MongoDB - Non-primitive options

Hi,

I'd like to be able to provide my own SocketFactory for MongoClient to use which is usually possible by passing it to MongoClientOptions.Builder. OGM currently allows MongoClientOptions to be configured via properties with the prefix 'hibernate.ogm.mongodb.driver.' which are then set in the options builder via reflection in MongoDBConfiguration.buildOptions. My problem is that the method which builds the list of options setting methods (createSettingsMap) currently excludes all non-primitive options. I was wondering whether this restriction could potentially be lifted or if there were any alternative ways to make it use a specific instance of SocketFactory?

Thanks,
David.

Hi,
I've created a new JIRA for it: https://hibernate.atlassian.net/browse/OGM-975

We'll try to fix as soon as possible.
If you want to speed up the process you could try to create a fix for it; the jira contains some explanations and a patch with a test case.

As a temporary workaround you can ovverride MongoDBDatastoreProvider to create your MongoClient.

Thanks for the feedback,
Davide

Thanks Davide. We can work around this for the moment but eventually we'll need this functionality so we'll pick up the ticket at that time unless someone else gets to it first.

Thanks,
David.

Hey David,

Can you tell us why you need to pass your own SocketFactory ? Looks at first sight like an unfrequent requirement so that's interesting to hear your needs.

Hi Emmanuel,

Our application needs to communicate with MongoDB over SSL. We're planning on deploying in Docker containers and I want our images to be non-environment specific so would like the ability to provide a reference to the SSL certificates when the container is started and for the application to programmatically retrieve the certificates and install them in a trust store. In order to use these certificates for connecting to MongoDB we'd need to use an instance of an SSLSocketFactory which used this specific trust store rather than the default one.

Thanks, interesting.

DavidW_asdf, it should be possible to lift that restriction, but naturally this would not work when configuring Hibernate OGM through persistence.xml, hibernate.properties and the like. I.e. you'd have to bootstrap Hibernate OGM programmatically in order to pass in an actual instance of the socket factory. Out of curiousity, how are you bootstrapping it atm.?

Thanks,

Hi Gunnar,

We have persistence.xml files for non-environment specific settings (entities, transaction types etc) and then we bootstrap in Guice/Onami Persistence where we programmatically supplement those properties with the environment specific ones. e.g.

Code:

  protected Properties mongoDbJpaConfigurationFrom(final String dbUriProperty) {
    final MongoDbConfig config = MongoDbConfig.fromURI(getProperty(dbUriProperty));
    Properties properties = new Properties();
    properties.put("hibernate.ogm.datastore.database", config.getDatabase());
    properties.put("hibernate.ogm.datastore.host", config.toHostAddress());
    properties.put("hibernate.ogm.datastore.username", config.getUsername());
    properties.put("hibernate.ogm.datastore.password", config.getPassword());
    properties.put("org.hibernate.flushMode", "COMMIT");

    if(config.isSsl()) {
      properties.put("hibernate.ogm.mongodb.driver.sslEnabled", true);
      properties.put("hibernate.ogm.mongodb.driver.sslInvalidHostNameAllowed", true);
      // TODO: add certificate import
    }

    return properties;
  }

Thanks,
Dave.

Thanks for the reply, Dave; Then we should be able to get this working.

Note there is OgmProperties which defines constants for most of the properties, so you don't need to write out those as Strings.
