1.导入struts2类库
2.在web.xml 文件中配置FilterDispatcher
<span style="white-space:pre"> </span><filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
<filter-mapping>
3.编写action类
可以是普通的有execute()函数的类、可以实现action接口、可以继承ActionSupport类
4.编写结果页面
使用struts标签库时,
<%@ taglib prefix=“s” uri="/struts-tags" %>
5.在struts.xml文件中配置action
<!DOCTYPE struts PUBLIC

<struts>
<span style="white-space:pre"> </span><package name="HelloWorld" extends="struts-default">
