尝试持久化实体时出现DataException

标签: java hibernate jpa entity

我试图坚持一个实体:

        @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
        }

使用以下代码:

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:

我不明白为什么会发生这种情况,我只是听说当尝试使用大于指定(或默认值)的属性来保持Entity时抛出此异常。有人能指出我正确的方向吗?

答案 0 :(得分:1)

JPA数据类型本身不支持DateTime类,因此您需要替换它:

@Column
private DateTime date; 

以下内容:

@Column
@Temporal(TemporalType.DATETIME)
private java.util.Date date;
