spring入门(12)-spring与hibernate整合完成增删改查的操作（继承HibernateDaoSupport调用hibernateTemplate类）

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

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{@Overridepublic void save(Users entity) {getHibernateTemplate().save(entity);}@Overridepublic List<Users> getObjects(Class clazz) {return getHibernateTemplate().find("from "+clazz.getName());}@Overridepublic void deleteById(Class clazz,Integer id) {//getHibernateTemplate().delete(hibernateTemplate.get(clazz.getName(), id));getHibernateTemplate().bulkUpdate("delete from "+clazz.getName()+" where id="+id);}@Overridepublic 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>
