spring入門(12)-spring與hibernate整合完成增删改查的操作（繼承HibernateDaoSupport調用hibernateTemplate類）

本文是在上一篇博文的基礎之上，通過繼承HibernateDaoSupport調用hibernateTemplate類，隻要将UserDaoImpl.java改為繼承HibernateDaoSupport類，還有spring-dao.xml檔案加入對HibernateDaoSupport的配置bean即可，具體實作源碼如下：

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"

    </bean>
    <bean id="usersDaoImpl" class="www.csdn.spring.hibernate.dao.copy.UsersDaoImpl" parent="hibernateDaoSupport">
    	
    </bean>
 
</beans>
