ssh整合之HibernateDaoSupport的使用

继承HibernateDaoSupport有三种方式：

1.

Java代码



@Component("logDAO")

public class LogDAOImpl extends HibernateDaoSupport implements LogDAO {

public void save(Log log) {

this.getHibernateTemplate().save(log);

}

}

xml中注入：

Java代码



<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

Java代码



<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.

Java代码



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

Java代码



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);

}

}

Xml.xml代码



<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">

<property name="sessionFactory" ref="sessionFactory"></property>

</bean>

3继承sessionFactory

Java代码



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

Java代码



@Component

public class SuperDAO extends HibernateDaoSupport {

@Resource(name="hibernateTemplate")

public void setSuperHibernateTemplate(HibernateTemplate hibernateTemplate) {

super.setHibernateTemplate(hibernateTemplate);

}

}

Java代码



@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>
