tomcat - 在tomcat中运行应用程序时如何解决链接错误？

Question

因为我正在使用 MaintainJ 来跟踪我们的应用程序以自动创建 UML 图。我将 MaintainJ.war 和我们的 application.war 部署到 Web 应用程序中并开始使用 MaibntainJ 应用程序，在某些时候我必须使用 set JAVA_OPTS 在 tomcat 中为 MaintainJ 设置 JVM 属性，我这样做了但是当我启动 tomcat 并坚持使用时出现以下异常在 tomact 中设置 jvm 属性。

有人可以帮我解决这个问题吗？

Answer 1

当您将 aspectjrt.jar 或 aspectjweaver.jar 部署在与 MaintainJ 相同的容器中的其他应用程序中时，会发生此错误。 MaintainJ 代理已经在类路径中较高位置的那些 jar 文件中添加了类。

当您使用 MaintainJ 部署应用程序时，请从其他应用程序中删除 aspectjrt.jar 和 aspectjweaver.jar 文件。

那就行了!
