JSP编码问题!实在没办法了!!!!
<%@ page contentType= "text/html;charset=GB2312 " pageEncoding= "GBK "%>
<html>
<head>
</head>
<body>
<form method= "post " action= "session2.jsp " >
请输入姓名 <input type= "text " name= "username ">
<input type= "submit " value= "submit ">
</form>
</body>
</html>
页面二:
<%@ page contentType= "text/html;charset=GB2312 " pageEncoding= "GBK " %>
<html>
<head>
</head>
<body>
<%@ page language= "java " %>
<%! String name= " "; %>
<p>
<%
name=request.getParameter( "username ");
session.putValue( "username ",name);
%>
您的姓名是: <%=name %>
<form method= "post " action= "session3.jsp ">
您最喜欢的水果: <input type= "text " name= "fruit ">
<input type= "submit " name= "submit ">
</form>
</body>
</html>
英文没问题! 中文一旦输入就是出现问号之类的乱码 困扰好久了!
页面三:
<%@ page language= "java " import= "java.util.* " pageEncoding= "GBK "%>
<%@ page contentType= "text/html;charset=GB2312 " %>
<%
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 'session3.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>
<%
String fruit=request.getParameter( "fruit ");
session.putValue( "fruit ", "name ");
String a=(String)session.getValue( "username ");
%>
<%= "您最喜欢的水果 "+fruit %> <br>
<%= "您的名字是 "+a %>
</body>
</html> 我
我的开发环境是 Eclipse+Myeclipse+tomcat
[解决办法]
lz在页面二和页面三的 <% request.getParameter( "username "); %> 之前加上：
<% request.setCharacterEncoding( "GBK "); %> 试试。
