Handle mongodb connection issues on startup

autowired

startup

I've integrated MongoDB using Spring, my data service has a mongo repository autowired, and it all works. Except when the db is down during startup.

When mongo is down while the service comes up, there's an exception thrown during initialization, and in that case the whole service fails to start up. This is not what I want obviously.

What I would like to happen is to catch the exception and start the service, and handle the db availability problem gracefully (like show a page saying we've got temporary problems, use a cache, or whatever)

My repository class:

public interface MediaDataRepository extends MongoRepository<MediaData, String> {
...
}

My service class:

@Service
public class MediaDataService {
    @Autowired
    private MediaDataRepository mediaDataRepository;
...
}

And Controller:

@Controller
@RequestMapping("/api/consumer")
public class MediaController extends HtmlGenerationController {
    private static final Logger LOG = LoggerFactory.getLogger(MediaController.class);

    @Autowired
    private MediaDataService mediaDataService;
...
}

The error I get during startup:

2013-01-15 17:50:09.163:WARN:oejw.WebAppContext:Failed startup of context o.m.j.p.JettyWebAppContext{/,file:/code/src/main/webapp/},file:/code/src/main/webapp/

Why is my MongoDB not connecting?

Ensure that your MongoDB instance is running: Compass must connect to a running MongoDB instance. Also check you have installed MongoDB and have a running mongod process. You should also check that the port where MongoDB is running matches the port you provide in the compass connect.

Can't connect to server connection refused MongoDB?

Normally this caused because you didn't start mongod process before you try starting mongo shell. This case worked out for me, i had to do ~>sudo mongod --dbpath /dbpathlocation and then opened the new terminal to run mongo...

In my searches, I found no good way to make Spring handle this directly. You likely need to put a proxy between your service and the repository. A post here: How to make App server to start even if database is down? approaches this issue.

For you, this probably means having a bean (RepositoryProxy) which Spring creates. This bean will try to create the Mongo connection manually, or get the repository from the application context's lazy bean. If the Mongo connection fails, it catches the exception and creates a connection/object for cached data or error responses. It may also create a timer process to reconnect to the Mongo instance.
