separator=",">
            (#{item.pack_id},#{item.item_id})
        </foreach>
    </insert>

//自定义pd对象

    @Override
    public void updateRepairItemList(PageData pd) throws Exception {
        // TODO Auto-generated method stub
        dao.update("SetMealMapper.updateRepairItemList", pd);
    }

    <update id="updateRepairItemList"  parameterType="pd">
        update BUSI_REPAIRPACKAGE_INFO
        set pack_name = ${pack_name}
        ,pack_sort = ${pack_sort}
        where PAK_M_ID = ${pack_id} and GARAGE_ID = ${GARAGE_ID}
    </update>
