Update README to remove references to old API, Docs links as well as CouchDB. Remove reference to Spring Data Document, copy initial paragraph introducing the project from http://www.springsource.org/spring-data/mongodb
Introduced intermediate getMappedKeyword(Keyword keyword, MongoPersistentProperty property) to correctly return a DBObject for keyword plus converted value. A few refactorings and improvements in the implementation of QueryMapper (Keyword value object etc.).
We move away from Maven version ranges as they complicate the build and dependency resolution process. They make the build in-reproducible. Users stuck with a 3.0.x version of Spring will now have to manually declare Spring dependencies in their needed 3.0.x version. Not that at least Spring 3.0.7 is required currently.
Index creation now double checks the MappingContext a MappingContextEvent originates from before actually creating indexes. This avoids invalid indexes being created in a multi-database scenario.
AbstractMappingConfiguration now uses the package of the class extending it to enable entity scanning for that package. To disable entity scanning entirely override the method to return null or an empty String.
Reading an empty collection always returned a HashSet assuming the returned value would be converted into the assigned properties value later on. However the method should rather return the correct type already which we do now by invoking the potential conversion.
$ne expressions are now only being tried to be converted into an ObjectId in case they follow an id property. Previously they tried in every case which might have led to Strings being converted into ObjectIds that accidentally were valid ObjectIds but didn't represent an id at all.
So far the algorithm to inspect whether an id property has to be set after a save(…) operation has used the plain BeanWrapper.getProperty(PersistentProperty property) method. This caused problems in case the getter of the id field returned something completely different (to be precise: a complex type not convertible out of the box).
We now inspect the id field only to retrieve the value.
When reading BasicDBLists we now make sure the resulting collection is converted into the actual target type eventually. It might be an array and thus need an additional round of massaging before being returned as value.
As we try to massage the value of the id property into an ObjectId if possible we need to do so as well when mapping the Querydsl query. Adapted SpringDataMongoDbSerializer accordingly.
MongoDbUtils now correctly returns DB instances for others than the first one bound. So far the lookup for an alternate database resulted in the first one bound to be returned. Polished log statements a bit.
