- asm-commons-x.x.jar：官方说要加，但我不加也行
- asm-tree-x.x.jar：官方说要加，但我不加也行
- Struts2-core-2.x.x.jar：Struts2框架的核心类库；
- xwork-2.x.x.jar ：xwork类库，Struts2是在其之上构建的；
- ognl-2.6.x.jar：对象图导航语言（Object Graph Navigation Language），Struts2框架通过其读写对象属性；
- freemarker-2.2.x.jar：Struts2的UI标签的模板使用freemarker编写；
- commons-fileupload-1.2.1.jar：文件上传组件， 2.1.6版本后必须加入文件；
- javassist-3.11.0.GA.jar：Javassist是一个开源的分析、编辑和创建Java字节码的类库；
- commons-io-2.0.1.jar：IO输入输出流组件，主要完成文件的读写功能；
- commons-lang3-3.1.jar：commons-lang是一个很有用的开源包，它弥补了Java API在提供的基本处理方法上的不足；
- commons-lang3-X.X.X.jar： as from version 2.3.3 Struts 2 bases on Commons Lang 3, but there are still external dependencies that base on Commons Lang.
- commons-logging-1.1.x.jar：ASF出品的日志包，Struts2框架使用这个日志包来支持Log4J和JDK1.4+的日志记录（如果不想显示日志的话，不需要导入）。
