Class Mongo

java.lang.Object
com.mongodb.Mongo
Direct Known Subclasses:
MongoClient
@ThreadSafe @Deprecated public class Mongo extends Object
Deprecated.
Replaced by MongoClient. Any non-deprecated methods will be moved to MongoClient. The rest will be removed along with this class.

A database connection with internal connection pooling. For most applications, you should have one Mongo instance for the entire JVM.

Note: This class has been superseded by MongoClient, and may be deprecated in a future release.

      @Deprecated public Mongo(ServerAddress left, ServerAddress right)
      Deprecated.
      Please use MongoClient(java.util.List) instead.

      Creates a Mongo in paired mode.

      This will also work for a replica set and will find all members (the master will be used by default).

      Parameters:
      left - left side of the pair

      Creates a Mongo connection in paired mode.

      This will also work for a replica set and will find all members (the master will be used by default).

      Parameters:
      left - left side of the pair

      options - the optional settings for the Mongo instance

    • Mongo

      @Deprecated public Mongo(List<ServerAddress> seeds)
      Deprecated.
      Replaced by MongoClient(java.util.List)

      Creates an instance based on a list of replica set members or mongos servers. For a replica set it will discover all members. For a list with a single seed, the driver will still discover all members of the replica set. For a direct connection to a replica set member, with no discovery, use the Mongo(ServerAddress) constructor instead.

      When there is more than one server to choose from based on the type of request (read or write) and the read preference (if it's a read request), the driver will randomly select a server to send a request. This applies to both replica sets and sharded clusters. The servers to randomly select from are further limited by the local threshold. See MongoClientOptions.getLocalThreshold()

      Parameters:
      seeds - Put as many servers as you can in the list and the system will figure out the rest. This can either be a list of mongod servers in the same replica set or a list of mongos servers in the same sharded cluster.

    • Mongo

      @Deprecated public Mongo(MongoURI uri)
      Deprecated.
      Replaced by MongoClient(MongoClientURI)

      Creates a Mongo described by a URI. If only one address is used it will only connect to that node, otherwise it will discover all nodes. If the URI contains database credentials, the database will be authenticated lazily on first use with those credentials.

      Examples:

      • mongodb://localhost
      • mongodb://fred:foobar@localhost/
      Parameters:
      uri - URI to connect to, optionally containing additional information like credentials
      Throws:
      MongoException - if there's a failure
