thinkphp,该如何处理

thinkphp
我在练习某个thinphp实战项目,是学籍管理系统,后台登陆跳转无法从登陆页面跳转到管理页面 不知道为什么!
登陆form "

"
admin控制器
namespace Home\Controller;
use Think\Controller;
class AdminController extends Controller {

public function index() {
$this->display("index"); //显示管理员主界面

}
}
?>

就出现这样的
无法加载模块:Admin

ThinkPHP3.2.1 { Fast & Simple OOP PHP Framework } -- [ WE CAN DO IT JUST THINK ]

------解决思路----------------------
class AdminController extends Controller {

admin/index" method="post">
改为
Admin/index" method="post">
