尝试在 symfony 3.3 语法中捕获 orm 学说

Question

我正在尝试通过 try catch 在控制器中捕获 Doctrine 异常，我正在使用 Symfony 3

try {
   $em = $this->get('doctrine.orm.entity_manager');
   $em->persist( $transaction );
   $em->flush();
} catch(Exception $e) {
   return new JsonResponse(['error' => 'already exist']);
}

提前致谢

我终于找到了问题的解决方案，我想与您分享解决方案

try {
   $em = $this->get('doctrine.orm.entity_manager');
   $em->persist( $transaction );
   $em->flush();
} catch(\Doctrine\DBAL\Exception\UniqueConstraintViolationException $e) {
            throw new \Symfony\Component\HttpKernel\Exception\HttpException(409, "Transaction already exist" );
        } catch(\Doctrine\DBAL\Exception\ConstraintViolationException $e ) {
            throw new \Symfony\Component\HttpKernel\Exception\HttpException(409, "Bad request on Transaction" );
        } catch(\Doctrine\DBAL\Exception\TableNotFoundException $e ) {
            throw new \Symfony\Component\HttpKernel\Exception\HttpException(409, "Transaction Table not found" );
}
