Question

我有两个对象，分别名为Osoba和Adresa。他们两个都正确地映射了学说注释。 Osoba和Adresa一对一关联。

我可以通过实体管理器分别加载Osoba和Adresa。只要Osoba没有填充Adresa的属性，它就可以正常工作。但是，当我使用属性Adresa保存Osoba并尝试从数据库中检索对象时，就会引发错误。

这就是我尝试获取对象Osoba的方式。数据库中ID为13的Osoba包含一个指向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。

好的，我发现了问题所在。

Doctrine通过由代理本身生成的代理对象连接到数据库。在为配置文件创建配置时，有两个选项-将dev模式设置为true或false。当开发人员模式设置为false时，它不会每次都生成代理，而是仅生成一次代理。因此，您需要至少将dev模式设置为true一次，或者自己生成类，对此答案进行了解释：https://stackoverflow.com/a/20231349/1869111
