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

[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 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 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);

}

}
