本文介绍了一个使用Struts框架的示例项目，包括JSP页面、Action类及配置文件的实现细节。通过点击链接，可以触发不同的Action方法，展示了Struts框架的基本用法。
建一个jsp页面代码如下：
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %>
<html:html locale="true">
<head>
<html:base />
<title>MyJsp.jsp</title>
</head>
<body>
<a href="modify.do?method=add">dfsd</a>
<a href="modify.do?method=update">dfsd</a>
</body>
</html:html>
建一个action代码如下:（注意：这里的action必须是继承DispatchAction）
package com.yourcompany.struts.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;
/**
* MyEclipse Struts
* Creation date: 01-05-2007
*
* XDoclet definition:
* @struts:action validate="true"
*/
public class ModifyAction extends DispatchAction {
// --------------------------------------------------------- Instance Variables
// --------------------------------------------------------- Methods
/**
* Method execute
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
*/
public ActionForward update(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
System.out.print("update");
// TODO Auto-generated method stub
return null;
}
public ActionForward add(ActionMapping mapping,ActionForm form,
HttpServletRequest request,HttpServletResponse response) {
System.out.print("add");
// TODO Auto-generated method stub
return null;
}
}
Struts-config.xml配置代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
<data-sources />
<form-beans />
<global-exceptions />
<global-forwards />
<action-mappings >
path="/modify"
parameter="method"
type="com.yourcompany.struts.action.ModifyAction" />
</action-mappings>
<message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>
注意：这里的parameter=method要和jsp页面连接问号后的变量一致
这样的点击add,update分别会在控制台上打出，add,update
