使用取到bean:write的值，并赋值给java变量

<logic:iterate id="item" name="list" type="com.worthtech.app.bean.Expense" indexId="index">
				        <%
				        int i =((java.lang.Integer)pageContext.findAttribute("index")).intValue();
				      	if((i%2)==0){//斑马线
				        %>
				        	<tr class="SelcetOff">
				        <%}else{%>
				       		<tr class="SelcetOn">
				        <%}%>
				          <td><div align="center"><bean:write name="item" property="date"/></div></td>
				          <td><div align="center"><bean:write name="item" property="addtime"/></div></td>
				          
				           <bean:define id="var" name="item" property="addtime" type="java.lang.String"/>
				        	<%
				        	java.lang.String old=var;
