使用 Spring 的 Rest Web 服务未在 weblogic 12.2.1 中调用
Rest Web Services using Spring are not invoked in weblogic 12.2.1
我们正在考虑将我们的应用程序升级到 Weblogic 12.2.1。服务器正常启动。但是我们无法调用任何网络服务。它们是使用 Spring 编写的。我们还使用 JDK 8.
日志中出现的错误消息是:
org.springframework.web.servlet.PageNotFound No mapping found for HTTP request with URI [/test/components] in DispatcherServlet with name 'dispatcher' [noHandlerFound:1120 {}]
仅当我们使用安装程序安装应用程序时才会出现此问题。 当我们在开发环境中部署应用程序时,问题没有出现。我们能够成功调用服务。
我们比较了安装程序和开发中的类路径,它们是一样的。

请给我们任何帮助解决问题的建议。
我们已经向 Oracle 提出了一个案例。与此同时,我们找到了解决上述问题的方法。
如果其余 类 在 WEB-INF/classes 或 WEB-INF/lib 下可用,这似乎可行。以前,我们从 "higher" 类加载器、ear/lib(通过 application.xml 设置为 lib)加载 类,然后我们看到了问题。
当然,在 WLS 12.1.3 中,我们从未遇到过任何问题。包含 REST 类 的 .jar 仅在 ear/lib 中,而不在 WAR.
