Question

I have a Spring MVC application using JPA 2. All the controllers are annotated with @Transactional at the class level.

Is it possible to keep that annotation at the class level and simply override it with another @Transactional annotation at the method level? I have one method I’d like to make SERIALIZABLE.

Answer 1

You can add multiple transaction managers by adding qualifiers to distinguish which one that should be used, provided that they have been configured:

@Transactional("global")
public class SomeService {

    public void methodThatUsesTheGlobalTxManager() {
        // ...
    }

    @Transactional("special")
    public void methodThatUsesTheSpecialTxManager() {
        // ...
    }        
}
