Struts2学习笔记——基本配置
首先下载Struts2的jar库。
地址：http://struts.apache.org/download.cgi#struts232-SNAPSHOT
将需要的jar库拷贝到WEB-INF下的lib中。基本的9个包是：
commons-fileupload-xxx.jar
commons-io-xxx.jar
commons-lang-xxx.jar
commons-logging-xxx.jar
freemarker-xxx.jar
javasist-xxx.jar
ognl-xxx.jar
struts2-core-xxx.jar
xwork-core-xxx.jar
在web.xml中添加filter支持struts2
<filter> <filter-name>struts</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> <init-param> <param-name>struts.action.extension</param-name> <param-value>action</param-value> </init-param></filter><filter-mapping> <filter-name>struts</filter-name> <url-pattern>/*</url-pattern></filter-mapping>
