我在嵌入式模式下使用openEjb来测试无状态 session Bean,该 session Bean具有注入(inject)的EntityManager。但是,当我运行测试时,它失败了,因为它无法初始化应用程序。当我看到控制台时,我还可以看到与无法找到persistence.xml有关的错误

注意:我尝试将WebContent以及META-INF放在类路径中,但这都无济于事。

更新:

使用openejb + eclipse时,资源查找有些奇怪。

  • 我将WebContent添加到源文件夹。我停止收到persistence.xml错误,但是现在我收到一条错误消息,表明openejb找不到任何托管资源
  • 我将WebContent添加到源文件夹,但是具有不同的输出文件夹(对源文件夹使用允许输出文件夹),并且开始再次出现persistence.xml错误
  • 我将META-INF复制到'test',这是所有测试的源文件夹,并且一切运行正常
  • 关于第1点和第2点,问题似乎是WEB-INF也作为WebContent的一部分被包含的事实。如果我不包括WEB-INF,那么openejb可以再次在测试中找到persistence.xml,并且测试运行良好

  • 老实说,我对正在发生的事情一无所知。

    我在下面粘贴所有相关的错误和代码。

            assertNotNull(oSlideService);
            this.slideService = (SlideService)oSlideService;
        }
    
        //not showing test methods for brevity, since the code fails in setUp itself
    }
    

    最佳答案

    我收到了相同的异常,问题是OpenEJB的类路径上有两个persistence.xml

    当我删除其中一个时,问题就解决了。

    在部分OpenEJB上,异常消息没有帮助,但是如果您调试org.apache.openejb.config.AppmodulehasFailures()hasErrors()方法,则可以在EjbModule.getValidation()调用中看到更多有用的信息! (版本4.0.0)。
