Polished pom.xml files. Upgraded to Log4J 1.2.16 as it excludes unnecessary dependencies. Consolidated test dependencies into parent pom. Remove dependency-management sections. Exclude commons-logging in favor of SLF4J.
If you have a property of type object and it contains a collection we didn't property read it back in as creating the collection instance failed due to an invalid call to CollectionFactory. We now default the parameter handed to that call to List in case the property type is not a Collection at all.
We now provide a GridFsTemplate for storing, retrieving and deleting documents from GridFS. Introduced GridFsResource implementation to integrate with Spring's Resource abstraction. Beyond that GridFsOperations extends ResourcePatternResolver and thus allows to retrieve GridFsResources via Ant-style filename patterns.
Huge refactoring of the way MappingMongoConverter instantiates entities. The constructor arguments now have to mirror a property exactly in terms of name. Thus we can pick up mapping information from the property to lookup the correct value from the source document. The @Value annotation can be used to either inject completely arbitrary values into the instance (e.g. by referring to a Spring bean) or simply define an expression against DBObject's fields:
class Sample {
String foo;
String bar;
Sample(String foo, @Value("#root._bar") String bar) {
this.foo = foo;
this.bar = bar;
}
}
trying to create an instance of this class from
{ "foo" : "FOO" } -> new Sample("FOO", null)
{ "_bar" : "BAR" } -> new Sample(null, "BAR").
QueryMapper assumed finding a BasicBSONList for $(n)or operators. This is generally true if the DBObject was created through our Query abstraction. If you use the MongoDB driver QueryBuilder this will fail. We're now only insisting on an Iterable which fixes the issue.
Updated changelog, changed reference documentation inclusion links to point to SD Commons 1.0.0.RELEASE documentation. Updated dependency information in reference documentation.
Remonde removal of generic ObjectToStringConverter as it doesn't break our converter lookup due to the changed algorithm how to involve Spring Converters in the conversion process.
The execution of MongoTemplate.geoNear(…) potentially caused NullPointerExceptions in case the actual query does not return any results. The wrapping return object returns null for the result list and general statistics which we didn't shield against.
Documented classpath scanning feature of custom converters (DATAMONGO-301). Documented converter disambiguation using @ReadingConverter, @WritingConverter (DATACMNS-113, DATAMONGO-342). Fixed some code formatting on the way.
CustomConversions now evaluates @ReadingConverter / @WritingConverter when adding Converter implementations. See DATACMNS-113 and the appropriate commit for details. Added unit test to verify StringToBigIntegerConverter does not get added as writing converter.
In case a query referencing an entity's id needs massaging before being executed (e.g. Strings that can be ObjectID) the massaging failed in case the query was built using _id already as we did not detect that one being an id reference as we compared it to the entity's id property name. We now also compare against it's field name.
Changed the setter parameters for ServerAddresses to use arrays instead of List. We now register the ServerAddressPropertyEditor to convert a ServerAddress[] and thus don't register a PropertyEditor for List which caused unwanted side effects before.
If an entity is handed into the template to be saved or inserted we now check that the auto-generated ObjectId can actually be applied to the id property after saving the object.
Throwing an exception if an update does not affect any documents doesn't make sense in all cases. Removed throwing an exception by default but made the relevant method (handleAnyWriteResultErrors(…)) protected so that subclasses might override this behavior.
JavaDoc, Formatting. Made dependencies in DefaultIndexOperations final. Reduced dependency to MongoOperations instead of depending on MongoTemplate directly. Added not-null assertion to constructor of DIO.
