我正在尝试将 LinkedList 放入 @Embeddable @ElementCollection 并给我： org.hibernate.MappingException
主要的：
public class Main
{
@SuppressWarnings({ "deprecation", "static-access" })
public static void main(String[] args)
{
AdvertiserDAO adD = new AdvertiserDAO();
Advertiser ad = new Advertiser();
Campaign c = new Campaign();
Action ac = new Action();
Calendar start = new GregorianCalendar();
Calendar end = new GregorianCalendar();
start.set(Calendar.DAY_OF_MONTH,8);
start.set(Calendar.MONTH,0);
start.set(Calendar.YEAR,2018);
start.set(Calendar.HOUR_OF_DAY,12);
start.set(Calendar.MINUTE, 0);
start.set(Calendar.SECOND, 0);
end.set(Calendar.DAY_OF_MONTH,1);
end.set(Calendar.MONTH,11);
end.set(Calendar.YEAR,2018);
end.set(Calendar.HOUR_OF_DAY,13);
end.set(Calendar.MINUTE, 30);
end.set(Calendar.SECOND, 10);
System.out.println("Start date: "+start.get(Calendar.DAY_OF_MONTH)+"/"+(start.get(Calendar.MONTH)+1)+"/"+start.get(Calendar.YEAR));
System.out.println("Start time: "+start.get(Calendar.HOUR_OF_DAY)+":"+start.get(Calendar.MINUTE)+":"+start.get(Calendar.SECOND));
System.out.println("End date: "+end.get(Calendar.DAY_OF_MONTH)+"/"+(end.get(Calendar.MONTH)+1)+"/"+end.get(Calendar.YEAR));
System.out.println("End time: "+end.get(Calendar.HOUR_OF_DAY)+":"+end.get(Calendar.MINUTE)+":"+end.get(Calendar.SECOND));
/*Set Action properties*/
ac.setStartDate(start);
ac.setEndDate(end);
ac.setId("1");
/*Set Campaign properties*/
c.addIdAction(ac.getId());
c.setStartDate(start);
c.setEndDate(end);
c.setDefaultURL("http://www.facebook.com");
/*Set advertiser properties*/
ad.setActive(true);
ad.setAdress("Fake street 123");
ad.setEmail("mail@gmail.com");
ad.setId("17");
ad.setName("Name Inc.");
ad.setPhone("000000000");
ad.setProduct("Product");
ad.setSector("IT");
ad.setDefaultURL("http://www.twitter.com");
ad.setSubSector("Software development");
ad.addCampaign(c);
System.out.println(ad);
adD.create(ad);
}
}
主要实体：
@Entity
public class Advertiser
{

private String id;

嵌入式类：
@Embeddable
public class Campaign
{
private Calendar startDate;

private String defaultURL;
private List<String> idActions;
//TODO: specific getters and setters, getDay, getMonth, getYear, getHour, getMinute, getSecond

}
public Calendar getStartDate() {
return startDate;
}
public void setStartDate(Calendar startDate) {
this.startDate = startDate;
}
public Calendar getEndDate() {
return endDate;
}
public void setEndDate(Calendar endDate) {
this.endDate = endDate;
}
public List<String> getIdAction() {
return idActions;
}
public void setIdAction(List<String> idAction) {
this.idActions = idAction;
}
public void addIdAction(String idAction)
{
if(this.idActions == null)
{
this.idActions = new LinkedList<String>();
}
this.idActions.add(idAction);
}
}
