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) {
