Symofny3.0 Doctrine 操作

Symofny3.0 Doctrine 操作

• 配置数据库链接

//app/config/parameters.yml
parameters:
database_driver: pdo_mysql
database_host: 127.0.0.1
database_port: 3306
database_name: symfonty
database_user: root
database_password: 123456
secret: ThisTokenIsNotSoSecretChangeIt

> 在命令行中执行下面命令测试是否连接成功(创建数据库和表)
>  php bin/console doctrine:database:create
>  php bin/console doctrine:schema:update --force


* 在AppBundle 新建Entity文件夹用来创建数据库的字段
     namespace AppBundle\Entity;         
     use Doctrine\ORM\Mapping as ORM;
     /**
      * @ORM\Entity
      * @ORM\Table(name="wechatevent")
      */
     class WechatEvent{
         /**
          * @ORM\Column(type="integer")
          * @ORM\Id
          * @ORM\GeneratedValue(strategy="AUTO")
          */
         private $id;
     
         /**
          * @ORM\Column(type="string", length=100)
          */
         private $toUserName;
     
         /**
          * @ORM\Column(type="string", length=100)
          */
         private $fromUserName;
     
     
     }

 // 创建了3个字段id，toUserName， formUserName


* 为这3 个字段添加get set 属性，来操作增删查改
>  $php bin/console doctrine:generate:entities AppBundle


* 在control创建路由测试


 ``` php
 namespace AppBundle\Controller;
 
 use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
 use Symfony\Bundle\FrameworkBundle\Controller\Controller;
 use Symfony\Component\HttpFoundation\Request;
 use AppBundle\Entity\WechatEvent;
 use Symfony\Component\HttpFoundation\Response;
 
 class DefaultController extends Controller
 {
     /**
      * @Route("/", name="homepage")
      */
     public function indexAction()
     {
         $msg = new WechatEvent();
         $msg->setToUserName('nick');
         $msg->setFromUserName('nickback');
         $em = $this->getDoctrine()->getManager();
         $em->persist($msg);
         $em->flush();
         return new Response("done");
 
     }
 
 
 }
 ```
