spring入門(（12） spring與hibernate整合完成增刪改查的操作

本文是在上一篇博文的基礎之上，通過繼承HibernateDaoSupport調用hibernateTemplate類，只要將UserDaoImpl.java 改為繼承HibernateDaoSupport類，還有spring-dao.xml文件加入對HibernateDaoSupport的配置bean即可，具體實現源碼如 下：

UserDaoImpl.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);  
              
    }  
      
}

spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans  
           http://www.springframework.org/schema/beans/spring-beans.xsd">  
         
        
    <bean id="hibernateDaoSupport" class="org.springframework.orm.hibernate3.support.HibernateDaoSupport" 

abstract="true">  
    <property name="hibernateTemplate" ref="hibernateTemplate">  
    </property>  
    </bean>  
    <bean id="usersDaoImpl" class="www.csdn.spring.hibernate.dao.copy.UsersDaoImpl" 

parent="hibernateDaoSupport">  
              
    </bean>  
       
</beans>
