Hibernate------增删改查-----2 (Hibernate整合Spring)

本文是在上一篇博文的基础之上，通过继承HibernateDaoSupport调用hibernateTemplate类，只要将UserDaoImpl.java改为继承HibernateDaoSupport类，还有spring-dao.xml文件加入对HibernateDaoSupport的配置bean即可，具体实现源码如下：

UserDaoImpl.java

[java]
package www.csdn.spring.hibernate.dao.copy; 
 
import java.util.List; 
 
import org.springframework.orm.hibernate3.HibernateTemplate; 
import org.springframework.orm.hibernate3.support.HibernateDaoSupport; 
 
import www.csdn.spring.hibernate.domain.Users; 
 
public class UsersDaoImpl extends HibernateDaoSupport implements UsersDao{ 
     
    @Override 
    public void save(Users entity) { 
        getHibernateTemplate().save(entity); 
         
    } 
    @Override 
    public List<Users> getObjects(Class clazz) { 
         
        return getHibernateTemplate().find("from "+clazz.getName()); 
    } 
 
    @Override 
    public void deleteById(Class clazz,Integer id) { 
        //getHibernateTemplate().delete(hibernateTemplate.get(clazz.getName(), id));  
        getHibernateTemplate().bulkUpdate("delete from "+clazz.getName()+" where id="+id); 
    } 
 
    @Override 
    public void update(Users entity) { 
        getHibernateTemplate().update(entity); 
         
    } 
 
} 

package www.csdn.spring.hibernate.dao.copy;

import java.util.List;

import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

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

public class UsersDaoImpl extends HibernateDaoSupport implements UsersDao{
 
 @Override
 public void save(Users entity) {
  getHibernateTemplate().save(entity);
  
 }
 @Override
 public List<Users> getObjects(Class clazz) {
  
  return getHibernateTemplate().find("from "+clazz.getName());
 }

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

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

}
