public class FilterValet  implements Filter {
 private FilterConfig filterConfig = null;
  private String encoding = null;   //默认构造函数
  public FilterValet() {
  }   //初始化过滤器
  public void init(FilterConfig filterConfig) throws ServletException {
    this.filterConfig = filterConfig;
   
  }
  //执行过滤操作
  public void doFilter(ServletRequest request, ServletResponse response,
                       FilterChain filterChain) throws
    IOException, ServletException {
   

HttpServletRequest servletRequest = (HttpServletRequest) request;        HttpServletResponse servletResponse = (HttpServletResponse) response;        HttpSession session = servletRequest.getSession();
         String user=(String)servletRequest.getSession().getAttribute("purviews"); //获取purviews权限内空
        // String user=(String)session.getAttribute("user");
     System.out.println("NEW_seesion_purviews="+user);
   //  String url = servletRequest.getRequestURI();
     //System.out.println("url="+url);
    // String isLog = (String) servletRequest.getSession().getAttribute("isLog");
    // System.out.println("isLog = " + isLog);        
     if (user == null) {      //根据purviews权限内空设定内容（自定义），             servletResponse.sendRedirect("/admin/login.jsp");//如果purviews有无内容则进入登陆页         }else {          filterChain.doFilter(request, response); ;//如果purviews有内容则放行，进入下一步操作         }
  }   public void destroy() {
    filterConfig = null;
