struts2 从如下版本：
<struts2.version>2.5.10.1</struts2.version> <apache.commons.version>3.5</apache.commons.version>
升级到
<struts2.version>2.5.20</struts2.version>
之后报错如下：

解决方法为升级
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>${apache.commons.version}</version>
</dependency>
到更高的版本，如下：
<struts2.version>2.5.20</struts2.version> <apache.commons.version>3.8.1</apache.commons.version>
