Hibernate 3.5 或 3.6 不支持 @Any 注释？

我目前正在进行系统迁移（从带有JPA1的hibernate 3.2.2.GA到带有JPA2的hibernate 3.6）。迁移本身非常简单，没有重大更新要做（事实上，我认为没有我面临的

问题是 hibernate 在运行时抛出异常，抱怨 @Any 注释。

Caused by: java.lang.UnsupportedOperationException: any not supported yet
    at org.hibernate.ejb.metamodel.AttributeFactory.determineAttributeMetadata(AttributeFactory.java:452)
    at org.hibernate.ejb.metamodel.AttributeFactory.buildAttribute(AttributeFactory.java:93)
    at org.hibernate.ejb.metamodel.MetadataContext.wrapUp(MetadataContext.java:183)
    at org.hibernate.ejb.metamodel.MetamodelImpl.buildMetamodel(MetamodelImpl.java:66)
    at org.hibernate.ejb.EntityManagerFactoryImpl.<init>(EntityManagerFactoryImpl.java:84)
    at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:902)
    at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:74)
    at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:225)

因此，这意味着 hibernate 不再支持 @Any 或 @ManyToAny。很奇怪，因为文档（从 3.3 到 3.6）提到了如何使用 @Any 注释，而且据我所知，没有 hibernate 版本贬低此注释。

我检查了 hibernate 3.5 源代码，并且 @Any 注释检查也在那里，所以它也存在。抛出同样的异常，

你们有解决这个问题的方法吗

？

I'm currently working on a system migration (from hibernate 3.2.2.GA with JPA1 to hibernate 3.6 with JPA2. The migration itself is very simple, there are no major updates to do (in fact, I don't think there is any at all).

The problem I'm facing is that hibernate throws an exception at runtime, complaining about the @Any annotations. The stacktrace is the following:

Caused by: java.lang.UnsupportedOperationException: any not supported yet
    at org.hibernate.ejb.metamodel.AttributeFactory.determineAttributeMetadata(AttributeFactory.java:452)
    at org.hibernate.ejb.metamodel.AttributeFactory.buildAttribute(AttributeFactory.java:93)
    at org.hibernate.ejb.metamodel.MetadataContext.wrapUp(MetadataContext.java:183)
    at org.hibernate.ejb.metamodel.MetamodelImpl.buildMetamodel(MetamodelImpl.java:66)
    at org.hibernate.ejb.EntityManagerFactoryImpl.<init>(EntityManagerFactoryImpl.java:84)
    at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:902)
    at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:74)
    at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:225)

So it means that @Any or @ManyToAny are no longer supported by hibernate. This is weird because the documentation (from 3.3 to 3.6) mentions how to use the @Any annotation and AFAIK there is no hibernate version that depreciates this annotation.

I checked hibernate 3.5 source code and the @Any annotation checking is there also, so it also throws the same exception.

Do you guys have any workaround for this issue?

thanks a lot!

您能否尝试将其添加到您的 Hibernate 属性中：

hibernate.ejb.metamodel.generation=disabled

这应该禁用元模型生成，避免您看到的异常。
（如评论中指出的那样，将属性值编辑为“禁用”）

Would you please try to add this to your Hibernate properties:

hibernate.ejb.metamodel.generation=disabled

This should disable the metamodel generation, avoiding the exception you are seeing.
(Edited property value to say 'disabled' as pointed out in comments)
