无法从NetBeans连接到MySQL

Question

public function __construct($request)
{
    //
    $this->request = $request;
    $this->to($request->email, $request->name);
    $this->subject('Email Notification on offer');
    $this->attach('path_to_pdf_file', array(
        'as' => 'pdf-report.zip', 
        'mime' => 'application/pdf')
    );
}

我试图找到解决方案，但找不到。我安装了Net Bean 8.2和MySQL 8.0。我也将jconnector连接到了投影仪，但是仍然无法连接到数据库。请帮忙.............以上是我得到的错误。
