Spring + Hibernate Annotation

Hibernate必需要使用Hibernate 3.2.X以上

一般來說用了Spring架構後,會針對Bean撰寫xxx.hbm.xml檔,及在Spring的XML檔撰寫sessionFactory

如果要在Spring搭配使用Hibernate Annotation,可分兩種環境

純綷的Spring,步驟如下:

1.先將hibernate-annotation.jar及ejb-persistence.jar導入專案,這裏須注意的是ejb-persistence.jar檔通常有很多版本,但重點是裏面要javax.persistence.* package,像我就是用ejb-3.0-public-draft-20060118.jar

2.將sessionFactory的類型改為org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean

3.在sessionFactory裏加上欲對應的model清單...

<property name="annotatedClasses">
    <list>
        <value>欲對應的model名稱(包含package,例onlyfun.model.User)</value>
    </list>
</property>

4.建立hibernate.cfg.xml,範例如下:

<!DOCTYPE hibernate-configuration PUBLIC
  "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd "><hibernate-configuration>
 <session-factory>
  <mapping class="欲對應的model名稱(包含package,例onlyfun.model.User)"/>
 </session-factory>

</hibernate-configuration>

透過Hibernate的config,步驟如下:

1.建立Hibernate.cfg.xml文件,範例如下:

<!DOCTYPE hibernate-configuration PUBLIC
  "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd "><hibernate-configuration>
 <session-factory>
  <mapping class="欲對應的model名稱(包含package,例onlyfun.model.User)"/>
 </session-factory>

</hibernate-configuration>

2.改變Spring config文件中的sessionFactory配置:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocations">

<list>
<value>hibernate.cfg.xml文件路徑(如果有個文件則已逗號(,)隔開)</value>
</list>
</property>
<property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration"/>
