开发工具采用MYECLIPS3.6,首先是建立项目,导入STRUTS+HIBERNATE包,然后配置SRC跟目录下的hibernate.cfg.xml.我采用的是MYSQL数据库,所以配置如下:
<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为JAVABEAN所对应的映射。
下面我们继续HIBERNATE程序的下步编写
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(){
} } 创建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(); }
}
} 以上为HIBERNATE基本配置,对数据库操作采用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> 下面我们定义服务层:
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) { &[1] [2] [3] 下一页 没有相关教程
