自己写一个过滤器 也能实现你想要的功能 和我以前做的一个项目有些相象 给你段代码过滤器类：
package com.neusoft.icd.common;import java.io.IOException;import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;public class DecodeServlet extends HttpServlet implements Filter {
private FilterConfig filterConfig;
private String charSet = null;
//Handle the passed-in FilterConfig
public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;
charSet = this.filterConfig.getInitParameter("charset");
}
//Process the request/response pair public void doFilter(
ServletRequest request,
ServletResponse response,
FilterChain filterChain)
throws ServletException, IOException { //类型转换
HttpServletRequest myrequest = (HttpServletRequest) request;
//类型转换
HttpServletResponse myresponse = (HttpServletResponse) response;
//取得session
HttpSession session = myrequest.getSession();
String path = myrequest.getRequestURI(); //如果用户不是通过正常登陆访问页面，则将其转到错误页面
if (!(("1".equals(session.getAttribute("ISUSER")))
|| ("/WebMail/index.jsp".equals(path))
|| ("/WebMail/index.do".equals(path))
|| ("/WebMail/modifypassword.jsp".equals(path))
|| ("/WebMail/modifypassword.do".equals(path)))) {
//设置session里的值，以便可以进入错误页面，不会死循环
//session.setAttribute("ISUSER", "1"); myresponse.sendRedirect("/WebMail/index.jsp");
Common.debug(path); }
request.setCharacterEncoding(charSet); //  filterChain.doFilter(request, response);
}
//Clean up resources
public void destroy() {
}

</web-app>其中过滤器中的逻辑判断部分 你可以根据自己项目的需要改动 就可实现你要的功能了 不知道我这样说你是否明白
