利用hibernate更新数据库插入时间类型

[jsgpt003]

直接上代码 很简单一个model

@Entity
@Table(name="teacher")
public class Teacher {
	private Long id;
	private String teacheNo;
	private String teacheName;
	private TeacherTitle title;
	private Date regDate;
	
	@Id
	@Column(name="teacherId")
	public Long getId() {
		return id;
	}
	public void setId(Long id) {
		this.id = id;
	}
	public String getTeacheNo() {
		return teacheNo;
	}
	public void setTeacheNo(String teacheNo) {
		this.teacheNo = teacheNo;
	}
	public String getTeacheName() {
		return teacheName;
	}
	public void setTeacheName(String teacheName) {
		this.teacheName = teacheName;
	}
	@Enumerated(EnumType.STRING)
	public TeacherTitle getTitle() {
		return title;
	}
	public void setTitle(TeacherTitle title) {
		this.title = title;
	}
	@Temporal(TemporalType.TIMESTAMP)
	public Date getRegDate() {
		return regDate;
	}
	public void setRegDate(Date regDate) {
		this.regDate = regDate;
	}

save方法：

	@Test
	public void testTeacherSave() {
	
		Teacher t = new Teacher();
		t.setId(3L);
		t.setRegDate(new Date());
		t.setTeacheName("王氏");
		t.setTeacheNo("R0004");
		t.setTitle(TeacherTitle.高级);
		
		Session session = sessionFactory.getCurrentSession();
		session.beginTransaction();
		session.save(t);
		session.getTransaction().commit();
	}

疑问：
我save(Teacher t)时，在mysql数据库中regDate存入的数据格式为：2014-4-13 11:13:19
在sql2005保存的数据格式为：2014/4/13 11:13:19

请问 如何在sql2005中保存的时间格式也是yyyy-MM-dd HH:mm:ss
