Question

我有一个超级实体类，在我的EJB项目中定义了继承策略TABLE_PER_CLASS。我尝试使用EJB3Unit进行单元测试，但只是意识到EJB3Unit尚不支持继承策略TABLE_PER_CLASS。还有其他支持它的测试库吗？我试着谷歌但没有出现......

Answer 1

也许看看OpenEJB。这是一个example that uses JPA。我不知道它是否涵盖了您的具体情况，但应该足够接近。

请注意，download page上有一个示例zip文件，其中包含大约二十多个这样的示例。所有这些都是单元测试，它们涵盖了EJB API的全部范围，包括MDB，Web服务，事务，安全性，当然还有基本的东西，如JPA，DataSources等。

Answer 2

现在呢。你应该检查：

Table per Class inheritance in EJB3 Entities on docs.jboss.org

代码示例：

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public class Pet implements java.io.Serializable
{

...

}

我希望我能帮忙。

任何支持继承策略TABLE_PER_CLASS的EJB单元测试库？
