Using KMongo for mongo serialization framework

MIGHT NOT SUPPORT JAVA 1.7!
Benefits :

Works with data classes without empty ctor
No need to use iterators (they are all abstracted away, no need to use BasicDBObjects)
Type safe queries
They're all extension functions, so you can fallback to your java ways if you want

How to ?

add compile 'org.litote.kmongo:kmongo:3.8.2' to build.gradle
see following snippet to register the a jackson serialization codec for mongo bson

class SomeMongoAccessor(mongoDatabase: MongoDatabase)
: SomeAccessor {
private val codecRegistry = ClassMappingType
.codecRegistry(MongoClient.getDefaultCodecRegistry())
private val collection = mongoDatabase
.getCollection("your.collection", YourDataClass::class.java)
.withCodecRegistry(codecRegistry)
}

3. Done! you can code such as
collection.insertOne(YourDataClass(_id = id))
or,

return  collection
.find(filters)
.sort(descending(AccomPropertyMergeTaskHistory::_id))
.limit(limit+1)
.toMutableList()

collection.updateOne(
and(
AccomPropertyMergeTask::_id eq id,
or(
AccomPropertyMergeTask::resolution eq Free,
AccomPropertyMergeTask::resolution eq Locked,
AccomPropertyMergeTask::resolution eq Archive
)
),
set(
AccomPropertyMergeTask::handledTime setTo currentTime,
AccomPropertyMergeTask::resolution setTo resolution.toString(),
AccomPropertyMergeTask::handledBy setTo handledBy
)

Note: this doesn't automatically add __lut field!
