我正在Weblogic 12c上部署EAR包，并获得ClassNotFoundException。但是，似乎该项目没有任何对相关缺失类的引用（我搜索了类名称为零结果）。我知道当尝试通过反射实例化缺少类时抛出此异常。我怀疑某些图书馆可能依赖于这门课程。
如何找出导致类实例化的配置或用户代码？服务器日志没有提供足够的详细信息，但这里是

您的Weblogic无法加载管理控制台。也许在qustion中类的应用程序的更频繁部署失败了。请尝试以下方法：
关闭该域下的所有群集
删除所有服务器上的 tmp 和缓存文件夹
在待处理的目录下删除 config.xml 文件
删除/ config和/ domain文件夹下所有服务器上的 * .lok 文件
重新启动管理
重新启动所有受管服务器
现在部署 war / ear 文件，它应该可以正常工作......

您可以在IDE中使用异常断点来捕获ClassNotFoundException。添加此类断点时，一旦发生异常，执行将暂停。然后，您可以遍历可在IDE中找到的堆栈，并通过选择堆栈行，查看每个步骤中的数据，以找出代码尝试实例化该类型对象的位置。

您的应用程序无法加载＆＃39; fi.foo.bar.service.FoobarWebServiceImpl＆＃39;，它位于WebAppModule的WebAppServletContext中。在web.xml或weblogic.xml中仔细检查＆＃39; fi.foo.bar.service.FoobarWebServiceImpl＆＃39;的拼写错误的类名。
