手工创建 Strut2 应用
Tomcat的webapps文件夹下面的文件结构如下图
struts2qs
|----WEB-INF
| |----classes(struts.xml , LoginAction.class)
| |----lib(struts2-core.jar, xwork-core.jar, ognl.jar, freemarker.jar, commons-logging.jar, commons-io.jar, comons-fileupload.jar, commons-long.jar, javassis.GA.jar )
| |----web.xml
|----login.jsp
|---welcome.jsp
|---error.jsp
其中javassis.GA.jar 在structs/lib里面没有，在struts app里面有
其中， struts.xml
<?xml version="1.0" encoding="GBK"?>
<!DOCTYPE struts PUBLIC

"http://struts.apache.org/dtds/struts-2.0.dtd">

<package name="lee" extends="struts-default">
<action name="Login" class="lee.LoginAction">
<result name="error">/error.jsp</result>
<result name="success">/welcome.jsp</result>
</action>
</package>
</struts>
web.xml
<?xml version="1.0" encoding="GBK"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

<!-- 定义Struts2的FilterDispathcer的Filter -->

其中，<filter-class>中，在struts2.1之前是org.apache.struts2.dispatcher.FilterDispatcher。structs2.1之后是org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilterlogin.jsp
