java - NoSuchMethodError org.apache.commons.collections.ExtendedProperties.getList(Ljava/lang/String;)Ljava/util/List in Struts 2

Question

我想将 Tiles 3 与 Strut 2 一起使用，所以我正在使用 struts2-tiles3-plugin。我在 web.xml 中定义了监听器，在 struts.xml 中定义了结果类型。当我部署 war 时，Tomcat 返回一个 java.lang.NoSuchMethodError。

这是我的web.xml:

Answer 1

您在 velocity 和 commons-collections 之间存在版本冲突。请注意，在您使用的 struts 版本中，它需要依赖于 commons-collections 3.2.1 的 velocity 1.6.4。另一方面，tiles 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在 IDE 中查看有效的 POM。
