Doctrine 2从findBy查询结果中获得0条结果

请注意以下代码。这是函数内部的一个片段。Doctrine 2从findBy查询结果中获得0条结果

global $entityManager; 
$username = $request->getParam('username'); 
$password = $request->getParam('password');

我再次检查上面，并正确得到它。

$results = $entityManager->getRepository('Entity\User')->findBy(array('username' => $username, 'password' => $password));

这将返回0结果时，它应该返回2，我在数据库中。我验证了我通过检查我的配置连接到正确的数据库，如果没有正确设置，它会抛出错误。

我的实体管理器是在我的推进过程中创建的。这是它的样子。

bootstrap.php中

<?php 

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

require_once('config/config.php'); 

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

// The database connection configuration 
$dbParams = array(
    'driver' => 'pdo_mysql', 
    'host'  => $config['host'], 
    'user'  => $config['dbusername'], 
    'password' => $config['dbpassword'], 
    'dbname' => $config['dbname'], 
); 

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

function GetEntityManager(){ 
    global $entityManager; 
    return $entityManager; 
} 

?>

我的用户实体如下。

user.php的

我在做什么错？
