使用<bean:define >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
