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 hell

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>
