ZF2、Oracle、SlmQueueDoctrine、ClearObjectManagerStrategy不起作用

Question

我有一个ZF2项目，配置如下。它使用的是条令ORM和SlmQueue。由于SlmQueue不支持我们的命名约定和oracle数据库，因此我们定制了SlmQueueDoctrine。

我怀疑我的作业没有使用ClearObjectManagerStrategy，并且在执行单个作业之前没有清除ObjectManager。

它不反映队列启动后对数据库的修改。但如果我终止队列守护进程并重新启动，它会选择新的值。

如何在执行单个作业之前实现ClearObjectManagerStrategy并清除ObjectManager？

我试过很多次都没有成功。

Answer 1

如果你的意思是它没有完全清除，那么显然这不是一个bug，而是预期的行为。

您可以查看文档第7.5章。了解调用clear方法的行为：

当调用EntityManager#clear（）时，当前由EntityManager实例管理的所有实体都将分离。

在您的评论中，您说过"它不会刷新对象管理器和当前事务"。这不是一个你可以期望调用clear的操作。根据文件，分离会导致以下操作：

应用于实体X的分离操作的语义如下：

• 如果X是托管实体，则分离操作会使其分离。如果从X到这些其他实体的关系是用cascade=detach或cascade=ALL映射的，则分离操作级联到X引用的实体（请参见"传递持久性"）。以前引用X的实体将继续引用X
• 如果X是新实体或已分离实体，则分离操作会忽略它
• 如果X是已删除的实体，则分离操作级联到X引用的实体，如果从X到这些其他实体的关系映射为cascade=detach或cascade=ALL（请参见"传递持久性"）。以前引用X的实体将继续引用X
