No result defined for action action.LoginAction and result success 问题解决

搭建好SSH2框架，写一个简单的登陆功能，提交表单的时候遇到这个问题：

配置文件如下：

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  </filter-mapping>
    <filter-mapping>

  	<url-pattern>*.jsp</url-pattern>
  </filter-mapping></web-app>

spring配置文件：applicationContext.xml:

  	<url-pattern>*.jsp</url-pattern>
  </filter-mapping></web-app>

struts2.1配置文件struts.xml:

<?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>
	<constant name="struts.objectFactory" value="spring" />
	<package name="default" extends="struts-default" >
		<action name="userLogin" class="LoginAction">
			<result name="success">/success.jsp</result>
			<result name="input">/login.jsp</result>
		</action>
	</package>

</struts>

LoginAction.java:

	public String execute() {
		// TODO Auto-generated method stub
		
		return SUCCESS;
	}

登陆页面 login.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

</head>

<body>

		<s:password name="password" label="密码"></s:password>
		<s:submit type="button" value="登陆" />
	</s:form>
</body>
</html>

成功跳转页面 success.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"

</body>
</html>

这个是修改之后的正确代码，原来错误代码的struts.xml中的action的name是login，login.jsp中的action="login.action"，将这两个action改成“userLogin”之后就没有问题了，改成Login也是可以的。不知道是什么问题，希望了解的大神们指点一下。
