我想在Struts2中使用Tiles3，所以我使用struts2-tiles3-plugin。我已在web.xml中定义了侦听器，在struts.xml中定义了结果类型。当我部署战争时，Tomcat返回java.lang.NoSuchMethodError。
这是我的web.xml：

答案 0 :(得分：1)
你在速度和公共集合之间存在版本冲突。请注意，在struts版本中使用它需要速度1.6.4，这取决于公共集合3.2.1。另一方面，tile插件仍然需要commons-collections 3.2。
您可以运行mvn dependency:tree来查看已解析的依赖项，或者在IDE中查看有效的POM。
