最近我写了一个使用Pax考试在Karaf容器中运行的集成测试，这是我的代码：

但我发现它无法通过测试，因为测试包无法找到我的自定义服务类（IFramework框架）并报告：
java.lang.ClassNotFoundException: com.mercury.mof.foundation.framework.api.modular.IFramework not found by PAXEXAM-PROBE-45604164-c35f-448b-9627-af8adb7e16f7 [110]

我不知道问题出在哪里，实际上我在我的基础测试中注入了一些标准的osgi服务，它就像一个魅力，为什么当我使用自己的服务时它会导致麻烦？任何人都可以给我一些提示吗？非常感谢
答案 0 :(得分：1)
确保测试可以看到IFramework类的最佳方法是确保提供类的bundle安装在容器中。在@Configuration注释方法中使用mavenBundle是一个很好的方法。
您需要注意的事项： i）包含IFramework的包导出该类。 ii）如果您正在使用maven协调，请确保安装了人工制品（参见[1]）。 iii）确保满足捆绑导出IFramework的依赖关系。
所以与您的代码相关的评论： i）您不需要安装osgi core，compendium＆amp;企业（由karaf提供）。 ii）没有必要使用提供的东西来添加类和资源（我看到正在安装的类作为捆绑包和测试资源，无论如何都将可用。）
[1]：如果您的集成测试是与您在测试中使用的类相同的maven模块的一部分，则需要注意测试是在您的存储库中安装了artefact之前运行的，因此使用maven coords会导致问题。如果是这种情况，请考虑拆分测试，或不使用maven coords。
