我收到此错误
[Doctrine\Common\Annotations\AnnotationException]
[Semantical Error] Couldn't find constant CJBusinessBundle:PO:new, method
CJ\BusinessBundle\Controller\ProductController::createAction().
我的注释部分
/**
* Creates a new Product entity.
*
* @Route("/", name="product_create")
* @Method("POST")
* @Template(CJBusinessBundle:PO:new.html.twig)
*/
我不明白这会有什么问题
