本文介绍如何使用Spring的AnnotationSessionFactoryBean来集成Hibernate，并利用JDK 1.5+的注解元数据进行映射。提供了具体的配置示例，包括通过指定数据源、扫描指定包内的实体类等。

1：

public class AnnotationSessionFactoryBeanextends LocalSessionFactoryBean

Subclass of Spring's standard LocalSessionFactoryBean for Hibernate3, supporting JDK 1.5+ annotation metadata for mappings. Requires the Hibernate3 Annotation add-on to be present.

2：实例代码

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
   <property name="dataSource">
     <ref bean="dataSource"/>
   </property>
   <property name="annotatedClasses">
     <list>
       <value>test.package.Foo</value>
       <value>test.package.Bar</value>
     </list>
   </property>
   <property name="annotatedPackages">
     <list>
       <value>test.package</value>
     </list>
   </property>
 </bean>

3:实际运用

图：User类

其中类应用了Hibernate和Spring的注解

图：应用中的配置信息

补充：官方文档给出的示例http://static.springsource.org/spring/docs/2.5.6/api/org /springframework/orm/hibernate3/annotation/AnnotationSessionFactoryBean.html

org.springframework.orm.hibernate3.annotation
Class AnnotationSessionFactoryBean

java.lang.Object

extended by

org.springframework.orm.hibernate3.AbstractSessionFactoryBean

extended by

org.springframework.orm.hibernate3.LocalSessionFactoryBean

extended by

org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean

All Implemented Interfaces:

BeanClassLoaderAware, DisposableBean, FactoryBean, InitializingBean, ResourceLoaderAware, PersistenceExceptionTranslator

public class AnnotationSessionFactoryBeanextends LocalSessionFactoryBeanimplements ResourceLoaderAware

Subclass of Spring's standard LocalSessionFactoryBean for Hibernate, supporting JDK 1.5+ annotation metadata for mappings.

Note: This class requires Hibernate 3.2 or higher, with the Java Persistence API and the Hibernate Annotations add-on present.

Example for an AnnotationSessionFactoryBean bean definition:

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
   <property name="dataSource" ref="dataSource"/>
   <property name="annotatedClasses">
     <list>
       <value>test.package.Foo</value>
       <value>test.package.Bar</value>
     </list>
   </property>
 </bean>

Or when using classpath scanning for autodetection of entity classes:

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
   <property name="dataSource" ref="dataSource"/>
   <property name="packagesToScan" value="test.package"/>
 </bean>

Since:

1.2.2
