MongoClient

java.lang.Object
- com.mongodb.Mongo
- - com.mongodb.MongoClient

All Implemented Interfaces:

Closeable, AutoCloseable
```
public class MongoClient
extends Mongo
implements Closeable
```
A MongoDB client with internal connection pooling. For most applications, you should have one MongoClient instance for the entire JVM.
The following are equivalent, and all connect to the local database running on the default port:
```
 MongoClient mongoClient1 = new MongoClient();
 MongoClient mongoClient1 = new MongoClient("localhost");
 MongoClient mongoClient2 = new MongoClient("localhost", 27017);
 MongoClient mongoClient4 = new MongoClient(new ServerAddress("localhost"));
 MongoClient mongoClient5 = new MongoClient(new ServerAddress("localhost"), MongoClientOptions.builder().build());
 
```
You can connect to a replica set using the Java driver by passing a ServerAddress list to the MongoClient constructor. For example:
```
 MongoClient mongoClient = new MongoClient(Arrays.asList(
   new ServerAddress("localhost", 27017),
   new ServerAddress("localhost", 27018),
   new ServerAddress("localhost", 27019)));
 
```
You can connect to a sharded cluster using the same constructor. MongoClient will auto-detect whether the servers are a list of replica set members or a list of mongos servers.

By default, all read and write operations will be made on the primary, but it's possible to read from secondaries by changing the read preference:
```
 mongoClient.setReadPreference(ReadPreference.secondaryPreferred());
 
```
By default, all write operations will wait for acknowledgment by the server, as the default write concern is WriteConcern.ACKNOWLEDGED.

Note: This class supersedes the Mongo class. While it extends Mongo, it differs from it in that the default write concern is to wait for acknowledgment from the server of all write operations. In addition, its constructors accept instances of MongoClientOptions and MongoClientURI, which both also set the same default write concern.

In general, users of this class will pick up all of the default options specified in MongoClientOptions. In particular, note that the default value of the connectionsPerHost option has been increased to 100 from the old default value of 10 used by the superseded Mongo class.
Since:

2.10.0

  - MongoClient
```
public MongoClient(List<ServerAddress> seeds)
```
    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 MongoClient(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.
