施用ibatis防止sql注入

使用ibatis防止sql注入
为了防止SQL注入，iBatis模糊查询时也要避免使用$$来进行传值。下面是三个不同数据库的ibatis的模糊查询传值。

    mysql: select * from stu where name like concat('%',#name #,'%')           oracle: select * from stu where name like '%'||#name #||'%'          SQL Server:select * from stu where name like '%'+#name #+'%   

如：

<!-- 用途：小二后台查询活动的数目 -->	<!-- 频率：1000/天 -->	<!-- 维护：刘飞 -->	<select id="countActivitySearch" resultClass="java.lang.Long" parameterClass="actDO">    	<![CDATA[    		select count(id) from activity     		]]>    	    	<dynamic prepend="WHERE">			<isNotNull prepend=" AND " property="name">                name LIKE CONCAT('%', #name#, '%')            </isNotNull>            <isNotNull prepend=" AND "  property="itemId">            	itemId = #itemId#            </isNotNull>            <isNotNull prepend=" AND " property="itemName">                itemName LIKE CONCAT('%', #itemName#, '%')            </isNotNull>                     <isNotNull prepend=" AND " property="status">                status = #status#            </isNotNull>             <isNotNull prepend=" AND " property="actStatus">                actStatus = #actStatus#            </isNotNull>                      <isNotNull prepend=" AND " property="domain">                domain LIKE CONCAT('%', #domain#, '%')            </isNotNull>		</dynamic>		    </select>        <!-- 用途：小二后台查询活动的列表 -->	<!-- 频率：1000/天 -->	<!-- 维护：刘飞 -->    <select id="searchActivityForList" resultMap="actResult" parameterClass="actDO">    	<![CDATA[    		select * from activity     	]]>    	    	<dynamic prepend="WHERE">			<isNotNull prepend=" AND " property="name">                name LIKE CONCAT('%', #name#, '%')            </isNotNull>            <isNotNull prepend=" AND "  property="itemId">            	itemId = #itemId#            </isNotNull>            <isNotNull prepend=" AND " property="itemName">                itemName LIKE CONCAT('%', #itemName#, '%')            </isNotNull>                     <isNotNull prepend=" AND " property="status">                status = #status#            </isNotNull>             <isNotNull prepend=" AND " property="actStatus">                actStatus = #actStatus#            </isNotNull>                      <isNotNull prepend=" AND " property="domain">                domain LIKE CONCAT('%', #domain#, '%')            </isNotNull>		</dynamic>            	<![CDATA[    		order by starttime desc, createtime desc    	    limit         		#startRow#, #perPageSize#	        ]]>    </select>

不要这样来写：

<select id="searchActivityForCount" resultClass="java.lang.Long" >    	<![CDATA[    		select count(*) from activity    		]]>    	    	<dynamic prepend="WHERE">			<isNotNull prepend=" AND " property="name">                name LIKE '%$name$%'            </isNotNull>			<isNotNull prepend=" AND " property="itemId">                itemId LIKE '%$itemId$%'            </isNotNull>            <isNotNull prepend=" AND " property="itemName">                itemName LIKE '%$itemName$%'            </isNotNull>                     <isNotNull prepend=" AND " property="status">                status = #status#            </isNotNull>             <isNotNull prepend=" AND " property="actStatus">                actStatus = #actStatus#            </isNotNull>                      <isNotNull prepend=" AND " property="domain">                domain LIKE '%$domain$%'            </isNotNull>		</dynamic>    </select>        <select id="searchActivityForList" resultMap="actResult" parameterClass="actDO">    	<![CDATA[    		select * from activity     	]]>    	    	<dynamic prepend="WHERE">			<isNotNull prepend=" AND " property="name">                name LIKE '%$name$%'            </isNotNull>			<isNotNull prepend=" AND " property="itemId">                itemId LIKE '%$itemId$%'            </isNotNull>            <isNotNull prepend=" AND " property="itemName">                itemName LIKE '%$itemName$%'            </isNotNull>                     <isNotNull prepend=" AND " property="status">                status = #status#            </isNotNull>             <isNotNull prepend=" AND " property="actStatus">                actStatus = #actStatus#            </isNotNull>                      <isNotNull prepend=" AND " property="domain">                domain LIKE '%$domain$%'            </isNotNull>		</dynamic>            	<![CDATA[    		order by starttime desc, createtime desc    	    limit         		#startRow#, #perPageSize#	        ]]>    </select>
