java 代码

package com.bjjdsy.demo;

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.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class UserLoginFilter implements Filter{
    public void init(FilterConfig config)
    throws ServletException {
    }
    public void destroy() {}
    public void doFilter(ServletRequest request,
            ServletResponse response,
            FilterChain chain)
            throws ServletException, IOException
    {
        HttpServletRequest requ = (HttpServletRequest)request;
        String uri = ((HttpServletRequest)request).getRequestURI();
        if ((uri.trim().indexOf("login.do") == -1)&&(requ.getSession(false) == null))
        {
            HttpServletResponse res = (HttpServletResponse)response;
            res.sendRedirect(requ.getContextPath()+"/timeout.jsp");
        }
        else
        {
            chain.doFilter(request,response);
        }
    }


}
