运行结果是乱码现象如何解决

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！！！
