加载关联对象会导致错误

Question

我有两个对象，分别是Osoba和Adresa。它们都正确地映射了条令注释Osoba和Adresa是一对一的关联。

我可以使用实体管理器分别加载Osoba和Adresa。只要Osoba没有填充属性Adresa，它就可以正常工作。但当我用属性Adresa保存Osoba并试图从数据库检索对象时，抛出了一个错误。

这就是我试图获取对象Osoba的方式。数据库中id为13的Osoba包含指向Adresa表的id。

$osoba = $entityManager->find("Osoba", 13);

抛出的错误是

Fatal error: require(): Failed opening required 'C:\Users\xxx\AppData\Local\Temp\__CG__Adresa.php' (include_path='C:\xampp\php\PEAR') in C:\xampp\htdocs\vendor\doctrine\common\lib\Doctrine\Common\Proxy\AbstractProxyFactory.php on line 206

这是我的Osoba和Adresa实体。

好吧，我找到问题所在了。

条令通过条令自身生成的代理对象连接到数据库。在为条令创建配置时，有两个选项—将dev mode设置为true或false。当dev mode设置为false时，它不会每次生成代理，只生成一次。因此，您需要至少将dev mode设置为true一次，或者自己生成类，这在下面的回答中进行了解释：https://stackoverflow.com/a/20231349/1869111
