# hibernate好好玩(2/26進來看)
###### tags: `hibernate`
2/26(五)下午4:30 Hibernate作業
專二專案 JDBC相關連線改成Hibernate

組長或技術長的組態檔設定好
但每個人還是要瞭解組態檔的相關參數

可以參考老師的opensessionfilter
把transaction交給此類別控管
這樣每個人的service就可以簡化

public class OpenSessionViewFilter implements Filter {

	@Override
	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
		SessionFactory factory = HibernateUtil.getSessionFactory();
		Session session = factory.getCurrentSession();

		try {
			session.beginTransaction();
			System.out.println("Transaction begin.");
			
			chain.doFilter(request, response);
			
			session.getTransaction().commit();
			System.out.println("Transaction Commit.");
		} catch (Exception e) {
			session.getTransaction().rollback();
			System.out.println("Transaction Rollbabk.");
			e.printStackTrace();
		} finally {
			System.out.println("Session Closed.");
		}
	}

參考老師的servletlistenser
另外加sessionFactory 開啟和關閉

public class SessionFactoryListener implements ServletContextListener {

	@Override
	public void contextDestroyed(ServletContextEvent sce) {
		HibernateUtil.closeSessionFactory();
		System.out.println("SessionFactory Closed.");
	}

	@Override
	public void contextInitialized(ServletContextEvent sce) {
		HibernateUtil.getSessionFactory();
		System.out.println("SessionFactory Created.");
	}
   
}

組員用自己table
每組交一個專案

大家加油
