SSH注解整合

首先是实体类中的注解：

@Entity
@Table(name = "Stock")
public class Stock {
    @Id //标识实体中ID和底层数据表的主键统一
    @GeneratedValue(strategy = GenerationType.IDENTITY)   //主键生成策略：mysql 底层自动autoincreament
    private int sid;     //股票编号
    private String sname;//股票名称   YYM教育
    @Column(name="scount")
    private int scount;  //股数

    public int getSid() {
        return sid;
    }

    public void setSid(int sid) {
        this.sid = sid;
    }

    public String getSname() {
        return sname;
    }

    public void setSname(String sname) {
        this.sname = sname;
    }

    public int getScount() {
        return scount;
    }

    public void setScount(int scount) {
        this.scount = scount;
    }
}

然后就是dao层中注解：

@Repository("stockDAO")
public class StockDAOImpl implements IStockDAO {
    //dao植入SessionFactory变量  重量级
    //使用自动装配让SessionFactory
    @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();
    }

}

之后就是service中的注解：

@Service("stockService")
public class StockServiceImpl implements IStockService {
    //植入dao的接口变量
    @Resource(name = "stockDAO")
    private IStockDAO dao;
    @Transactional
    public int saveStock(Stock stock) {
        return dao.addStock(stock);
    }
}

然后就是action连接service

@Controller
@Scope(value = "prototype")
@ParentPackage("struts-default")
@Namespace("/")
public class StockAction extends ActionSupport implements ModelDriven<Stock> {
   //Entity变量
    private Stock stock;
    @Resource(name = "stockService")
    private IStockService service;

    public StockAction(){
        stock=new Stock();
    }
    @Action(value = "addStock",results = {@Result( name = "success",location = "/success.jsp"),@Result(name="input",location = "/add.jsp")})
    public String execute() throws Exception {
        int count = service.saveStock(stock);
        if (count>0) {
            return SUCCESS;
        }else {
            return INPUT;
        }
    }
    public Stock getModel() {
        return stock;
    }
}
