新建个dal层 专门操作数据库的一些方法，由于是测试学习。。没有考虑代码的规范和其他的问题。运行只看效果。
package jsftest.dal;
import org.hibernate.*;
import org.hibernate.cfg.*;
import org.apache.log4j.*;
import jsftest.vo.ArticleVO;
import java.util.*;
public class ArticleDAL {
org.apache.log4j.Logger log=Logger.getLogger(this.getClass());
private Session session=null;
public ArticleDAL() {
}
public void saveArticle(ArticleVO vo)
{
try
{
session = this.getSession();
session.saveOrUpdate(vo);
session.flush();
session.connection().commit();
session.close();
}
catch(Exception ee)
{
log.error(ee);
}
}
public void deleteArticle(int articleID)
{
session=this.getSession();
ArticleVO vo=(ArticleVO)session.get(ArticleVO.class,articleID);
session.delete(vo);
}
public void deleteArticle(ArticleVO vo)
{
session= this.getSession();
session.delete(vo);
session.flush();
}
public List LoadArticleAll()
{
session=this.getSession();
Query query=session.createQuery("FROM ArticleVO");
List list= query.list();
session.close();
return list;
}
public Session getSession()
{
try
{
Configuration cfg = new Configuration().configure();
SessionFactory sf = cfg.buildSessionFactory();
return sf.openSession();
} catch(Exception ee)
{
log.error("error:" + ee.getMessage());
}
return null;
}
}
新建from 类 前途jsf都是掉这类的方法
package jsftest.from;
import java.util.ArrayList;
import java.util.List;
import javax.faces.component.UIData;
import javax.faces.event.ActionEvent;
import jsftest.dal.ArticleDAL;
import jsftest.vo.ArticleVO;
import java.util.Collection;
public class ArticleForm {
private int id=0;
private String title;
private String body;
private ArrayList articles;
public ArticleForm() {
loadall();
}
private ArticleDAL dal=new ArticleDAL();
public void save()
{
ArticleVO vo=new ArticleVO();
vo.setBody(this.getBody());
vo.setTitle(this.getTitle());
if(this.getId()!=0)
{
vo.setId(this.getId());
}
dal.saveArticle(vo);
}
public void edit(ActionEvent event)
{
UIData table = (UIData) event.getComponent().getParent().getParent();
ArticleVO vo=new ArticleVO();
vo=(ArticleVO)table.getRowData();
this.setBody(vo.getBody());
this.setId(vo.getId());
this.setTitle(vo.getTitle());
}
public void delete(ActionEvent event)
{
UIData table = (UIData) event.getComponent().getParent().getParent();
ArticleVO vo=(ArticleVO)table.getRowData();
dal.deleteArticle(vo);
dal.LoadArticleAll();
}
public void loadall()
{
this.setArticles((ArrayList)dal.LoadArticleAll());
}
public String getBody() {
return body;
}
public int getId() {
return id;
}
public String getTitle() {
return title;
}
public Collection getArticles() {
//this.loadall();
if(articles==null)
{
articles=new ArrayList();
}
return articles;
}
public void setBody(String body) {
this.body = body;
}
public void setId(int id) {
this.id = id;
}
public void setTitle(String title) {
this.title = title;
}
public void setArticles(ArrayList articles) {
this.articles = articles;
}
}
实体
package jsftest.vo;
public class ArticleVO {
private int id;
private String title;
private String body;
public ArticleVO() {
}
//getter setter
