使用maven管理项目

1.依赖包  

             
                  
       
        junit
                   
       
        junit
                   
       
        4.10
                   
       
        test
               
              
                  
       
        org.hibernate
                   
       
        hibernate-core
                   
       
        4.3.5.Final
               
              
                  
       
        org.hibernate
                   
       
        hibernate-c3p0
                   
       
        4.3.5.Final
               
          
     

     
         
              
       
        com.mysql.jdbc.Driver
               
       
        jdbc:mysql://127.0.0.1:3306/cl?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true
               
       
        root
               
               
       
        org.hibernate.dialect.MySQLDialect
               
       
        org.hibernate.connection.C3P0ConnectionProvider
               
       
        1
               
       
        3
               
       
        thread
               
       
        true
               
       
        update
               
           
      
     

3.hibernate 工厂类

public class HibernateUtil {    private static final SessionFactory sessionFactory = buildSessionFactory();    private static SessionFactory buildSessionFactory() {        try {            Configuration cfg = new Configuration().configure();            StandardServiceRegistry *** =new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()).build();            SessionFactory factory = cfg.buildSessionFactory(***);            return factory;        } catch (Throwable ex) {            System.err.println("Initial SessionFactory creation failed." + ex);            throw new ExceptionInInitializerError(ex);        }    }    public static SessionFactory getSessionFactory() {        return sessionFactory;    }    public static void schemaCreate() {        Configuration cf = new Configuration().configure();        SchemaExport se = new SchemaExport(cf);        se.create(true, true);    }    public static void schemaUpdate() {        Configuration cf = new Configuration().configure();        SchemaUpdate su = new SchemaUpdate(cf);        su.execute(false, true);    }    public static void schemaValidate() {        Configuration cf = new Configuration().configure();        SchemaValidator su = new SchemaValidator(cf);        su.validate();    }    public static void main(String[] args) {        schemaCreate();    }}

4.实体类，此处省略set/get方法

@Entity@Table(name = "t_h_user")public class User {             @Id    @GeneratedValue    private int id;    private String name;    private Date birthday;

5.测试

public class ch01 {    private static SessionFactory sf;    @BeforeClass    public static void befoe() {        sf = HibernateUtil.getSessionFactory();    }    @Test    public void test() {        User u = new User();        u.setName("chenlongccc");        u.setBirthday(new Date());                  Session session = sf.getCurrentSession();                  session.beginTransaction();        session.save(u);        session.getTransaction().commit();        //session.close();    }}
