不得不感慨，解决问题的能力实在是弱爆了，一个这么小的问题，解决了好几天，本以为是框架出现了问题，又重新换了框架，没想到是这个问题
我写的是一个服装的网站，在后台需要添加产品，页面代码如下
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ page import="com.cloth.cache.PageProperties" %>
<%@ page import="com.cloth.cache.*,com.cloth.modelBase.PageListInfo,com.cloth.pojo.*" %>
<%
String path = request.getContextPath();
String context = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
PageProperties properties = new PageProperties();
List categoryList = ((PageListInfo)request.getAttribute("categoryListInfo")).getList();
Product product = null;
Category category = null;
%>

可是提交表单的时候返回的结果却总是input，无语了，到底是怎么回事啊？？？我用了无数的方法，就是找不出来，结果Google到了这篇文章<http://bbs.csdn.net/topics/350063386>,楼主的答案彻底把我杀死。我在页面要传递两个参数到后台，但是在select里面却无法实现，只好把它亲结成一个字符串进行传递，参数名称是categoryId,问题就出现在了这里，由于categoryId是Integer类型的，所以后台老是出现转换异常，但是控制台也不把这种异常打印出来，所以。。。。。
