To properly support general post processing of query execution results (in QueryExecutorMethodInterceptor) we need to remove the eager post-processing of query execution results in AbstractMongoQuery.
Removed the usage of the local ConversionService all together.
We now handle intercepted finalize method invocations by not resolving the proxy. Previously the LazyLoadingProxy tried to resolve the proxy during finalization which could lead to unnecessary database accesses.

We changed the id resolution to skip properties having an explicit name set via @Field unless they are marked with @Id. This means that
@Field(“id”) String id;
will be stored as “id” within mongodb. Prior to this change the fieldname would have been changed to “_id”.
Added tests to ensure proper field mapping for various "id" field variants.

The QueryMapping for derived repository queries pointing to the identifier of the referenced document. We now reduce the query field's key from reference.id to reference so that the generated DBRef is applied correctly and also take care that the id's are potentially converted to ObjectIds. This is mainly achieved by using the AssociationConverter pulled up from UpdateMapper in ObjectMapper.getMappedKey().
MongoQueryCreator now refrains from translating the field keys as that will fail the QueryMapper to correctly detect id properties.
Fixed DBRef handling for StringBasedMongoQuery which previously didn't parse the DBRef instance created after JSON parsing for placeholders.
We now only perform a type check on via @Language explicitly defined language properties. Prior to this change non-String properties named language caused errors on entity validation.

Slightly tweaked the changes in SlicedExecution to simplify the implementation. We now apply the given pageable but tweak the limit the query uses to peek into the next page.
Original pull request: #226.
We now directly set the offset to use instead of reading it from the used pageable. This asserts that every single element is read from the store.
Prior to this change the altered pageSize lead to an unintended increase of the number of elements to skip.
Original pull request: #226.
We now use property.getFieldName() for mapping DbRefs. This assures we also capture explicitly defined names set via @Field.

The test rejectsAddressConfigWithoutASingleParsableServerAddress fails because the supposedly non-existing hostname "bar" "now" resolves to a real host-address.
The addresses "gugu.nonexistant.example.org, gaga.nonexistant.example.org" shouldn't be resolvable TM.
Original pull request: #229.
We now check for an explicitly declared language field for setting language_override within a text index. Therefore the attribute (even if named with the reserved keyword language) has to be explicitly marked with @Language. Prior to this change having:
@Language String lang;
String language;
would have caused trouble when trying to resolve index structures as one cannot set language override to more than one property.
Original pull request: #224.
Improved the exception message that is occurs if the source document contains a BasicDBList but has to be converted into a complex object. We now explicitly hint to use a custom Converter to manually.
Improved toString() method on ObjectPath to create more helpful output.
We new prefix explicitly named indexes on nested types (eg. for embedded properties) with the path pointing to the property. This avoids errors having equally named index definitions on different paths pointing to the same type within one collection.
Along the way we harmonized index naming for geospatial index definitions where only the properties field name was taken into account where it should have been the full property path.

Using Meta allows to the define $comment, $maxScan, $maxTimeMS and $snapshot on query. When executed we add the meta information to the cursor in use.
We’ve introduced the @Meta annotation that allows to the define $comment, $maxScan, $maxTimeMS and $snapshot on a repository finder method.
Added tests to verify proper invocation of template methods
Use DBCursor.copy() for CursorPreparer.

Identifier initalization is now only triggered if field access is used. Before that the id initialization would've resolved the proxy eagerly as the getter access performed by the BeanWrapper would've been intercepted by the proxy and is indistinguishable from a normal method call. This would've rendered the entire use case to create proxies ad absurdum.
Added test case to check for non-initialization in the property access scenario.
We now initialize the ID property for proxies created for lazily initialized DBRefs. This will allow the lookup of ID properties for types that use field access without initializing the entire proxy.
Simplified implementation of ObjectPath to use a static root instance and hand the path further down until final resolution in MappingMongoConverter.readValue(…). This removes a bit of boxing and unboxing code both in ObjectPath and the converter.
Introduced ObjectPath.getPathItem(…) to internalize the iteration to find a potentially already resolved object.
Renamed parameters and fields of type ObjectPath to path consistently. Removed obsolete method in MappingMongoConverter.
Original pull request: #209.
Introduced ObjectPath that collects the target objects while converting a DBObject to a domain object. If we detect that a potentially nested DBRef points to an object that is already under construction we simply return a reference to that object in order to avoid StackOverFlowErrors.

Added support to execute full-text queries on repositories. Query methods now can have a parameter of type TextCriteria which will be triggering a text search clause for the property annotated with @TestScore.
Retrieving document score and sorting by score is only possible if the entity holds a property annotated with @TextScore. If present, any find execution will be enriched so that it asserts loading of the according { $meta : textScore } field. The sort object will only be mapped in case the existing sort property already exists - in that case we replace the existing expression for the property with its $meta representation.
This allows for example the following:
TextCriteria criteria = TextCriteria.forDefaultLanguage().matching("term");
repository.findAllBy(criteria, new Sort("score"));
repository.findAllBy(criteria, new PageRequest(0, 10, Direction.DESC, "score"));
repository.findByFooOrderByScoreDesc("foo", criteria);
For more details and examples see the "Full text search queries" section in the reference manual.
We now resolve the target type for CGLib-proxied objects and initialize lazy loaded ones before saving. As it turns out CustomConversions already knows how to deal with proxies correctly. Ee added an explicit test to assert that.
Original pull request: #208.
A simple call of toString() on a DBObject might result in an exception if the DBObject contains objects that are non-native MongoDB types (i.e. types that need to be converted prior to persistence).
We now use SerializationUtils.serializeToJsonSafely(…) to avoid exceptions.
Introduced ParameterBindingParser which exposes parameter references in query strings as ParameterBindings. This allows us to detect whether a parameter reference in a query string is already quoted avoiding wrongly double-quoting the parameter value.
Original pull request: #185.

The fix for DATAMONGO-950 introduced a tiny glitch so that retrieving pages after the first one was broken in the repository query execution. We now correctly use the previously detected number of elements to detect whether the Pageable given is out of scope.
