请提供一些解决方案，提前感谢

Answer 1

使用Struts 2.3时，需要添加两个jar文件commons-lang3-3.2。jar和commons-lang-2.4。罐子

对于Maven，使用

<dependency>
  <groupId>org.apache.struts</groupId>
  <artifactId>struts2-core</artifactId>
  <version>2.3.24.1</version>
</dependency>

要下载完整的struts2罐去链接https://struts.apache.org/download.cgi#struts23241

下面是运行Struts 2.3 web应用程序所需的最小JAR集

Answer 2

请确保你的支柱。xml操作类映射是正确的

Answer 3

您缺少commons-lang3-3.1。jar（Struts 2.3需要，而不是更低版本）。

您可以（也应该）将其与commons-lang-2.6一起使用。jar，因为它们的包不同。

在Apache留档中查看所有Struts2依赖项。

下载两个commons lang版本的链接。
