java - 处理应用程序的注释时失败。错误是在合并 Web 片段时发现冲突

Question

我有一个应用程序可以在之前的版本上正常工作WebLogic-12.2.1.2 但是一旦我升级到 WebLogic 12.2.1.2 它就会抛出以下异常。

<Error> <HTTP> <BEA-101371> <There was a failure when processing annotations for application. Ensure that the annotations are valid. The error is Conflict found while merging web fragment, weblogic.j2ee.descriptor.WebFragmentBeanImpl@7740fbd5() : Version>

我实际上在我的应用程序中包含了一个项目，它使用 servlet-api 3.0(以使用 Async servlet 的某些功能)并且我正在使用 servlet-api 2.4 在我的应用程序中。此外，该应用程序没有任何网络片段概念。会因此有什么冲突吗？任何帮助将不胜感激。

Answer 1

从 Weblogic 12c 开始，会扫描 jars 以查看是否存在 web 片段，然后与应用程序的 web.xml 合并。如果您的应用程序 web.xml 或其他 jars web-fragment.xml 具有不同的 DTD 版本，则会出现此问题。需要使所有 DTD 版本合格。
