spring multiple transactionmanagers for similar datasources

I have two datasources that are equal in their structure but not in their Data. My application has to deal with both of them at the same time. I have controller, servie, dao structure that looks like this.

Controller Modell:

@Controller
public abstract class MyFancyControllerModell{
    private MyService service;

    public MyFancyControllerModell (MyService service){
        this.service = service;
    }

    @RequestMapping(....)
    public void editSomeData(String data){....}
}

Controller implementation:

@Controller
@RequestMapping(...)
public class MyControllerImpl1 extends MyFancyControllerModell{
    @Autowired
    public MyControllerImpl1(@Qualifier("myServiceInstance1") MyService service){
        super(service);
    }
}

@Controller
@RequestMapping(...)
public class MyControllerImpl2 extends MyFancyControllerModell{
    @Autowired
    public MyControllerImpl2(@Qualifier("myServiceInstance2") MyService service){
        super(service);
    }
}

And the Service:

public class MyService{
    private MyDao myDao;

    public MyService(MyDao myDao){
        this.myDao = myDao;
    }

    @Transactional
    public void editSomeData(String data){...}
}

I create the Beans in my configuration class like this:

private DataSource lookupDataSource(final String jndiName) {
  final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
  dsLookup.setResourceRef(true);
  return dsLookup.getDataSource(jndiName);
}

@Bean
public DataSource dataSource1(){
    return lookUpDataSource("dataSource1");
}

@Bean
public DataSource dataSource2(){
    return lookUpDataSource("dataSource2");
}

@Bean
public MyService myServiceInstance1(@Qualifier("dataSource1") DataSource dataSource){
    return new(MyService(new MyDao(dataSource))));
}

@Bean
public MyService myServiceInstance1(@Qualifier("dataSource1") DataSource dataSource){
    return new(MyService(new MyDao(dataSource)));
}

My question is, is it possible to create transactionmanagers for both datasources without the need to declare in the service layer which transactionmanager is used?

I tried creating them as bean just like the services but that did not work.
