我遇到了一个似乎更频繁地发生在人们身上的错误，但是来源因各种原因而异。在测试人员可以测试它的服务器上部署项目之后，在某些地方执行应用程序中的任务时出现此错误＆lt; NoClassDefFoundError＆gt;弹出。
现在iv在互联网上阅读了很多，有些人发生这种情况，因为有些人错过了匹配，因为他们在他们的环境中没有某些权限，有些人遗漏了一些依赖关系。但对我来说似乎确实如此。
或者我只是感到沮丧，我不确定是不是老实说。因此，希望有人看到堆栈中的某些东西可能已经跳过了我的视线或某些东西，我转向Stack Overflow以期获得救赎....
现在我知道这个班级位于＆lt; jaxb-api＆gt;罐。在项目pom中，它设置为使用版本2.2.2。我甚至使用在线反编译器反编译罐子来检查罐子。该课程存在。在我当地的环境中它工作正常。只有在服务器上部署后才会发生这种情况。
提前谢谢!!!对不起，如果我的问题不清楚，我会编辑它，以便更清楚，如果可能的话。
堆栈跟踪如下：

答案 0 :(得分：1)
如果您使用的是Java 6或更新版本，了解JAXB附带JDK非常重要。
通常，您永远不会在pom.xml文件中包含JAXB API jar或JAXB实现，因为您已经可以通过JDK访问这些内容。这样做会导致特殊的类加载问题，例如您描述的问题。
如果 需要 使用JAXB 2.2，则必须使用Java 8构建和执行代码。
Java 6和7附带JAXB 2.1。
现在，如果您的代码在完整堆栈Java EE 6（或更新版本）服务器（如WildFly，GlassFish，TomEE等）中运行，则上述情况并非如此。
这些规范旨在提供正确集成的JAXB 2.2实现。
在这种情况下，您可以针对JAXB 2.2 API构建。您仍应排除任何实施。
如果你想使用Tomcat和JAXB 2.2这样的东西，那么你需要使用Class Loader HOW-TO中描述的endorsed目录将JAXB 2.2实现安装到Tomcat中，该目录建立在{{3}上}}。 Jetty也需要类似的解决方案。
