Hi,
I've been reading quite a lot of documentation around named bindings,
factorymodulebuilder, mapped bindings and it is still not clear if I can
achieve something along the following lines.
For example I want a Factory to be able to look up different services at
runtime based a key. In spring you can do something like this
public class ServiceFactory {
private Map<String, Service> services = new HashMap<String, Service>();
@Autowired
private Map<String, Service> mappedServices;
public void init() {
services.put(SitemapListService.class.getName(), new
SitemapListService());
services.put(SitemapService.class.getName(), new
SitemapService());
services.put(SitemapExcelService.class.getName(), new
SitemapExcelService());
services.put(CategoryService.class.getName(), new
CategoryService());
services.put(AdminDirectoryListService.class.getName(), new
AdminDirectoryListService());
services.put(CompositeConceptsService.class.getName(), new
CompositeConceptsService());
}
public Service getService(String key) {
Service service = services.get(key);
if (service == null) {
throw new IllegalArgumentException("Unknown service
type: " + key);
}
return service;
}
}
Then for example the service name could be configured in a configuration file
or calculated at runtime? How can I achieve something similar with Guice?
Thanks
Jon
