mybatis 標籤記錄

1. mysql數據庫（其他數據庫就不知道了）插入一個對象時返回主鍵

   <insert id="addShareActivity" parameterType="com.luolai.ec.model.activity.ShareActivityVO"
   	useGeneratedKeys="true" keyProperty="id">
   		<![CDATA[
   			insert into 
   			as_activity_share(user_id,user_name,level_name,
   			create_date,content,image_path,good_count,
   			is_check,integral,site_id,comment_count,activity_id,type) 
   			values(
   			#{userId},#{userName},#{levelName},#{createDate},
   			#{content},#{imagePath},#{goodCount},
   			#{isCheck},#{integral},#{siteId},#{commentCount},#{activityId},#{type}
   			)
   		]]>
   	</insert>

   useGeneratedKeys="true"    表示返回主鍵

   keyProperty="id"           表示返回的值爲對象 id 字段

   		WHERE id in
   		<foreach item="messageId" index="index" collection="list" open="(" close=")" separator=",">
   			#{messageId}
   		</foreach>
   		
   	</update>

2. 設置 延遲加載<pre name="code" class="html"><configuration>
