MongoDB Java Driver

Welcome to the documentation site for the Java Driver, the official MongoDB driver for synchronous Java applications. Download it using Maven or Gradle, or set up a runnable project by following our Quick Start guide.

If your Java application requires asynchronous stream processing, use the Reactive Streams Driver which uses Reactive Streams to make non-blocking calls to MongoDB.

You can use the Java Driver to connect to deployments hosted in the following environments:

  • MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

  • MongoDB Enterprise: The subscription-based, self-managed version of MongoDB

  • MongoDB Community: The source-available, free-to-use, and self-managed version of MongoDB

Learn how to establish a connection to MongoDB Atlas and begin working with data in the Quick Start section.

See driver syntax examples for common MongoDB commands in the Quick Reference section.

For a list of new features and changes in each version, see the What's New section.

For fully runnable code snippets and explanations for common methods, see the Usage Examples section.

Learn how to perform the following tasks using the Java driver in the Fundamentals section:

The MongoDB Java driver API documentation contains several libraries organized by functionality. For detailed information about classes and methods in each library, see the following table for their descriptions and links to the API documentation.

Base BSON classes
Classes that support records
Shared core classes
Modern API
Legacy API

For answers to commonly asked questions about the MongoDB Java Driver, see the Frequently Asked Questions (FAQ) section.

For solutions to some issues you might see when connecting to a MongoDB deployment while using the MongoDB Java Driver, see Connection Troubleshooting.

Learn how to report bugs, contribute to the driver, and find additional resources for asking questions and receiving help in the Issues & Help section.

For the compatibility charts that show the recommended Java Driver version for each MongoDB Server version, see the Compatibility section.

Learn what changes you may need to make to your application to upgrade driver versions in the Upgrade Driver Versions section.

Learn what changes you may need to make to your application to migrate from the legacy API to the current API in the Migrate from the Legacy API section.
