是否有支持继承策略 TABLE_PER_CLASS 的 EJB 单元测试库？

Question

我有一个超级实体类，其继承策略 TABLE_PER_CLASS 在我的 EJB 项目中定义。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？我尝试用谷歌搜索，但没有任何结果......

Answer 1

也许看看 OpenEJB。这是一个使用 JPA 的示例。我不知道它是否涵盖了您的确切场景，但应该足够接近。

请注意，下载页面上有一个示例 zip 文件，其中还有大约两打类似的示例。所有这些都是单元测试，几乎涵盖了 EJB API 的全部范围，包括 MDB、Web 服务、事务、安全性，当然还有 JPA、数据源等基本内容。

Answer 2

现在已经可以了。您应该检查：

文档上的 EJB3 实体中的每个类继承表.jboss.org

代码示例：

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

...

}   

希望对您有所帮助。
