使用这种方式也需要通过请求参来来指定要执行的动作。请求参数名的格式为
　　action!method.action
　　注：由于Struts2只需要参数名，因此，参数值是什么都可以。

下面我就给出一个实例程序来演示如何处理有多个submit的form：

主页面more_submit.jsp

复制代码代码如下:

<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head>   
<title>My JSP 'hello.jsp' starting page</title>
</head>
<body>
    <s:form action="submit.action">
        <s:textfield name="msg" label="输入内容" />
        <s:submit name="save" value="保存" align="left" method="save" />
        <s:submit name="print" value="打印" align="left" method="print" />
    </s:form>
</body>
</html>

MoreSubmitAction.java

复制代码代码如下:

package action;

import javax.servlet.http.*;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.interceptor.*;

public class MoreSubmitAction extends ActionSupport implements
        ServletRequestAware {
    private String msg;
    private javax.servlet.http.HttpServletRequest request;

    // 获得HttpServletRequest对象
    public void setServletRequest(HttpServletRequest request) {
        this.request = request;
    }

    // 处理save submit按钮的动作
    public String save() throws Exception {
        request.setAttribute("result", "成功保存[" + msg + "]");
        return "save";
    }

    // 处理print submit按钮的动作
    public String print() throws Exception {
        request.setAttribute("result", "成功打印[" + msg + "]");
        return "print";
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }
}

structs.xml

复制代码代码如下:

<?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>

    <package name="demo" extends="struts-default">
        <action name="submit" class="action.MoreSubmitAction">
            <result name="save">
                /result.jsp
            </result>
            <result name="print">
                /result.jsp
            </result>
        </action>
    </package>

 
</struts>

result.jsp

复制代码代码如下:

<%@ page language="java" contentType="text/html; charset=GBK"
pageEncoding="GBK"%>
<!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>提交结果</title>
</head>
<body>
<h1>${result }</h1>
</body>
</html>
