Azure OpenAI RAG with Java, LangChain4J and Quarkus |
A Java sample app that chats with your data using OpenAI. |
⭐ If you like this sample, star it on GitHub — it helps a lot!
This sample shows how to build an AI chat experience with Retrieval-Augmented Generation (RAG) using LangChain4j and OpenAI language models. The application is hosted on Azure Static Web Apps and Azure Container Apps, with Qdrant as the vector database. You can use it as a starting point for building more complex AI applications.
Important
👉 Follow the full-length workshop to learn how we built this sample and how you can run and deploy it.
This sample uses Quarkus to create a Java service that leverage OpenAI SDK and LangChain4j to build a chatbot that will answer questions based on a corpus of documents, with a website to interact with the API.
This project is structured as monorepo, all packages source code is located under the src/ folder.
Here's the architecture of the application:
You can use GitHub Codespaces to work on this project directly from your browser:
You can also use Docker and the Dev Containers extension for VS Code to work locally using a ready-to-use dev environment:
If you prefer to install all the tools locally, you can follow these setup instructions.
Tip
You can run this sample entirely locally without any cost using Ollama. Follow the instructions above to setup the tools locally to get started.
- Azure account. If you're new to Azure, get an Azure account for free to get free Azure credits to get started. If you're a student, you can also get free credits with Azure for Students.
- Azure subscription with access enabled for the Azure OpenAI Service. You can request access with this form.
- Azure account permissions:
- Your Azure account must have
Microsoft.Authorization/roleAssignments/writepermissions, such as Role Based Access Control Administrator, User Access Administrator, or Owner. If you don't have subscription-level permissions, you must be granted RBAC for an existing resource group and deploy to that existing group. - Your Azure account also needs
Microsoft.Resources/deployments/writepermissions on the subscription level.
- Your Azure account must have
Open a terminal and run the following commands:
azd auth login
azd upThis commands will first ask you to log in into Azure. Then it will provison the Azure resources, package the services and deploy them to Azure.
To clean up all the Azure resources created by this sample:
- Run
azd down --purge - When asked if you are sure you want to continue, enter
y
The resource group and all the resources will be deleted.
