spring.jar
hibernate3.jar
dom4j-1.6.1.jar

以下为其配置文件：

==========service.xml===============

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean id="productService" class="com.me.service.ProductService">
<property name="productDao">
<ref bean="productDao" />
</property>
</bean>
....
当然还有product.hbm.xml，如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--
- Mapping file for the Hibernate implementation of the Clinic interface.
-->
<hibernate-mapping auto-import="true" default-lazy="false">
<class name="com.me.domain.Product" table="product">
<id name="productId" column="productId">
<generator class="assigned" />
</id>
<property name="name" column="name" />
<property name="category" column="category" />
<property name="description" column="descn" />
</class>
</hibernate-mapping>
==== Product 文件如下：=======
public class Product implements Serializable {
/* Private Fields */
private String productId;
private String categoryId;
private String name;
private String description;
private String category;
....setter/getter方法
=================测试如下=========
public class HibernateDBTest {
/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "services.xml", "hibernate-daos.xml" });
ProductService productService = (ProductService) context
.getBean("productService");
String productId="AV-CB-01";
Product product=productService.getProductByID(productId);
System.out.println(product);
}
}
测试结果OK。
