我在基于注释的配置类中配置了两个事务管理器:
@Configuration
@EnableTransactionManagement
public class DBConfig implements TransactionManagementConfigurer {
//...
@Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return defTransactionManager();
}
@Bean
@Qualifier("defSessionFactory")
public LocalSessionFactoryBean defSessionFactory() {
LocalSessionFactoryBean sfb = new LocalSessionFactoryBean();
sfb.setDataSource(defDataSource());
Properties props = new Properties();
//...
sfb.setHibernateProperties(props);
sfb.setPackagesToScan("my.package");
return sfb;
}
@Bean
@Qualifier("defTransactionManager")
public PlatformTransactionManager defTransactionManager() {
return new HibernateTransactionManager(defSessionFactory().getObject());
}
@Bean
@Qualifier("secondSessionFactory")
public LocalSessionFactoryBean secondSessionFactory() {
LocalSessionFactoryBean sfb = new LocalSessionFactoryBean();
sfb.setDataSource(secondDataSource());
Properties props = new Properties();
//...
sfb.setHibernateProperties(props);
sfb.setPackagesToScan("my.package.subpackage");
return sfb;
}
@Bean
@Qualifier("secondTM")
public PlatformTransactionManager secondTransactionManager() {
return new HibernateTransactionManager(secondSessionFactory().getObject());
}
}
我的意图是使用两个事务管理器的注释事务.
Methonds注释如下
@Transactional
public void method() {}
应该由defTransactionManager处理
并且方法注释如下
@Transactional("secondTM")
public void anotherMethod() {}
通过secondTransactionManager
defTransactionManager工作正常但是当涉及到anotherMethod()时,我得到:
org.hibernate.HibernateException: No Session found for current thread
当我对anotherMethod使用程序化事务管理(autowire secondSessionFactory,使用TransactionTemplate)时,一切正常.
最佳答案 如果
@EnableTranscationManagement Spring将使用按类型查找,您可以为单个事务管理器提供自己的查找方法,但是
it will not work for two tx managers
如果要检查Spring如何确定要执行的事务,可以尝试调试TransactionAspectSupport类.关键方法是setTransactionManagerBeanName和determineTransactionManager.
