MongoDB JVM Showcase

A collection of example projects showing how to use MongoDB with JVM languages and frameworks.

Each project is independent and self-contained, with its own source code, documentation, and build configuration.

Contents

This repo is organized by language (Java and Kotlin), and inside each language projects are grouped by driver or framework:

Folder	Description
java	Java examples: driver usage, Spring (Data, AI, LangChain4j), Quarkus, and complete use cases.
kotlin	Kotlin examples: driver usage, Ktor, Quarkus, and complete use cases.
workshops	Self-paced hands-on workshops (Java, Kotlin, etc.).

Both languages follow the same structure:

Folder	Description
java-driver / kotlin-driver	Examples using the official MongoDB drivers directly (CRUD, aggregations, MongoDB Search, encryption, etc.).
spring	Spring-based projects: spring-data (Spring Data MongoDB), spring-ai (RAG, vector search), and langchain4j integrations.
quarkus	Quarkus projects.
ktor	Ktor projects (Kotlin).
use-cases	Complete, runnable applications solving real-world scenarios (e.g. fraud detection, movie recommendation).
