表单提交中文至Servlet乱码
环境：NetBeans + JDK1.6
源代码：
index.jsp
<HTML>
<HEAD>
<TITLE> TEST </TITLE>
</HEAD>
<BODY>
<FORM METHOD=GET ACTION= "/Servlet/Hello ">
<INPUT TYPE=TEXT NAME= "name " > <P>
<INPUT TYPE=SUBMIT>
</FORM>
</BODY>
</HTML>
Hello.JAVA
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Hello extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType( "text/html;charset=UTF-8 ");
res.setHeader( "Content-language ", "zh ");
PrintWriter out = res.getWriter();
//String name = req.getParameter( "name ")
String name =new String(req.getParameter( "name ").getBytes( "iso-8859-1 "), "UTF-8 ");
out.println( " <HTML> ");
out.println( " <HEAD> <META content=text/html; charset=gb2312 http-equiv=Content-Type> </HEAD> ");
out.println( " <BODY> ");
out.println( "你好, " + name);
out.println( " </BODY> </HTML> ");
}
public String getServletInfo() {
return "A servlet that knows the name of the person to whom it 's " +
"saying hello ";
}
}
也看了之前不少朋友关于乱码的文章，可是一直没有解决
上面的程序用POST方法则一点问题也没有，用GET方法就是乱码
我是个超级新手，基本上啥也不会，过滤器也不知道怎么加进去~~
还是NETBEANS5.5的傻瓜环境
请教~~
------解决方案--------------------
写一个filter，在其doFilter(ServletRequest request, ServletResponse response, FilterChain chain) 方法中调用request.setCharacterEncoding( "GB2312 ");
package com.forecast.filter;
