SSH程序框架的整合

Posted 2020-09-08

spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现

　　Spring整合Hibernate有什么好处？

　　1、由IOC容器来管理Hibernate的SessionFactory

　　2、让Hibernate使用上Spring的声明式事务

xml:

那什么我们先创建一个账户，再把jar包导一下：

Stock：

public class Stock {
     private Integer sid;
     private String sname;
     private Integer scount;
 
     public Stock(String sname, Integer scount) {
         this.sname = sname;
         this.scount = scount;
     }
 
     public Integer getSid() {

     }

         return scount;
     }
 
     public void setScount(Integer scount) {
         this.scount = scount;
     }
 }
StockDao：

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

StockDaoImpl：

public class StockDaoImpl implements StockDao {
     private SessionFactory sessionFactory;
     public int addStock(Stock stock) {
         Session session = sessionFactory.getCurrentSession();
         Serializable count = session.save(stock);
         return (Integer)count;
     }
     public SessionFactory getSessionFactory() {
         return sessionFactory;
     }
     public void setSessionFactory(SessionFactory sessionFactory) {
         this.sessionFactory = sessionFactory;
     }
 }

AccountService：

public interface AccountService {
     public int addStock(Stock stock); 
 }
service：

public class AccountServiceImpl implements AccountService {
     private StockDao stockDao;
     @Transactional
     public int addStock(Stock stock) {
         return stockDao.addStock(stock);
     }
     public StockDao getStockDao() {
         return stockDao;
     }
     public void setStockDao(StockDao stockDao) {
         this.stockDao = stockDao;
     }
 }

测试：

public class SSHTest {
    @Test
    public void tsstAddstock(){
        ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
        IAccountService service=(IAccountService)ctx.getBean("stockService");
        Stock stock=new Stock("昨天的故事",10);
        service.addStock(stock);
    }
}
好了，如果你是这样做的，那么可以看看数据库你想要的了！！！！
