Prevent Mongo indexing

[h2cl]

Hi there.

I'm using Spring Datastore Document and MongoDB. My Problem is that I can't (should) change the indexing of mongo but for every event defined in my extended MongoRepository (like findBySomething(String some)) an index is created. So I can't use it. Is there a way to prevent creating the index by spring-data-mongodb?

MongoRepositoryFactoryBean currently adds the IndexEnsuringQueryCreationListener inside createRepositoryFactory(). So you could easily create a sub-class of the FactoryBean override the method and then let the namespace work with your repository class (see the factory-class attribute in the namespace).

We definitely should make this more convenient by being able to switch that of with a simple flag at the namespace. Feel free to open a JIRA ticket for this.

I can't overwrite it, cause it requires access to private variable template:

public class MyMongoRepositoryFactoryBean<T extends Repository<S, ID>, S, ID extends Serializable> extends MongoRepositoryFactoryBean<T, S, ID> {
    @Override
    protected RepositoryFactorySupport createRepositoryFactory() {
        MongoRepositoryFactory factory = new MongoRepositoryFactory(template);
        return factory;
    }
}

You could try overriding the setter for the template and shadow the field. Admittedly this way the hack even becomes an ugly hack . I've created a ticket to add the flag to disable repository method index creation [0], as well as one to improve extensibility of MongoRepositoryFactoryBean [1].
