java - 添加Spring库时出现"Given parent is not an ancestor of this virtual file"错误

Question

我正在实现一些使用大量库(Spring、Log4j、Jackson 等)的 Web 应用程序。到目前为止，一切正常，但如果我尝试添加另一个 Spring 库(webmvc - 我正在实现需要 DispatcherServlet 类的 REST API)，则在 JBoss AS 上部署时会收到以下错误7.1.1:

这是我的 EAR 部署程序集

和我的网络模块组件。

我不知道为什么会出现这个错误，其他库不会造成任何麻烦。有什么建议吗？

编辑1:

我注意到另一件奇怪的事情。在 Eclipse 的“添加和删除”对话框中，可用资源部分有三个 Spring webmvc jar 条目。

这些条目来自哪里？难道是Eclipse的问题？

编辑2:

我已将所有 jar 直接移至 lib 文件夹中(而不是像 lib/spring/spring-webmvc-4.0.6.jar 这样的子文件夹)，并部署了我的应用成功。谁能解释为什么移动 jar 后该错误消失了？

Answer 1

从standalone/deployments 文件夹中删除以前的部署。清理服务器并重新部署 EAR。如果您使用的是 Java 6，您可以尝试将 java 版本更改为 Java 7。

Jboss AS 7.1.1 有很多这样的问题。如果可能，将服务器更改为 Jboss AS 7.2。这是 JBoss 7.1.2 中修复的问题之一。你可以看看这个link关于此错误及其修复的版本。
