filter死循环

Question

public void doFilter(ServletRequest arg0, ServletResponse arg1,
FilterChain arg2) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest)arg0;
request.setCharacterEncoding("gb2312");
HttpServletResponse response = (HttpServletResponse)arg1;
String RequestUri = request.getRequestURI();
HttpSession session = request.getSession();
Object obj = session.getAttribute("user");
if(obj == null 
&& !RequestUri.endsWith("/index.jsp")){
System.out.println("非法操作，被过滤！");
response.sendRedirect(request.getContextPath()+"/"+this.forwradPath);
return;
}
arg2.doFilter(arg0, arg1);
} public void init(FilterConfig arg0) throws ServletException { this.filterConfig = arg0;
this.forwradPath = filterConfig.getInitParameter("forwradPath"); }
