1.jsp，ajax的循环调用，必须要递归，否则会出错。

<%@ 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+"/";

%>

2.action，就是简单的一条数据一条数据的保存，一定有get和set，注意Spring注入不能写get，会报错。

public String BatchScoreSave() throws Exception{

		score = new Score();

		score.setId(new ScoreId());

		score.getId().setClasss(classs);

		score.getId().setCourse(course);

		score.getId().setNumber(number);

		score.getId().setName(name);

		score.getId().setScore(scores);

		mgr.Scoresave(score);

		return SUCCESS;

	}

3.struts.xml

<package name="aaa" extends="json-default">

<action name="BatchScoreSave" class="ScoreAction" method="BatchScoreSave">

			<result name="success" type="json">

			<param name="root"></param>

			</result></action>
