dao配置：注解配置

@Service
public class Dao {
@Resource
private SessionFactory sessionfactory;

@Transactional
public void addUser(User user){
Session session = sessionfactory.getCurrentSession();
session.save(user);

}
}

测试

public class BlogTest {
private ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");

@Test
public void testUser(){

User user = new User("赵六","sdfs","asf","fdd","dd");
Dao dao = (Dao) ac.getBean("dao");
dao.addUser(user);

}
}
