代码如下：

package servlet;

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 tools.DebugPrintf;

public class WanJiaExitSystem extends HttpServlet {

	/**
	 * Constructor of the object.
	 */
	public WanJiaExitSystem() {
		super();
	}

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		doPost(request, response);
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		
		String msg=String.format("来源地址："+request.getHeader("referer"));
		DebugPrintf.Printf(msg);
		
		request.getSession().removeAttribute("wanjia");
			
			//servlet跳出frameset框架
			//out.println("<script>window.parent.location.href('/index.html')</script>");
			PrintWriter out = response.getWriter();
			String url="<script>window.parent.location.href('";
			url+=request.getContextPath();
			url+="/index.html')</script>)";
			DebugPrintf.Printf(url);
			out.println(url);
	}
