首先編寫可持久化的實體

@Entity
@Table(name = "Stock")
public class Stock {
    @Id //標識實體中ID和底層資料表的主鍵統一
    @GeneratedValue
    private int id;     //股票編號
    @Column
    private String name;//股票名稱   
    @Column
    private int count;  //股數

    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 getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }
}
 

public interface IStockDAO {
    public int addStock(Stock stock);
}

@Repository("stockDAO")
public class StockDAOImpl implements IStockDAO {
    //dao植入SessionFactory變數  重量級
    @Autowired
    private SessionFactory sessionFactory;

    public int addStock(Stock stock) {
        System.out.println(sessionFactory+"========================");
        Session session = sessionFactory.getCurrentSession();
        Serializable count=session.save(stock);
        Integer cc=(Integer)count;
        return cc.intValue();
    }
}
 

public interface IStockService {
    public int saveStock(Stock stock);
}

@Service("stockService")

    //植入dao的介面變數
    @Resource(name = "stockDAO")
    private IStockDAO dao;
    @Transactional
    public int saveStock(Stock stock) {
        return dao.addStock(stock);
    }
}
 

@Controller
@Scope(value = "prototype")
@ParentPackage("struts-default")
@Namespace("/")

        }
    }
    public Stock getModel() {
        return stock;
