1.jsp，ajax的循环调用，必须要递归，否则会出错。

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>
