ssh 注解整合

Hibernate注解：取代hbm.xml文件
Spring注解：取代和tx
Struts注解：取代>

取代hbm.xml映射文件
    

@Entity //取代<class name="User"
@Table(name="t_user") //取代table="t_user">
public class User {

    @Id    //取代<id name="id">
    @GeneratedValue(strategy=GenerationType.AUTO) //取代<generator class="native">
    private int id;
    private String username;    //默认可以不配置
    //@Column(name="",length=3,nullable=true,unique=true)
    private String password;
}

取代和tx管理

@Repository //<bean id="userDao" class="cn.itcast.ssh.dao.UserDao">
public class UserDao {

    @Autowired
    private HibernateTemplate hibernateTemplate ;

    public void save(User user) {
        this.hibernateTemplate.save(user);
    }
}

@Service //<bean id="userService"
@Transactional  //添加事务管理
public class UserService {

    @Autowired    //<property name="userDao"
    private UserDao userDao;

    public void regist(User user) {
        this.userDao.save(user);
    }
}
