Environment:MacOS Mojave 10.14.6, Java 1.8, Driver 3.12.5, Mongo 3.6.17-ent single node replicaset
Working with customer to upgrade a data access layer Java class. Trying to implement consistency across the board. I have elected to use the Bson query helpers defined in "org.bson.conversions.Bson.Filters". I am converting use of BasicDBObject and encountered a difference. For this reason I am creating this ticket. This might be a known behavior or might be a discovered bug - I will let you decide! Here are the details...
Consider the following unit test...
@Test public void mytest() { com.mongodb.MongoClientSettings mongoClientSettings = com.mongodb.MongoClientSettings.builder() .applyConnectionString(new com.mongodb.ConnectionString("mongodb://testuser:mysecret@localhost:27017/?replicaSet=replSet&w=majority&readConcernLevel=majority&readPreference=primary&authSource=admin&retryWrites=true&maxPoolSize=10&waitQueueTimeoutMS=1000")) .build(); com.mongodb.client.MongoClient client = com.mongodb.client.MongoClients.create(mongoClientSettings); com.mongodb.client.MongoDatabase db = client.getDatabase("javatest"); com.mongodb.client.MongoCollection<org.bson.Document> collection = db.getCollection("troubleshooting"); collection.deleteMany(new org.bson.BsonDocument()); org.bson.Document insertedDocument = new org.bson.Document(); insertedDocument.append("field1", 1); collection.insertOne(insertedDocument); Object value = new Object(); value = new Integer[] {4, 5, 6}; BasicDBObject filter = new BasicDBObject("field1", new BasicDBObject("$nin", value)); com.mongodb.client.FindIterable<org.bson.Document> iterable1 = collection.find(filter); try(com.mongodb.client.MongoCursor<org.bson.Document> cursor1 = iterable1.iterator()) { while (cursor1.hasNext()) { org.bson.Document queriedDocument1 = cursor1.next(); System.out.println(String.format("queriedDocument1: %s", queriedDocument1)); } } }
If I change the filter predicate to use the Filters helper Bson object..
@Test public void mytest() { com.mongodb.MongoClientSettings mongoClientSettings = com.mongodb.MongoClientSettings.builder() .applyConnectionString(new com.mongodb.ConnectionString("mongodb://testuser:mysecret@localhost:27017/?replicaSet=replSet&w=majority&readConcernLevel=majority&readPreference=primary&authSource=admin&retryWrites=true&maxPoolSize=10&waitQueueTimeoutMS=1000")) .build(); com.mongodb.client.MongoClient client = com.mongodb.client.MongoClients.create(mongoClientSettings); com.mongodb.client.MongoDatabase db = client.getDatabase("javatest"); com.mongodb.client.MongoCollection<org.bson.Document> collection = db.getCollection("troubleshooting"); collection.deleteMany(new org.bson.BsonDocument()); org.bson.Document insertedDocument = new org.bson.Document(); insertedDocument.append("field1", 1); collection.insertOne(insertedDocument); Object value = new Object(); value = new Integer[] {4, 5, 6}; org.bson.conversions.Bson filter = com.mongodb.client.model.Filters.nin("field1", value); com.mongodb.client.FindIterable<org.bson.Document> iterable1 = collection.find(filter); try(com.mongodb.client.MongoCursor<org.bson.Document> cursor1 = iterable1.iterator()) { while (cursor1.hasNext()) { org.bson.Document queriedDocument1 = cursor1.next(); System.out.println(String.format("queriedDocument1: %s", queriedDocument1)); } } }
