<hibernate-configuration> <session-factory> <!-- properties --> <property name="connection.username"> root </property> <property name="connection.url"> jdbc:mysql://localhost:3306/tonnyblog </property> <property name="dialect"> net.sf.hibernate.dialect.MySQLDialect </property> <property name="connection.password"></property> <property name="connection.driver_class"> org.gjt.mm.mysql.Driver </property> <!-- mapping files --> <mapping resource="com/tonny/blog/bean/User.hbm.xml"/> <mapping resource="com/tonny/blog/bean/Item.hbm.xml"/> <mapping resource="com/tonny/blog/bean/Review.hbm.xml"/> </session-factory></hibernate-configuration> mapping為JAVABEAN所對應的映射。 下面我們繼續HIBERNATE程序的下步編寫： import net.sf.hibernate.HibernateException; import net.sf.hibernate.Session; import net.sf.hibernate.SessionFactory; import net.sf.hibernate.cfg.Configuration; /** * Description of the Class * * @author tonny * @created 2004年2月6日 */public class HibernateUtil { private final static SessionFactory sessionFactory; static { try { sessionFactory = new Configuration().configure().buildSessionFactory(); } catch (HibernateException ex) { throw new RuntimeException( "Exception building SessionFactory: " + ex.getMessage(),ex); } } private HibernateUtil(){ } /** * Description of the Field */ private final static ThreadLocal session = new ThreadLocal(); /** * Description of the Method * * @return Description of the Return Value * @exception HibernateException Description of the Exception */ public static Session currentSession() throws HibernateException { Session s = (Session) session.get(); if (s == null) { s = sessionFactory.openSession(); session.set(s); } return s; } /** * Description of the Method * * @exception HibernateException Description of the Exception */ public static void closeSession() throws HibernateException { Session s = (Session) session.get(); session.set(null); if (s != null) { s.close(); } } public static void init() { } } 創建sessionFactory import net.sf.hibernate.HibernateException; import net.sf.hibernate.SessionFactory; import net.sf.hibernate.cfg.Configuration; import org.apache.struts.action.ActionServlet; import org.apache.struts.action.PlugIn; import org.apache.struts.config.ModuleConfig; import com.tonny.blog.dao.hibernate.HibernateUtil; public class HibernatePlugin implements org.apache.struts.action.PlugIn { public void init(ActionServlet servlet, ModuleConfig config) { HibernateUtil.init(); } public void destroy() { try { HibernateUtil.closeSession(); } catch(HibernateException hex) { hex.printStackTrace(); } } } 以上為HIBERNATE基本配置，對數據庫操作采用DAO模式，增加配置如下： import com.tonny.blog.dao.hibernate.*; public class DAOFactory { private static DAOFactory instance; public synchronized static DAOFactory getInstance() { if (instance == null) { instance = new DAOFactory(); } return instance; } private DAOFactory() { } public ItemDAO getItemDAO() { return new ItemDAOHibernate(); } public ReviewDAO getReviewDAO() { return new ReviewDAOHibernate(); } public UserDAO getUserDAO() { return new UserDAOHibernate(); } } struts.xml增加配置： <controller contentType="text/html" debug="3" locale="true" nocache="true" processorClass= "com.tonny.blog.struts.controller.IndexRequestProcessor"/> <message-resources parameter="com.tonny.resource"/> <plug-in className= "com.tonny.blog.struts.plugin.HibernatePlugin"/> <plug-in className="org.apache.struts.tiles.TilesPlugin"> <set-property property="moduleAware" value="true"/> <set-property property="definitions-debug" value="0"/> <set-property property="definitions-parser-details" value="0"/> <set-property property="definitions-parser-validate" value="false"/> <set-property property="definitions-config" value="/WEB-INF/title-def.xml"/> </plug-in> 下面我們定義服務層： public class ServiceFactory { private static ServiceFactory instance; public synchronized static ServiceFactory getInstance() { if (instance == null) { instance = new ServiceFactory(); } return instance; } private ServiceFactory() { } public IService getService() { return new ServiceImp(); } } import com.tonny.blog.struts.form.*; import com.tonny.blog.view.*; import com.tonny.blog.bean.*; import java.util.*; import javax.servlet.http.*; public interface IService { public UserContainer login(UserForm userForm); public boolean logout(UserContainer userContainer); public boolean addBlog(BlogForm blogForm,String filePath); public boolean removeBlog(Long id); public boolean addReview(Long topicId,ReviewForm reviewForm); public boolean updateBlog(Long id,String conten,String topic); public boolean removeReview(Long id); public List getItems(); public ItemView getItem(Long id); public ItemView getEditItem(Long id); public List search(SearchForm searchForm); /** * @param id * @param userForm */ public boolean addUser(UserForm userForm); } import com.tonny.blog.struts.form.*; import com.tonny.blog.view.*; import com.tonny.blog.dao.*; import com.tonny.blog.bean.*; import java.util.*;import javax.servlet.http.*; import com.tonny.blog.struts.util.FileUpload; public class ServiceImp implements IService { public UserContainer login(UserForm userForm) { UserDAO userDAO=DAOFactory.getInstance().getUserDAO(); User user=userDAO.loadUser(userForm.getName()); if(user==null)return new UserContainer("",false); if(!user.getPassword().equals(userForm.getPassword())) return new UserContainer("",false); return new UserContainer(userForm.getName(),true); } public boolean logout(UserContainer userContainer) { userContainer.setLogin(false); userContainer.setName(""); return true; } public boolean addBlog(BlogForm blogForm,String path) { ItemDAO itemDAO=DAOFactory.getInstance().getItemDAO(); Item item=new Item(blogForm.getTopic(), blogForm.getContent(), FileUpload.upload(blogForm.getFile(),path),new Date()); itemDAO.addItem(item); return true; } public boolean removeBlog(Long id) { ReviewDAO reviewDAO=DAOFactory.getInstance( |
