1、配置数据源

<?xml version="1.0" encoding="UTF-8"?><beansxmlns="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.xsdhttp://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&amp;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);}@Overridepublic List<T> getByHql(String hql, Object... param) {return null;}@Overridepublic List<T> getAll(T obj) {// TODO Auto-generated method stubreturn null;}@Overridepublic T getById(Serializable id) {// TODO Auto-generated method stubreturn null;}@Overridepublic T getByName(String name) {// TODO Auto-generated method stubreturn null;}@Overridepublic Serializable del(T obj) {// TODO Auto-generated method stubreturn null;}@Overridepublic Serializable add(T obj) {return getHibernateTemplate().save(obj);}@Overridepublic Serializable update(T obj) {// TODO Auto-generated method stubreturn null;}@Overridepublic Serializable addBatch(List<T> objList) {// TODO Auto-generated method stubreturn null;}}
