前台jsp页面，动态添加：
<br>
$(function() {<br>
$("#btnAddeducation").click(<br>
function() {<br>
var num = $("#educationhidNum").val(); <br>
num = parseInt(num);<br>
num++; <br>
$("#educationhidNum").val(num); <br>
$("#edcationaddtable").clone(true).attr("id", "edcationaddtable" + num).appendTo("#educationbackgrroundadd"); //clone <br>
$("#edcationaddtable" + num).each(function() {<br>
$(this).find("input[type='text']").val(""); </p>
<pre><code> $(this).find("input[name='educationBackgroundlist[0].startTime']").attr("id","educationStartTime"+ num).attr("name","educationBackgroundlist["+ num+"].startTime");
$(this).find("input[name='educationBackgroundlist[0].university']").attr("id","university"+ num).attr("name","educationBackgroundlist["+ num+"].university");

});
</script>
<script type="text/javascript">

if(a==0){
alert("该项不能删除！");
return;

document.getElementById("edcationaddtable"+a).remove();

后台Action：
private List educationBackgroundlist = new ArrayList();
public Resume backresume() throws Exception {
List educationBackgroundlist1 = this.educationBackgroundlist();
Resume resume = new Resume();
resume.setResumeID(resumeID);
resume.setApartment(apartment);
resume.setAppliedPosition(appliedPosition);
resume.setDestination(destination);
resume.setEducationBackground(educationBackgroundlist1);
resume.setEmail(email);
resume.setEvaluation(evaluation);
resume.setExpectation(expectation);
resume.setFamilySituation(familySituation);
resume.setLanguageProficiency(languageProficiency);
resume.setMotivation(motivation);
resume.setNationality(nationality);
resume.setOperatingTime(operatingTime);
resume.setOperator(operator);
resume.setOther(other);
resume.setPersonalAge(personalAge);
resume.setPersonalName(personalName);
resume.setPersonalSex(personalSex);
resume.setPhoneNum(phoneNum);
resume.setResumeState(resumeState);
resume.setSourceCompany(sourceCompany);
resume.setWorkSeniority(workSeniority);
return resume;
}
public String addresume() throws Exception {
Resume resume = this.backresume();
resumeService.save(resume);
Pageres pageres = this.pageser();
list = resumeService.queryresumelist(resume,pageres,workSeniority1,workSeniority2,pageNo,pageSize);
return SUCCESS;
}
Resume简历为主表，EducationBackground为简历从表教育背景表，两个表都有主外键关系，
@OneToMany(fetch = FetchType.EAGER,targetEntity=EducationBackground.class,cascade={CascadeType.ALL},orphanRemoval=true)
// @Cascade(value={org.hibernate.annotations.CascadeType.ALL})
// @NotFound(action = NotFoundAction.IGNORE)
@JoinColumn(name="resume_id")
public List getEducationBackground() {
return educationBackground;
}
public void setEducationBackground(List educationBackground) {
this.educationBackground = educationBackground;
}
@ManyToOne(targetEntity=Resume.class,fetch = FetchType.EAGER)
@JoinColumn(name="resume_id",referencedColumnName="resumeID", insertable=true, updatable=true)
public Resume getResume() {
return resume;
}
public void setResume(Resume resume) {
this.resume = resume;
}
数据访问层的sava()方法;
@Override
public void save(Resume resume) {
Session session = sessionFactory.openSession();
//Session session = sessionFactory.getCurrentSession();
Transaction tx = session.beginTransaction();
//session.persist(resume);
//session.save(resume);
session.persist(resume);
tx.commit();
session.close();
}
当我在action中手动添加教育背景的数据时，数据为多条，可以插入数据库，但是我换成jsp动态添加时 就报上面的错误，是怎么回事啊 ？？ 求大神帮帮忙，万分感谢！
