BSON naar JSON-conversie met MongoDB Driver Java API

De toJson-methode van BSON Documnet ondersteunt alleen uitvoer naar MongoDB Extended JSON (STRIK of SHELL-formaat). Als u reguliere JSON wilt hebben, kunt u com.mongodb.util.JSON gebruiken klas:

String input = "{ \"timestamp\" : 1486064586641 }";
org.bson.Document doc = org.bson.Document.parse(input);
System.out.println("input  = " + input);
System.out.println("output (SHELL) = " + doc.toJson(new JsonWriterSettings(JsonMode.SHELL)));
System.out.println("output (STRICT) = " + doc.toJson(new JsonWriterSettings(JsonMode.STRICT)));
System.out.println("output (JSON) = " + com.mongodb.util.JSON.serialize(doc));

Dit zal de volgende output genereren:

input  = { "timestamp" : 1486064586641 }
output (SHELL) = { "timestamp" : NumberLong("1486064586641") }
output (STRICT) = { "timestamp" : { "$numberLong" : "1486064586641" } }
output (JSON) = { "timestamp" : 1486064586641}
