MongoDB Java Reactive Streams¶
Introduction¶
Java Reactive Streams is an official Java driver for MongoDB and is the recommended driver for working with reactive streams in the JVM ecosystem.
Installation¶
The recommended way to get started using the driver in your project is with a dependency management system. See the Installation Guide for more information.
Connect to MongoDB Atlas¶
To connect to a MongoDB Atlas cluster, use the Atlas connection string for your cluster:
import com.mongodb.ConnectionString; import com.mongodb.client.MongoClients; import com.mongodb.client.MongoClient; import com.mongodb.client.MongoDatabase; import com.mongodb.MongoClientSettings; // ... ConnectionString connString = new ConnectionString( "mongodb+srv://<username>:<password>@<cluster-address>/test?w=majority" ); MongoClientSettings settings = MongoClientSettings.builder() .applyConnectionString(connString) .retryWrites(true) .build(); MongoClient mongoClient = MongoClients.create(settings); MongoDatabase database = mongoClient.getDatabase("test");
See Connect to MongoDB for more ways to connect.
