新建vo类：

@Entity
@Table(name="t_user")
public class User implements Serializable{
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id;
    private String name;
    private int age;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}

新建dao类：

public class UserDaoImpl implements UserDao{
    private SessionFactory sessionFactory;
    public List<User> findAll() {
        return sessionFactory.getCurrentSession().createQuery("from User").list();
    }
    public int save(User user) {
        try {
            sessionFactory.getCurrentSession().save(user);
            return 1;
        } catch (HibernateException e) {
            e.printStackTrace();
        }
        return -1;
    }
    public int delete(User user) {
        try {
            sessionFactory.getCurrentSession().delete(user);
            return 1;
        } catch (HibernateException e) {
            e.printStackTrace();
        }
        return -1;
    }
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

新建service类：

public class UserServiceImpl implements UserService {
    private UserDao userDao;
    public List<User> findAll() {
        return userDao.findAll();
    }
    public int save(User user) {
         return userDao.save(user);
    }
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
}

新建action类：

public class UserAction {
    private List<User> list;
    private UserService userService;
    public String list(){
        list = userService.findAll();
        return Action.SUCCESS;
    }
    public List<User> getList() {
        return list;
    }
    public void setList(List<User> list) {
        this.list = list;
    }
    public UserService getUserService() {
        return userService;
    }
    public void setUserService(UserService userService) {
        this.userService = userService;
    }
}

                PROPAGATION_MANDATORY 支持当前事务，如果当前没有事务，就抛出异常。
                PROPAGATION_REQUIRES_NEW 新建事务，如果当前存在事务，把当前事务挂起。
                PROPAGATION_NOT_SUPPORTED 以非事务方式执行操作，如果当前存在事务，就把当前事务挂起。
                PROPAGATION_NEVER 以非事务方式执行，如果当前存在事务，则抛出异常。
                PROPAGATION_NESTED 如果当前存在事务，则在嵌套事务内执行。如果当前没有事务，则进行与PROPAGATION_REQUIRED类似的操作。
