Question

使用正确的现有数据库登录凭据，Java中的MongoDB连接测试失败。显示Load。

这可能是不同版本的MongoDB之间的不匹配，因为我使用的是为 2.6 版本编写的代码，并使用版本 3 运行它。它不太可能介于不同版本的MongoDB驱动程序之间，因为我使用的是与测试代码相同的版本（com.mongodb.CommandFailureException）。

如何修复此错误并使其与一系列MongoDB版本兼容？

mongo-java-driver 2.12.4

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); // not null DBCollection dbCollection = db.createCollection("__test__", new BasicDBObject()); // FAIL：

mongo.log

例外：

通过在Mongo（3.0.7）CLI中正确添加用户来解决问题，我尝试在admin数据库上运行它，而它应该在test_db数据库上：

mongo --authenticationDatabase db_name -u username -p password
(Connected to Mongo CLI client...)
> use test-db;
> db.createUser( 
  { 
    "user" : "admin", 
    "pwd": "password",  
    "roles" : [      
      { role: "root", db: "admin" },
      { role: "readWrite", db: "admin" }, 
      { role: "dbAdmin", db: "admin" },
      { role: "readWrite", db: "test_db" }, 
      { role: "dbAdmin", db: "test_db" }
    ]  
});
(Success...)
> db.auth("admin","password")
