Issue
What I have done currently is
Created an abstract class
public interface AbstractRawPathStrategy {
String getRouteKey();
void processRequest();
}
Implemented the classes
public class GetDocumentImpl implements AbstractRawPathStrategy {
@Override
public String getRouteKey() {
return "GET_DOCUMENT";
}
@Override
public void processRequest() {
log.info("Inside get document");
}
}
Created a routing factory
public class RawPathStrategyFactory {
private final Map<String, AbstractRawPathStrategy> dictionary;
@Inject
public RawPathStrategyFactory(final Set<AbstractRawPathStrategy> abstractRawPathStrategySet) {
dictionary = new HashMap<>();
for (AbstractRawPathStrategy abstractRawPathStrategy : abstractRawPathStrategySet) {
dictionary.put(abstractRawPathStrategy.getRouteKey(), abstractRawPathStrategy);
}
}
public AbstractRawPathStrategy getByRouteKey(final String rawPath) {
return dictionary.get(rawPath);
}
}
Instantiated the factory
@Module
public class AppModule {
@Provides
@Singleton
public RawPathStrategyFactory getRouteKeyStrategyFactory() {
Set<AbstractRawPathStrategy> abstractRouteKeyStrategies = new HashSet<>();
abstractRouteKeyStrategies.add(new GetDocumentImpl());
abstractRouteKeyStrategies.add(new GetUserRightsImpl());
return new RawPathStrategyFactory(abstractRouteKeyStrategies);
}
What I want is to go to respective class based on the route key (String). How can this be done without instantiating each class with new in AppModule. Any cleaner way to do this?
Solution
Try to use multibindings when create RawPathStrategyFactory https://dagger.dev/dev-guide/multibindings.html
