理论EntityManager误差

Question

我有一个文件: config.php，其中包含以下代码：

​

require 'vendor/autoload.php';

//doctrine
use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

$paths = array(
	__DIR__ . "/entidades"
);

$isDevMode = false;
//configuracion de coneccion
$dbParams = array(
	'driver' => 'pdo_mysql',
	'host' => '127.0.0.1',
	'user' => 'root',
	'password' => '',
	'dbname' => 'ClinicaDental'
	 
);

$configDoctrine = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode, null, null, false);
$entityManager = EntityManager::create($dbParams, $configDoctrine);

​

而这个文件nuevo_archivo.php

$resultados = $entityManager->getRepository('\entidades\usuarios')->findAll();
        echo "<pre>";
        print_r($resultados);
        echo "</pre>";

运行nuevo archivo.php文件时收到的错误如下：

Fatal error: Uncaught exception 'Doctrine\Common\Persistence\Mapping\MappingException' with message 'Class '\entidades\usuarios' does not exist' in /Applications/XAMPP/xamppfiles/htdocs/ClinicaDental/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php:96 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/ClinicaDental/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/RuntimeReflectionService.php(41): Doctrine\Common\Persistence\Mapping\MappingException::nonExistingClass('\\entidades\\usua...') #1 /Applications/XAMPP/xamppfiles/htdocs/ClinicaDental/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php(281): Doctrine\Common\Persistence\Mapping\RuntimeReflectionService->getParentClasses('\\entidades\\usua...') #2 /Applications/XAMPP/xamppfiles/htdocs/ClinicaDental/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php(311): Doctrine\Common\Persistence\Mapping\AbstractClassMetadataFactory->getPare in /Applications/XAMPP/xamppfiles/htdocs/ClinicaDental/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php on line 96

我的文件夹是保存我的实体的地方，在我看来，实体是另一个文件夹中的实体，从那里我告诉他。

你试过不带\吗？

您可以尝试以下代码：

var_dump(get_declared_classes());

并检查是否可以看到您的usuarios类。

您还可以尝试使用a：

use entidates\usuarios;

$entityManager->getRepository('usuarios')->findAll();
