package ctl.annotion.teacher;  
import org.hibernate.Session;  
import org.hibernate.SessionFactory;  
import org.hibernate.cfg.AnnotationConfiguration;  
public class OrcaleTeacherTestSessionFactory \{  
public static void main(String\[\] args) \{  
Teacher t = new Teacher();  
t.setName("ctl");  
t.setTitle("Ich liebe dich");  
SessionFactory sf = new AnnotationConfiguration().configure("Orcalehibernate.cfg.xml").buildSessionFactory();  
Session session = sf.openSession();  
session.beginTransaction();  
session.save(t);  
session.getTransaction().commit();  
session.close();  
sf.close();  
\}

package ctl.annotion.teacher;  
import javax.persistence.Column;  
import javax.persistence.Entity;//注意是javax.persistence  
import javax.persistence.GeneratedValue;  
import javax.persistence.GenerationType;  
import javax.persistence.Id;  
@Entity  
public class Teacher \{  
private int id;  
private String name;  
private String title;  
@Id//@Id在哪那个字段即为主键  
@GeneratedValue(strategy = GenerationType.AUTO) 在mysql中可以实现从1自增但是在orcale中虽然实现了自增但是不是从1开始行  
public int getId() \{  
return id;  
\}  
public void setId(int id) \{  
this.id = id;  
\}  
@Column  
public String getName() \{  
return name;  
\}  
public void setName(String name) \{  
this.name = name;  
\}  
@Column  
public String getTitle() \{  
return title;  
\}  
public void setTitle(String title) \{  
this.title = title;  
\}  
\}
