protected void doGet(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, IOException {
String name=request.getParameter("username");//获得用户名
String password=request.getParameter("password");//获得密码
String success="登录成功收到数据";
if(name.equals("admin")&password.equals("admin")){//判断
System.out.println("登录成功");
}else {
System.out.println("密码或用户名不正确");
}
}
