测试代码：
public void testSelectInsertInvitation(){
Session session = HibernateSessionFactory.getSession();
Transaction transaction = session.beginTransaction();
Member member = (Member)session.get(Member.class, 2);
Set<Invitation> invitations = member.getSendInvitations();
for ( Invitation invitation : invitations) {
System.out.println(invitation.getContent());
System.out.println("帖子内容是: "+invitation.getContent()+" 时间是 : "+invitation.getInvitationDate());
}
transaction.commit();
HibernateSessionFactory.closeSession();
}
