You can set timeouts by using the Mongo Java client's MongoClientOptions. For example:
MongoClientOptions clientOptions = MongoClientOptions.builder()
.connectTimeout(...)
.socketTimeout(...)
.serverSelectionTimeout(...)
.build();
MongoClient mongoClient = new MongoClient(new ServerAddress(host, port), clientOptions);
Examining mongoClient.getMongoClientOptions() after the above line of code clearly shows that the created client is faithful to the supplied config values. By contrast, if you do not set these values via MongoClientOptions then mongoClient.getMongoClientOptions() shows that the default values have been chosen.
Based on your updated comments I think the situation you are trying to cater for is this:
Creating a connection against a server instance which does not exists / is unavailable should fail sooner that the default of 30s.
If so then the configuration parameter you want to use is serverSelectionTimeout. The following invocation ...
MongoClientOptions clientOptions = MongoClientOptions.builder()
.serverSelectionTimeout(2000)
.build();
MongoClient mongoClient = new MongoClient(new ServerAddress(host, port), clientOptions);
... will cause this exception to be thrown:
com.mongodb.MongoTimeoutException: Timed out after 2000 ms while waiting to connect.
Note: serverSelectionTimeout is available in the version of the MongoDB Java driver which you are using (3.2.2 according to the comment you posted on your question).
