Introduced usePropertyAccess() method on MongoPersistentProperty and added an implementation that forces that into being true for Throwable.cause as using the field would cause a cycle as it points to this in the first place but rather massages the value in the getter.
Added some code to MongoTemplate that inspects the object to be saved for being a String. If it is we try to parse the given String into a JSON document and continue as if we had been given a DBObject initially. Non-parseable Strings are rejected with a MappingException.
Guarded access to results of mappingContext.getPersistentEntity(…) to prevent NullPointerExceptions in case the template is used with non-entity types like a plain DBObject. Added some custom logic for plain BasicDBObjects to get the _id field populated appropriately.
Updated dependency versions to Spring Data MongoDB and Spring. Removed explicit dependency listing. Removed section on how to migrate between 1.0 milestones. Removed obsolete paragraphs.
If the entity being removed using MongoTemplate.remove(object, collectionName) contained an id that could be converted into an ObjectID it wasn't removed correctly currently. This was caused by the fact that the intermediate call didn't hand over the entity type and thus the id conversion failed. This in turn caused the query not to match the previous saved object.
Introduced with(Sort sort) and with(Pageable pageable) on Query. Deprecated sort() method and the custom Sort class. Deprecated QueryUtils.applyPagination(…) and ….applySorting(…) and changed internal calls to this to use the Query API directly. Some JavaDoc polishing.
In multithreaded environments Mongo database authentication can be triggered twice if two or more threads refer to the same db instance. This is now prevented by synchronizing calls to db.authenticate(…).
We now make sure we really re-use the database instance bound to the thread avoiding duplicate lookups of Mongo.getDb(…). This doesn't seem to gain a big performance benefit anymore as the Mongo instance caches the DB instances internally anyway.
Introduced @Version annotation to demarcate a version property on an entity. MongoTemplate will initialize this property on the first save of an instance if not set already. If it is already set, the template will bump the version number on subsequent saves and actually trigger an update backed by a query including the old version number. A failure to update the entity accordingly will then trigger an OptimisticLockingFailureException.
General JavaDoc polish in mapping package.
In cases an ApplicationContext already contains a MongoPersistentEntityIndexCreator the default one is not registered, even if the one in the ApplicationContext listens to another MappingContext's events.
Polished iterable classes setup in MongoTemplate along the way. Some JavaDoc polishes as well.
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.
