php - 找不到xxxxBundle\Entity\BookPermit对象。 (404未找到)-symfony

我有一个相关的表，如下图所示。
图书许可证

id | userfk  | bookfk   |
1  | 6       | 6        |
2  | 6       | 7        |
3  | 7       | 7        |
4  | 8       | 8        |

书

id | name  | uerfk   |
1  | xyz1   | 6       |
2  | xyz2   | 7       |
3  | xyz3   | 8       |

用户

id | email | phone |
6  | xyz   | xyz   |
7  | xyz   | xyz   |
8  | xyz   | xyz   |

现在我想从users表和bookpermit表中找到相应参数的地方获取图书的结果。books表与带有外键的users表相关。bookpermit表与books表的外键相关。
这是图书许可证的代码片段

/**
     * @var integer
     *
     * @ORM\Column(name="usersfk", type="integer")
     */
    private $usersfk;

                //getters and setters apply


    /**
     * @var integer
     *
     * @ORM\Column(name="permitid", type="integer")
     */
    private $permitid;

                //getters and setters apply



    // +++++++++++++++++1 relationship mapping between BookPermit and Users ++++++++++++++++++++ //
    //weak enity: book_permit can belong to different users
    /**
     * @ORM\ManyToOne(targetEntity="Users", inversedBy="book_permit")
     * @ORM\JoinColumn(name="usersfk", referencedColumnName="id")
     */
    private $userspermit;


    /**
     * Set Users
     *
     * @param \xxxBundle\Entity\Users $userspermit
     * @return
     */
    public function setUsersPermit(\xxxxBundle\Entity\Users $userspermit = null)
    {
        $this->userspermit = $userspermit;

        return $this;
    }

    /**
     * Get Users
     *
     * @return \xxxxBundle\Entity\Users
     */
    public function getUsersPermit()
    {
        return $this->userspermit;
    }





    // +++++++++++++++++1 relationship mapping between BookPermit and Books ++++++++++++++++++++ //
    //weak enity: bookpermit can belong to different books
    /**
     * @ORM\ManyToOne(targetEntity="bookpermit", inversedBy="book_book_permit")
     * @ORM\JoinColumn(name="bookfk", referencedColumnName="usersfk")
     */
    private $bookpermit;


    /**
     * Set Books
     *
     * @param \xxxxBundle\Entity\Books $bookpermit
     * @return
     */
        public function setBookPermit(\xxxBundle\Entity\Books $bookpermit = null)
    {
        $this->bookpermit = $bookpermit;

        return $this;
    }

    /**
     * Get Books
     *
     * @return \xxxxBundle\Entity\Books
     */
    public function getBooksPermit()
    {
        return $this->bookpermit;
    }

下面是books实体的代码片段

/**
     * @var integer
     *
     * @ORM\Column(name="usersfk", type="integer")
     */
    private $usersfk;

    //getters and setters apply here


// +++++++++++++++++1 relationship mapping between Books and Users ++++++++++++++++++++ //
    //weak enity: many books can belong to a user
    /**
     * @ORM\ManyToOne(targetEntity="Users", inversedBy="books")
     * @ORM\JoinColumn(name="usersfk", referencedColumnName="id")
     */
    private $users;


    /**
     * Set Users
     *
     * @param \xxxxBundle\Entity\Users $users
     * @return
     */
    public function setUsers(\xxxxBundle\Entity\Users $users = null)
    {
        $this->users = $users;

        return $this;
    }

    /**
     * Get Users
     *
     * @return \xxxxBundle\Entity\Users
     */
    public function getUsers()
    {
        return $this->users;
    }


    // +++++++++++++++++1 relationship mapping between Books and  BookPermit ++++++++++++++++++++ //
    //
    //super entity: one user can have different book
    /**
     * @ORM\OneToMany(targetEntity=BookPermit", mappedBy="bookpermit")
     */
    private $book_book_permit;

    /**
     * Add BookPermit
     *
     * @param \xxxxBundle\Entity\BookPermit $book_book_permit
     * @return BookPermit
     */
    public function addUserBookPermit(\xxxxBundle\Entity\BookPermit $book_book_permit)
    {
        $this->book_book_permit[] = $book_book_permit;

        return $this;
    }

    /**
     * Remove BookPermit
     *
     * @param \xxxxBundle\Entity\BookPermit $book_book_permit
     */
    public function removeUserBookPermit(\xxxxxBundle\Entity\BookPermit $book_book_permit)
    {
        $this->book_book_permit->removeElement($book_book_permit);
    }

    /**
     * Get BookPermit
     *
     * @return \Doctrine\Common\Collections\Collection
     */
    public function getUserBookPermit()
    {
        return $this->book_book_permit;
    }

在我的控制器中，我正在尝试返回一个object not found错误

public function displayAction(Request $request, Users $user, BookPermit $bookpermit)
    {

    $bookLists= $em->getRepository("xxxBundle:Books")->findBy(
        array(
            "usersfk" => $user,
            "usersfk" => $bookpermit
        )
    );


    }

在调用上述控制器时，它返回>>>xxxxBundle\Entity\BookPermit object not found。（找不到404）。
我的方法有什么问题

最佳答案

从操作中删除类型提示
而不是这个

public function displayAction(Request $request, Users $user, BookPermit $bookpermit)

更改为

public function displayAction(Request $request, $user, $bookpermit)
