1：创建动态Web工程
2：在web.xml里加入
<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：右键单击工程，选择MyEclipse-Project Facets-Install Apache Struts（2.x）Facet
4：新建一个Java类，在此命名为HelloWorld.java,并继承ActionSupport类
在里面重写execute()方法
package tutorial; import com.opensymphony.xwork2.ActionSupport; public class HelloWorld extends ActionSupport{ private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } public String execute() { name = "Hello, " + name + "!"; return SUCCESS; } }
5：配置struts.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <include file="struts-default.xml"/> <package name="tutorial" extends="struts-default"> <action name="HelloWorld" class="tutorial.HelloWorld"> <result>HelloWorld.jsp</result> </action> </package> </struts>
package里的name属性代表刚才所创建Java类的包名
6：修改index.jsp代码，在<body></body>之间插入一下代码
<h3>Say "Hello" to: </h3> <s:form action="HelloWorld"> Name: <s:textfield name="name" /> <s:submit /> </s:form>
7：新建HelloWorld.jsp,修改内容如下
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'HelloWorld.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <h3><s:property value="name" /></h3> </body> </html>
8：部署运行
