spring入门(11)-spring与hibernate整合完成增删改查的操作（封装HibernateTemplate模版类对象） (二)

package www.csdn.spring.hibernate.dao;

import java.util.List;

import org.springframework.orm.hibernate3.HibernateTemplate;

import www.csdn.spring.hibernate.domain.Users;

public class UsersDaoImpl implements UsersDao{
// 封装模版类对象
private HibernateTemplate hibernateTemplate;

// 注入
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}

@Override
public void save(Users entity) {
hibernateTemplate.save(entity);

}
@Override
public List getObjects(Class clazz) {

return hibernateTemplate.find("from "+clazz.getName());
}

@Override
public void deleteById(Class clazz,Integer id) {
//hibernateTemplate.delete(hibernateTemplate.get(clazz.getName(), id));
hibernateTemplate.bulkUpdate("delete from "+clazz.getName()+" where id="+id);
}

@Override
public void update(Users entity) {
hibernateTemplate.update(entity);

}

}
