Version 1.2.0 of bson4jackson has just been released. bson4jackson adds support for BSON, a binary representation of JSON, to the Jackson JSON processor. Thanks to contributions from the community, the latest release of bson4jackson now includes better support for MongoDB.
Gergő Ertli has fixed the support for the
ObjectId type. Object IDs are used as the primary key for MongoDB documents.
Support for the
UUID type has been added by Ed Anuff. He added a new module which can be registered to Jackson’s
ObjectMapper om = new ObjectMapper(new BsonFactory()); om.registerModule(new BsonUuidModule());
Thanks to the contribution by James Roper the
BsonParser class now supports the new
HONOR_DOCUMENT_LENGTH feature which makes the parser honor the first 4 bytes of a document which usually contain the document’s size. Of course, this only works if
BsonGenerator.Feature.ENABLE_STREAMING has not been enabled during document generation.
This feature can be useful for reading consecutive documents from an input stream produced by MongoDB. You can enable it as follows:
BsonFactory fac = new BsonFactory(); fac.enable(BsonParser.Feature.HONOR_DOCUMENT_LENGTH); BsonParser parser = (BsonParser)fac.createJsonParser(...);
Apart from that, a lot of other minor bugs have been fixed. The library has been tested with Jackson 1.7 up to 1.9.
