symfony - 未定义索引 : inverseJoinColumns while trying to define ManyToMany relationship between two entities

Question

我有两个实体:用户和公司，它们之间的关系是 n:m。在我的 User.php实体我有这个代码:

/**
 * @ORM\ManyToMany(targetEntity="PL\CompanyBundle\Entity\Company", mappedBy="users", cascade={"all"})
 */
protected $companies;

public function __construct() {
    $this->companies = new \Doctrine\Common\Collections\ArrayCollection();
}

public function setCompanies(\PL\CompanyBundle\Entity\Company $companies) {
    $this->companies = $companies;
}

public function getCompanies() {
    return $this->companies;
}

而在我的 Company.php实体我有这个其他代码:

/**
 * @ORM\ManyToMany(targetEntity="Application\Sonata\UserBundle\Entity\User", mappedBy="companies")
 */
protected $users;

public function __construct() {
    $this->users = new \Doctrine\Common\Collections\ArrayCollection();
}

但我收到了这个错误:

ContextErrorException: Notice: Undefined index: inverseJoinColumns in /var/www/html/apps/portal_de_logistica/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/BasicEntityPersister.php line 1041

映射有什么问题？

编辑重构代码

按照@ahmed-siouani 的指示，我进行了以下更改:
User.php

/**
 * @ORM\ManyToMany(targetEntity="PL\CompanyBundle\Entity\Company", inversedBy="users")
 * @ORM\JoinTable(name="fos_user_user_has_company",
 *      JoinColumns={@ORM\JoinColumn(name="fos_user_user_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="company_id", referencedColumnName="id")}
 * )
 */
protected $companies;

哪里 fos_user_user_has_company是为 n:m 添加的表关系。
Company.php

/**
 * @ORM\ManyToMany(targetEntity="Application\Sonata\UserBundle\Entity\User", mappedBy="companies")
 */
protected $users;

现在错误是:

AnnotationException: [Creation Error] The annotation @ORM\JoinTable declared on property Application\Sonata\UserBundle\Entity\User::$companies does not have a property named "JoinColumns". Available properties: name, schema, joinColumns, inverseJoinColumns

任何？

我的错是 ManyToMany 的两侧都用mappedBy 定义，但只有一侧应该使用mappedBy，另一侧应该使用inversedBy(这通常在控制集合的主实体中定义)。
