How to test equality of MongoDB filters (BSON) in Java/Groovy? -

i'm generating mongodb-queries unsing filters-api.

bson r1 = filters.and(filters.eq("a","b"), filters.eq("c","d")) bson r2 = filters.and(filters.eq("a","b"), filters.eq("c","d")) 

but how can check result equality? example:

r1.equals(r2) 

and

r1.dump().equals(r2.dump()) 

don't work.

one thing is:

• convert bson bsondocument
• compare json strings

here found on https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/mongodb-user/peel8wiwxwa/zhpyglqedqaj

bsondocument b1 = r1.tobsondocument(bsondocument.class, mongoclient.default_codec_registry); bsondocument b2 = r2.tobsondocument(bsondocument.class, mongoclient.default_codec_registry);
