类org.apache.struts2.convention.DefaultClassFinder$InfoBuildingVisitor将接口org.objectweb.asm.ClassVisitor作为超类

Question

我将struts2版本从2.5.2改为2.5.10.1，并开始收到此错误。看起来新版本没有读取任何动作类。我需要用它来改变其他的库吗？我的应用程序正常启动，但我在控制台中看到了这个日志。

堆栈跟踪：

Answer 1

所以，我有struts2-约定插件，它造成了这个不兼容的问题。我删除了整个插件，因为在新版本的struts2中我不再需要它，应用程序开始正常工作，没有任何运行时错误。

Answer 2

这里的问题是jar不兼容。

Struts2约定插件(2.5.10)有编译依赖，它使用的是asm-5.1, asm-commons-5.1, asm-tree-5.1 jars。因此，如果您使用的是weblogic服务器，请添加

<wls:package-name>org.objectweb.asm.*</wls:package-name>

在你的weblogic.xml里。
