Question

我在文件夹[docx]中创建了一个新项目，并从文件夹实体中的现有数据库生成了实体。这是fetch.php代码：

<?php
// bootstrap.php
// replace with file to your own project bootstrap
require_once 'bootstrap.php';


$em->getConfiguration()->addEntityNamespace('', 'entities');

$UserRepo = $em->getRepository('User');


$data = $UserRepo->findAll();
echo '<pre>'; \Doctrine\Common\Util\Debug::dump($data);
exit;

以下是用户实体的代码：

<?php

use Doctrine\ORM\Mapping as ORM;

/**
 * User
 *
 * @ORM\Table(name="user", indexes={@ORM\Index(name="address_id", columns={"address_id"})})
 * @ORM\Entity
 */
class User
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="username", type="text", length=65535, nullable=false)
     */
    private $username;

    /**
     * @var \Address
     *
     * @ORM\ManyToOne(targetEntity="Address")
     * @ORM\JoinColumns({
     *   @ORM\JoinColumn(name="address_id", referencedColumnName="id")
     * })
     */
    private $address;



    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set username
     *
     * @param string $username
     *
     * @return User
     */
    public function setUsername($username)
    {
        $this->username = $username;

        return $this;
    }

    /**
     * Get username
     *
     * @return string
     */
    public function getUsername()
    {
        return $this->username;
    }

    /**
     * Set address
     *
     * @param \Address $address
     *
     * @return User
     */
    public function setAddress(\Address $address = null)
    {
        $this->address = $address;

        return $this;
    }

    /**
     * Get address
     *
     * @return \Address
     */
    public function getAddress()
    {
        return $this->address;
    }
}

当我尝试从此实体获取数据时，我收到错误：

第96行的

命名空间仅用于组织文件以避免冲突。如需帮助Link

您需要在代码中添加文件，如：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.google.firebase:firebase-core:11.8.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

有关更多信息，您需要检查doctrine autoload classes部分。

类'实体\用户'不存在？
