StringBuffer sql=new StringBuffer("SELECT * FROM edu_video");
sql.append(" WHERE videoPath = '" + videoPath + "'");
Query query = getSession().createSQLQuery(sql.toString());
query.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP);
或
StringBuffer sql=new StringBuffer("SELECT * FROM edu_video");
sql.append(" WHERE videoPath = '" + videoPath + "'");
Query query = getSession().createSQLQuery(sql.toString());
query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
其下为遍历
if(query.list() != null && query.list().size() > 0) {
Map<String, Object> map = (Map<String, Object>) query.list().get(0);
return map;
}
Hibernate执行sql 修改
String sql="update EduVideo video set video.online="+online+" where video.videoPath='"+videoPath+"'";
Query query = getSession().createQuery(sql);
query.executeUpdate();
package com.aowin.dao;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.aowin.model.User;
public class UserDao extends HibernateDaoSupport implements IUserDao{
public User findByUsernameAndPassword(String username, String password){
String hql = "from com.aowin.model.User u where u.username=? and u.password=?";
// Query query = this.getSession().createQuery(hql);
// query.setString(0, username);
// query.setString(1, password);
// List list = query.list();
List list = this.getHibernateTemplate().find(hql, new Object[]{username, password});
if(list.isEmpty()){
return null;
}else{
return (User) list.get(0);
}
}
public void deleteById(Integer id) {
// User user = (User) this.getSession().get(User.class, id);
// this.getSession().delete(user);
User user = (User) this.getHibernateTemplate().get(User.class, id);
this.getHibernateTemplate().delete(user);
}
public List<User> findAll() {
String hql = "from com.aowin.model.User";
// return this.getSession().createQuery(hql).list();
return this.getHibernateTemplate().find(hql);
}
public User findById(Integer id) {
return (User) this.getHibernateTemplate().get(User.class, id);
}
public void save(User user) {
this.getHibernateTemplate().save(user);
}
public void update(User user) {
this.getSession().update(user);
}
}
