我想使用这段代码，它在 flush() 上中断，没有任何异常消息：

1. at PDOStatement ->execute (null) 
in ../vendor/doctrine-dbal/lib/Doctrine/DBAL/Statement.php at line 131    
2. at Statement ->execute () 
in ../vendor/doctrine/lib/Doctrine/ORM/Persisters/BasicEntityPersister.php at line 237    
3. at BasicEntityPersister ->executeInserts () 
in ../vendor/doctrine/lib/Doctrine/ORM/UnitOfWork.php at line 726    
4. at UnitOfWork ->executeInserts (object(ClassMetadata)) 
in ../vendor/doctrine/lib/Doctrine/ORM/UnitOfWork.php at line 292    
5. at UnitOfWork ->commit () 
in ../vendor/doctrine/lib/Doctrine/ORM/EntityManager.php at line 334    
6. at EntityManager ->flush () 
in ../src/Tools/TFIBundle/Model/CSVImport.php at line 136    
7. at CSVImport ->addCategory ('fundusz obligacji') 
in ../src/Tools/TFIBundle/Model/CSVImport.php at line 114

addCategory() 方法看起来：

public function addCategory( $categoryName )
{
    $category = new Category();
    $category->setName( $categoryName );

    $this->em->persist( $category );
    $this->em->flush();
    $this->counter['category']++;

    return $category;
}

知道有什么问题吗？或者如何在 symfony2 中获取 PDOException 消息？

就在几秒钟前，我遇到了同样的问题。当我进入生产模式并关闭会话时，它得到了修复。当您在会话仍然存在的情况下进行大量更改替换整个文件夹等操作时，开发模式似乎存在会话问题。

尝试清除您的会话，它可能会起作用。
