HibernateTemplate的常用方法简介

HibernateTemplate的常用方法简介：
void delete(Object entity)：删除指定持久化实例
deleteAll(Collection entities)：删除集合内全部持久化类实例
find(String ueryString)：根据HL查询字符串来返回实例集合
findByNameduery(String ueryName)：根据命名查询返回实例集合
get(Class entityClass, Serializable id)：根据主键加载特定持久化类的实例
save(Object entity)：保存新的实例
saveOrUpdate(Object entity)：根据实例状态，选择保存或者更新
update(Object entity)：更新实例的状态，要求entity是持久状态
setMaxResults(int maxResults)：设置分页的大小

 

public void save(Teacher teacher) { 
this.hibernateTemplate.save(teacher); 
} 
 public void update(Teacher teacher) { 
 this.hibernateTemplate.update(teacher); 
} 

 public void delete(Teacher teacher) { 
 this.hibernateTemplate.delete(teacher); 
} 

   public Teacher getTeacherById(Long id) {  

    return (Teacher)this.hibernateTemplate.get(Teacher.class, id);  
}  
  
public Teacher getTeacherById(Long id) {  

     return (Teacher)this.hibernateTemplate.load(Teacher.class, id);  
 }  


  public Iterator getTeachersByAge(int age) {  
  Iterator iterator = null;  
      
   //使用find方法  
    List list = (List)this.hibernateTemplate().find("from Teacher t where t.age>?", new Integer(age));  
    iterator = list.iterator();  
      
    //使用iterator方法  
    iterator = this.hibernateTemplate().iterate("from Teacher t where t.age>?", new Integer(age));  
       
    return iterator;  
 }
