Question

作为一个Doctrine 2.1新手我试图开始使用Doctrine 2，但我仍然坚持看似基本的东西。但我仍然无法绕过它：

运行

$ doctrine orm:generate-entities Entities

Processing entity "MyUser"

Entity classes generated to "/home/lucvh/NetBeansProjects/doctrinetest/Entities"

生成我期望的MyUser.php文件（见下文）

然后我继续生成显然失败的模式，因为类加载器不工作，因为它似乎没有找到位于Entities目录下的MyUser类。我错过了什么......

$ doctrine orm:schema-tool:create
PHP Warning:  class_parents(): Class MyUser does not exist and could not be loaded in /usr/share/php/Doctrine/ORM/Mapping/ClassMetadataFactory.php on line 223
PHP Warning:  array_reverse() expects parameter 1 to be array, boolean given in /usr/share/php/Doctrine/ORM/Mapping/ClassMetadataFactory.php on line 223
PHP Warning:  Invalid argument supplied for foreach() in /usr/share/php/Doctrine/ORM/Mapping/ClassMetadataFactory.php on line 223

  Class MyUser does not exist

MyUser.php：

Answer 1

可能是因为您没有加载模块而导致此问题。

如果您使用ZF2，请确保在application.config.php中添加模块。如果您使用ZF3，则应将其包含在modules.config.php

中

我希望这有助于某人。

Answer 2

如果其他人遇到同样的问题，链接线程中的以下帖子可能会有所帮助：

Doctrine 2.0 ReflectionException when I try to do YAML Mapping

我遇到了同样的麻烦。诀窍是从中生成实体   将--generate-annotations选项设置为1的yaml文件。我已经   复制了我在下面使用的命令：

$ doctrine orm：generate-entities --generate-annotations = 1 Entities /

这样做是因为它与所有实体一起生成实体   映射信息。现在，如果您更改元数据驱动程序配置   你的bootstrap使用实体而不是yaml文件   架构创建应该有效。

Answer 3

也许，当我遇到同样的麻烦时，原因是没有命名空间。正如您在生成的Entity中看到的那样，没有命名空间，因此Doctrine无法找到它。

Doctrine 2配置问题，似乎找不到实体
