    public class FilterOne implements Filter{
    public void doFilter(ServletRequest req,ServletResponse res,FilterChain cha )throws IOException,ServletException{
    HttpServletRequest httpreq=(HttpServletRequest) req;
    HttpServletResponse httpResponse=(HttpServletResponse)res;
    Map<String, String> Usermap=new HashMap<String, String>();
    Usermap.put("name","admin");
    Usermap.put("pass","123");
    PrintWriter out=httpResponse.getWriter();
    String []name=httpreq.getParameterValues("name");//获取用户名和密码
    String []pass=httpreq.getParameterValues("pass");//
    if((name!=null&&pass!=null)&&(!name.equals("")&&!pass.equals(""))){
    if(name.equals("admin")){
    if (pass.equals("123")) {
    out.println("登陆成功");
    }else {
    out.println("密码错误");
    }
    }else{
    out.println("该用户不存在");
    }
    }
    }
    public void init(FilterConfig arg0) throws ServletException{
    System.out.println("Filter初始值");
    }
    @Override
    public void destroy() {
    System.out.println("Filter销毁");
    }
    }
