action:

biz实现类：

@Transactional(propagation=Propagation.REQUIRED)
@Service("cbiz")
public class carbizimpl implements carbiz{
@Autowired
@Qualifier("cdao")
private cardao cd;
public cardao getCd() {
return cd;
}
public void setCd(cardao cd) {
this.cd = cd;
}
public List<Car> carall() {
// TODO Auto-generated method stub
return cd.carall();
}
public int decar(int id) {
// TODO Auto-generated method stub
return cd.decar(id);
}
public List<Cartyper> ct() {
// TODO Auto-generated method stub
return cd.ct();
}
public int sa(Car c) {
// TODO Auto-generated method stub
return cd.sa(c);
}
public List<Car> queryForPage(int offset, int length) {
// TODO Auto-generated method stub
return cd.queryForPage(offset, length);
}
public int getcount() {
// TODO Auto-generated method stub
return cd.getcount();
}
public Car car(int id) {
// TODO Auto-generated method stub
return cd.car(id);
}
public int up(Car c) {
// TODO Auto-generated method stub
return cd.up(c);
}

 

dao实现类：

@Repository("cdao")
public class cardaoimpl extends HibernateDaoSupport implements cardao{
@Resource(name = "sessionFactory")
public void setSuperSessionFactory(SessionFactory sessionFactory) {
super.setSessionFactory(sessionFactory);
}
public List<Car> carall() {
HibernateTemplate ht=this.getHibernateTemplate();

return ht.find("from Car");

}
public int decar(int id) {
int i=0;
HibernateTemplate ht=this.getHibernateTemplate();
Car car=ht.load(Car.class, id);
try {
ht.delete(car);
} catch (DataAccessException e) {
// TODO Auto-generated catch block
i=1;
}
return i;
}
public List<Cartyper> ct() {
HibernateTemplate ht=this.getHibernateTemplate();
return ht.find("from Cartyper");
}
public int sa(Car c) {
int j=0;
// TODO Auto-generated method stub
try {
this.getHibernateTemplate().save(c);
} catch (DataAccessException e) {
j=1;
}
return j;
}
public List<Car> queryForPage(int offset, int length) {
Session session=this.getHibernateTemplate().getSessionFactory().openSession();
Query q = session.createQuery("from Car");
q.setFirstResult((offset-1)*length);
q.setMaxResults(length);
return q.list();
}
public int getcount() {
Session session=this.getHibernateTemplate().getSessionFactory().openSession();
Query q = session.createQuery("select count(*) from Car");
return Integer.parseInt(q.list().get(0).toString());
}
public Car car(int id) {
HibernateTemplate ht=this.getHibernateTemplate();

return (Car) ht.find("from Car where id=?",id).get(0);
}
public int up(Car c) {
int i=0;
HibernateTemplate ht=this.getHibernateTemplate();
Car cc=(Car) ht.find("from Car where id=?",c.getId()).get(0);
try {
cc.setBrand(c.getBrand());
cc.setPrice(c.getPrice());
cc.setCartyper(c.getCartyper());
} catch (Exception e) {
i=1;
}

return i;
}
