package myFirstStrust2WebProject.Model;
public class myStruts2Model {
private String message;
public myStruts2Model( ) {
super();
this.message = "this my first Struts2WebProject";
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
package myFirstStrust2WebProject.Action;
import myFirstStrust2WebProject.Model.myStruts2Model;
import com.opensymphony.xwork2.ActionSupport;
public class myStruts2Action extends ActionSupport {
/**

*/
private static final long serialVersionUID = 1L;
private myStruts2Model myModel;
public String execute() throws Exception {
myModel = new myStruts2Model() ;
return "success";
}
public myStruts2Model getMyModel() {
return myModel;
}
public void setMyModel(myStruts2Model myModel) {
this.myModel = myModel;
}
}
添加myFirstStruts2Web.jsp，内容如下：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>myFirstWebStructs2Web!</title>
</head>
<body>
<h2><s:property value="myModel.message" /></h2>
</body>
</html>
<pre name="code" class="html"><?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.devMode" value="true" /> <package name="basicstruts2" extends="struts-default"> <action name="myFirstStruts2" class="myFirstStrust2WebProject.Action.myStruts2Action" method="execute"> <result name="success">/myFirstStruts2Web.jsp</result> </action> </package> </struts>
<constant name="struts.devMode" value="true" />
struts.devMode也就是struts的开发模式，默认值为false，改为true就是以后一旦就改这个文件中的配置就不用去重启tomcat<action name="<span style="color: rgb(57, 51, 255); font-family: Monaco; font-size: 11px;">myFirstStruts2</span>">struct.xml -> 找到对应的class -> 实例化对象 -> 执行对应的execute（）方法
ActionSupport源
public String execute() throws Exception {
return SUCCESS;
}
最常用的是从ActionSupport继承，好处在于可以直接使用Struts2封装好的方法。<pre name="code" class="html"><?xml version="1.0" encoding="UTF-8"?>
