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

MoreSubmitAction.java

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

/result.jsp

/result.jsp

result.jsp

pageEncoding="GBK"%>

${result }
