com.mongodb.DBObject / BSON serializer for java

Question

Hi anyone knows of a Java library to help serialize/deserialize a com.mongodb.DBObject into a BSON binary and vise-versa?

Have you looked at the MongoDB docs for their class library? api.mongodb.org/java/current/index.html (In particular the BasicBSONEncoder/Decoder here: api.mongodb.org/java/current/index.html?org/bson/…)? — WiredPrairie

It's fairly simple, you can use the following helper methods:

public static byte[] encode(BSONObject bsonObject) {
    BSONEncoder encoder = new BasicBSONEncoder();
    return encoder.encode(bsonObject);
}

public static BSONObject readObject(InputStream is) throws IOException {
    BasicBSONDecoder encoder = new BasicBSONDecoder();
    return encoder.readObject(is);
}

public static BSONObject readObject(byte[] bsonObject) {
    BasicBSONDecoder encoder = new BasicBSONDecoder();
    return encoder.readObject(bsonObject);
}

When you need binary BSON, i.e., byte array in BSON format, you may use the following pair:

public byte[] DBObjectToBSON(DBObject dbObject) {
    BasicBSONEncoder encoder = new BasicBSONEncoder();
    return encoder.encode(dbObject);
}

public DBObject BSONToDBObject(byte[] bson) {
    BasicBSONDecoder decoder = new BasicBSONDecoder();
    JSONCallback callback = new JSONCallback();
    decoder.decode(bson, callback);
    return (DBObject) callback.get();
}
