MyEclipse，实体DAOFactory、Action、Form 引用资源

假设载入 Hibernate3 框架。

 

其中 HibernateSessionFactory.java 置于 org.stephencat.hibernate 中。

 

实体DAOFactory 引用资源如下：

 

Session session;  (Session 来自 org.hibernate.Session )

 

Transaction tx; (Transaction 来自 org.hibernate.Transaction)

 

DAOFactory方法示例：

 

public void add(Admin admin) throws HibernateException {
  try {
   session = HibernateSessionFactory.currentSession();
   tx = session.beginTransaction();
   // Add a new admin
   session.save(admin);
   tx.commit();
  } catch (HibernateException e) {
   throw e;
  } finally {
   if (tx != null) {
    tx.rollback();
   }
   HibernateSessionFactory.closeSession();
  }
 }

 

Action 方法示例如下：

 

// TODO Auto-generated method stub
  Admin admin = new Admin();
  admin.setName(addAdminForm.getName());
  admin.setPassword(addAdminForm.getPassword());
  AdminDAOFactory adminDAO = new AdminDAOFactory();
  adminDAO.add(admin);
  return mapping.findForward("success");

 

Form 引用资源如下：

 

ActionErrors errors = ......; (ActionErrors 和 ActionMessage 来自 org.apache.struts.action.*)

 

Session session = ......; (Session 来自 org.hibernate.Session )

Transaction tx = ......; (Transaction 来自 org.hibernate.Transaction )

Query query = ......; (Query 来自 org.hibernate.Query )

 

Iterator it = ......; (Iterator 来自 java.util.Iterator )

 

Form validate 方法示例：

 

ActionErrors errors = new ActionErrors();
Session session = HibernateSessionFactory.currentSession();
Transaction tx = session.beginTransaction();
Query query = session.createQuery("select admin from Admin as admin where admin.name='"+this.name+"'");
Iterator it = query.iterate();
if(it.hasNext()){
   errors.add("addAdmin.err.name",new ActionMessage("form.addAdmin.err.name"));
   
}
tx.commit();
HibernateSessionFactory.closeSession();
  
return errors;
