我构建了一个非常简单的包，它没有依赖项，也不导入任何包。它唯一的内容是一个计算器服务接口和相应的实现类，其中只包含一个简单的add（inta，intb）方法

我为这个包创建了两个PaxExam测试容器，一个使用Karaf容器，另一个使用OSGI容器。Karaf容器测试可以正常工作，但OSGI测试容器不能

澄清一下。。。如果我将CalculatorService注入到OSGI测试容器中，并在JUnit测试用例中直接实例化CalculatorServiceImpl类，那么它就可以正常工作。因此，OSGI测试容器可以看到我的简单包中的类

一些问题：

  • 我的pom.xml文件中是否缺少一些东西来实现这一点
  • 我是否应该向OsgiTestClient.config（）方法添加更多捆绑包
  • 关于什么是保持非常简单的例子的其他想法
下面是我尝试将CalculatorService注入PaxExam OSGI测试容器时得到的堆栈跟踪

    }
}
最后一条注释，如果我注释掉注入CalculatorService的代码，代码运行良好（因为我正在手动实例化CalculatorImpl类）。因此，我的测试容器对计算器接口和实现具有编译时和运行时可见性。但这项服务的注入不起作用

最后提醒一下，当我构建PaxExam-Karaf测试容器时，计算器服务的注入是成功的，测试用例运行良好。错误出现在运行本文中描述的PaxExam OSGI容器时。

是的，那么默认情况下，blueprint堆栈/库没有安装在本机容器中（但它们在Karaf中）

您需要将此DEP添加到您的测试pom中：

这应该是个好办法

您能否提供有关如何在计算器示例中注册/发布服务的更多信息？我的意思是，您是使用声明性服务还是Blueprint，还是使用OSGi方法（ServiceTracker、registerServices…）呢。。。我已将blueprint.xml添加到原始帖子中。这很有效。。。谢谢你的时间，非常感谢。
