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; } }
