运行结果是乱码现象如何解决

[IT小霸王]

package com.javastudy;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

public class SessionServlet extends HttpServlet
{
@Override
protected void service(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/html; charset = UTF-8");

PrintWriter out = response.getWriter();

HttpSession session = request.getSession();

session.setMaxInactiveInterval(60*60*24);

if(session.isNew())
{
session.setAttribute("session", "宇宙");

out.println("新会话已经建立！");
}
else
{
out.println("回话属性值：" + session.getAttribute("session"));
}
}
}

此程序运行后结果是乱码，在网上找了一个解决方案说是：在tomcat安装目录下面的server.xml文件中
<Connector connectionTimeout="20000" port="8080" URIEncoding="UTF-8" protocol="HTTP/1.1" redirectPort="8443"/>
URIEncoding即为tomcat的url编码方式，设置成为utf-8即可正常编码带中文的连接。但是我照做后还是乱码，尼玛，就崩溃了。哪位大牛指点一下！！！

request.setCharacterEncoding("UTF-8");
		response.setCharacterEncoding("UTF-8");

URIEncoding是指浏览器里面的那个地址编码

[nickpro]

修改编码格式为UTF-8

[编程点滴]

request.setCharacterEncoding("UTF-8");

为什么每天都有问编码的问题，不是已经有太多人问过，太多回答吗
