How, depending on the settings in the property file, force service to use a particular repository?

I set VM options to -Dmyapp.conf=config/my.properties. I need to use this file content to select which repository to use. I use SpringBoot.

There is service, now it gives Could not autowire. There is more than one bean of 'MyRepository' type:

@Service
public class MyServiceImpl implements MyService {

    @Autowired
    private MyRepository repository;
...}

Repositories:

public interface MyRepository  {...}

@Repository
public class MyRepositoryImpl01 implements MyRepository  {...}

@Repository
public class MyRepositoryImpl02 implements MyRepository  {...}

I would actually consider having this logic in some Java Config (a class annotated with @Configurtation) than in both (or possibly N) repositories.

You could use @ConditionalOnProperty and in this Java Config you would encapsulate entire logic of this "repository selection". This would be a benefit since you would only have 1 bean of the specified type, which in turn could be useful if your repositories connect to databases that are not available for certain configuration options.

You can use Spring profiles for that purpose.

@Profile("profile1")
@Repository
public class MyRepositoryImpl01 implements MyRepository  {...}

@Profile("profile2")
@Repository
public class MyRepositoryImpl02 implements MyRepository  {...}

Then in the property file you need: spring.profiles.active=profile1 or spring.profiles.active=profile2.
