使用action属性接收参数，中文问题
客户端JSP请求（这里可能输入的是中文，所以可能就会出现乱码问题）
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <base href="<%=basePath%>"> <title>My JSP 'index.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--> </head> <body>使用action属性接收参数，测试中文问题<form action="user/User_add" method="post">姓名：<input type="text" name="name"></input><input type="submit" value="submit"/></form> </body></html>?现在要看的是web.xml因为用户一发送请求就先到web.xml，web.xml过滤所有的用户请求(看注释)
