MongoDB connection testing fails in Java with the correct credentials for the existing database. A com.mongodb.CommandFailureException .
This may be a mismatch between the different versions of MongoDB, because I use the code written for version 2.6 and run it with version 3 . It is less likely to be between different versions of the MongoDB driver, because I use the same version ( mongo-java-driver 2.12.4 ) in which the code was tested.
What can I do to fix this error and make it compatible with several versions of MongoDB?
String dbName = "test_db"; String host = "localhost"; Integer port = 27017; String username = "admin"; String password = "password"; static Logger log = Logger.getLogger(MongoTest.class.getName()); log.debug("DBNAME:"+dbName+"\nHOST:"+host+"\nPORT:"+port+"\nUSERNAME:"+username+"\nPASSWORD:"+password+"\n"); MongoCredential credential = MongoCredential.createMongoCRCredential(username, dbName, password.toCharArray()); List<MongoCredential> auths = new ArrayList<MongoCredential>(); auths.add(credential); MongoClient mongo = new MongoClient(new ServerAddress(host, port), auths); DB db = mongo.getDB(dbName); log.debug("DB:"+db);
