使用Hibernate模板持久化对象

1、配置数据源

<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:annotation-config />
<context:component-scan base-package="main.java.com">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="url"
value="jdbc:mysql://localhost:3306/usermanager?useUnicode=true&characterEncoding=UTF-8">
</property>
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="username" value="root"></property>
<property name="password" value="liketing"></property>
<!--连接池启动时的初始值-->
<property name="initialSize" value="1" />
<!--连接池最大值-->
<property name="maxActive" value="2" />
<!--最大空闲值-->
<property name="maxIdle" value="1" />
<!--最小空闲值-->
<property name="minIdle" value="1" />
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">
true
</prop>
</props>
</property>
<property name="packagesToScan" value="main.java.com.lkt.system.bean"></property>
</bean>
</beans>
2、接口

package main.java.com.lkt.dao;

import java.io.Serializable;
import java.util.List;

public interface CommDao<T> {

/**
* 获取所有
* @return
*/
public List<T> getAll(T obj);
/**
* 根据Id获取
* @param id
* @return
*/
public T getById(Serializable id);
/**
* 根据名称获取
* @param name
* @return
*/
public T getByName(String name);
/**
* 删除
* @param obj
* @return
*/
public Serializable del(T obj);
/**
* 添加
* @param obj
* @return
*/
public Serializable add(T obj);
/**
* 修改
* @param obj
* @return
*/
public Serializable update(T obj);
/**
* 批量添加
* @param objList
* @return
*/
public Serializable addBatch(final List<T> objList);
}

3、实现，继承HibernateDaoSupport，注入sessionFactory，使用getHibernateTemplate()获取Hibernate模板
package main.java.com.lkt.dao;

import java.io.Serializable;
import java.util.List;
import java.util.Map;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
@Repository("hibernateDaoImpl")
public class HibernateDaoImpl<T> extends HibernateDaoSupport implements CommDao<T> {

@Resource(name="sessionFactory")
public void setSuperSessionFactory(SessionFactory sessionFactory){
super.setSessionFactory(sessionFactory);
}

@Override
public List<T> getByHql(String hql, Object... param) {

return null;
}

@Override
public List<T> getAll(T obj) {
// TODO Auto-generated method stub
return null;
}

@Override
public T getById(Serializable id) {
// TODO Auto-generated method stub
return null;
}

@Override
public T getByName(String name) {
// TODO Auto-generated method stub
return null;
}

@Override
public Serializable del(T obj) {
// TODO Auto-generated method stub
return null;
}

@Override
public Serializable add(T obj) {
return getHibernateTemplate().save(obj);
}

@Override
public Serializable update(T obj) {
// TODO Auto-generated method stub
return null;
}

@Override
public Serializable addBatch(List<T> objList) {
// TODO Auto-generated method stub
return null;
}

}
