Java 尝试持久化实体时出现DataException

我正在尝试持久化一个实体：

        @Entity
        @Table(name = "note")
        public class Note extends AbstractEntity {

        @Column
        private String content;

        @Column
        private DateTime date;

        @ManyToOne
        @JoinColumn(nullable=false)
        private Interviewer author;

        @ManyToOne
        @JoinColumn(nullable=false)
        private Interviewer interviewer;

        //getters & setters
        }

代码如下：

Note noteToPersist = new Note();
noteToPersist.setAuthor(interviewerDao.findInterviewerByLdapId("ldap_id"));
noteToPersist.setInterviewer(interviewerDao.findInterviewerByLdapId(request.getLdap()));
noteToPersist.setContent(note.getContent());
noteToPersist.setDate(new DateTime());
notesToSave.add(noteDao.create(noteToPersist));

然而，我得到的是：
