String str = "^[0-9A-Za-z]{1-10}";
       String username = request.getParameter("username");
       if (username == str) {
           user.setUsername("username");
       }else {
           response.setCharacterEncoding("utf-8");
           PrintWriter out = response.getWriter();
           out.print
           ("<html>"
               +"<head>"
                   +"<meta http-equiv='Content-Type' content='text/html; charset=utf-8'/>"
               +"</head>"
               +"<script charset='utf-8' language='JavaScript' type='text/javascript'>alert('昵称格式错误，请重新输入');"
               +"window.location='register.jsp'</script>"
           +"</html>");
           out.flush();
           out.close();

}
