package cn.zdxh.test; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; import org.junit.Test; import cn.zdxh.domain.Customer; public class CustomerTest { @Test public void insertTest(){ //1.加载hibernate.cfg.xml Configuration config=new Configuration().configure(); //2.获取SessionFactory SessionFactory sessionFactory=config.buildSessionFactory(); //3.得到session Session session=sessionFactory.openSession(); //4.开启事务 Transaction t=session.beginTransaction(); //5.操作 Customer c=new Customer(); c.setName("里斯"); c.setAge(19); c.setCity("北京"); c.setSex("男"); //6.将数据存储到表中 session.save(c); //7.提交事务 t.commit(); //8.关闭资源 session.close(); sessionFactory.close(); } @Test public void deleteTest(){ //1.加载hibernate.cfg.xml Configuration config=new Configuration().configure(); //2.获取SessionFactory SessionFactory sessionFactory=config.buildSessionFactory(); //3.得到session Session session=sessionFactory.openSession(); //4.开启事务 Transaction t=session.beginTransaction(); //5.删除操作 Customer c=session.get(Customer.class, 1); //6。在表中删除 session.delete(c); //7.提交事务 t.commit(); //8.关闭资源 session.close(); sessionFactory.close(); } @Test public void updateTest(){ //1.加载hibernate.cfg.xml Configuration config=new Configuration().configure(); //2.获取SessionFactory SessionFactory sessionFactory=config.buildSessionFactory(); //3.得到session Session session=sessionFactory.openSession(); //4.开启事务 Transaction t=session.beginTransaction(); //5.修改操作，查询获取记录到实体类 Customer c=session.get(Customer.class, 2); c.setAge(28); c.setCity("shzh"); c.setName("貂蝉"); c.setSex("女"); //6。在表中修改 session.update(c); //7.提交事务 t.commit(); //8.关闭资源 session.close(); sessionFactory.close(); } }
