1.jsp,ajax的循环调用,必须要递归,否则会出错。

 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>
