春季休眠配置默認使用resource_local或jta？

Question

我知道我的配置是直接在applicationContext.xml上完成的，我沒有persistence.xml。默認情況下這是resource_loca或jta？如果我想使用jta，是否需要添加額外的參數？

<bean id="dataSource" 
     class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
     <property name="driverClassName"> 
      <value>oracle.jdbc.driver.OracleDriver</value> 
     </property> 
      <!-- xdb is defined by running the hsqldb as xdb (see above) --> 
     <property name="url"> 
      <value>jdbc:oracle:thin:@theserver:1521:appsdb</value> 
     </property> 
     <property name="username"> 
      <value>test</value> 
     </property> 
     <property name="password"> 
      <value>test</value> 
     </property> 
    </bean> 




<bean id="annotatedsessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 


    <property name="packagesToScan" value="com.company.x.model" > 
    </property> 


    <property name="hibernateProperties"> 
     <props> 

      <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> 
      <prop key="hibernate.show_sql">true</prop>

      <prop key="hibernate.c3p0.timeout">1800</prop> 
      <prop key="hibernate.c3p0.max_statements">50</prop> 
      <prop key="hibernate.cache.provider_class">

      <prop key="hibernate.cache.use_second_level_cache">true</prop> 
      <prop key="hibernate.cache.use_query_cache">true</prop> 



     </props> 
    </property> 
    <property name="dataSource"> 
     <ref bean="dataSource" /> 
    </property> 

</bean>

RESOURCE_LOCAL僅適用於JPA EntityManager，而不是一個Hibernate SessionFactory。 Hibernate的Spring集成比JPA更平滑，因此決定事務行爲的唯一因素是您使用哪個事務管理器（HibernateTransactionManager或JtaTransactionManager）。它可以與任何一個協同工作，而無需明確配置SessionFactory。
