ssh整合之HibernateDaoSupport的使用

继承HibernateDaoSupport有三种方式：

1.

@Component("logDAO")
public class LogDAOImpl extends HibernateDaoSupport implements LogDAO {
    public void save(Log log) {
        this.getHibernateTemplate().save(log);
    }
}

    xml中注入：

<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
      <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>

 <bean id="logDao" class="com.zchen.spring.LogDaoImpl">
      <property name="hibernateTemplate" ref="hibernateTemplate"></property>
 </bean>

   也可以直接注入SessionFactory

<bean id="logDao" class="com.zchen.spring.LogDaoImpl">
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>

 这样一来每个daoImpl都要在bean.xml中注入所以第二种方式就是：

2.

import javax.annotation.Resource;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Component;
@Component
public class SuperDAO {
    private HibernateTemplate hibernateTemplate;
    public HibernateTemplate getHibernateTemplate() {
        return hibernateTemplate;
    }
    @Resource
    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }


}

 

    所有的daoImpl都继承自SuperDao

package com.zchen.dao.impl;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Component;
import com.zchen.dao.UserDAO;
import com.zchen.model.User;
@Component("urseDao") public class UserDAOImpl extends SuperDAO implements UserDAO {
    public void save(User user) {
        this.getHibernateTemplate().save(user);
    }
}

 

<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
      <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>

 3继承sessionFactory

import javax.annotation.Resource;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Component;
@Component
public class SuperDAO extends HibernateDaoSupport {
    @Resource(name="sessionFactory")
    public void setSuperSessionFactory(SessionFactory sessionFactory) {
        super.setSessionFactory(sessionFactory);
    }
}

   继承hibernateTemplate也是一样的

@Component
public class SuperDAO extends HibernateDaoSupport {


    @Resource(name="hibernateTemplate")
    public void setSuperHibernateTemplate(HibernateTemplate hibernateTemplate) {
        super.setHibernateTemplate(hibernateTemplate);
    }


}

  

 

@Component("u")
public class UserDAOImpl extends SuperDAO implements UserDAO {
    public void save(User user) {
        this.getHibernateTemplate().save(user);
    }
}

 如果继承hibernateTemplate要配置bean

 

  <bean id="userDao" class="com.zchen.spring.UserDaoImpl">
   <property name="hibernateTemplate" ref="hibernateTemplate"></property>
 </bean>
