在@Configuration类中设置Spring中的注释驱动事务

Question

So in the latest version of Spring we are able to use the @Configuration annotation to setup our configurations for Spring. Now in JavaConfig it is possible to use the @AnnotationDrivenTx ( @AnnotationDrivenTx Reference Link) annotation to setup transactions in our Config class. But since JavaConfig has been decommissioned I was wondering if anyone knew how to setup something similar without JavaConfig and without needing to add anything to the application-context.xml . Here is what I basically have for my Config class

@Configuration
@ImportResource("config/application-context.xml")
public class Config {

     public @Bean DataSource dataSource() {
           //get and return datasource
     }

     public @Bean Service1 getService1() {
          //return service1Impl
     }
}

And I'd like to make Service1 transactional. If anyone has any ideas on how to do this or if this is just not possible please let me know.

Thanks!

Answer 1

You can now use @EnableTransactionManagement .

Answer 2

It seems like it isn't possible according to this forum post :

there may be a more first-class mechanism for enabling annotation-driven TX in @Configuration classes in Spring 3.1, but in the meantime, the recommended approach is to use @ImportResource to include a snippet of XML that declares <tx:annotation-driven/>

Wait: but you seem to have an XML context anyway. Why not add <tx:annotation-driven/> to it and use @Transactional ?

Take a look at http://blog.springsource.com/2011/02/17/spring-3-1-m1-featurespec . Spring 3.1's FeatureSpecification classes such as TxAnnotationDriven are designed to solve exactly the problem described above.
