Introduction

Couchbase is a high-performance NoSQL database known for its scalability and flexibility. Integrating Couchbase with Spring Boot allows you to leverage the benefits of NoSQL data storage in your applications. This guide walks through the configuration, implementation of repositories, and practical examples for seamless Couchbase integration.

Configuring Couchbase with Spring Boot

1. Add Dependencies

Include the required dependencies for Couchbase in your pom.xml:

2. Set Up Configuration Properties

Configure Couchbase details in application.properties:

3. Couchbase Configuration Class

Define a custom configuration class if you need additional setup:

Implementing Repositories

1. Define an Entity

Create an entity class annotated with @Document to map Couchbase documents.

2. Create a Repository Interface

Use Spring Data Couchbase to create a repository for CRUD operations.

Practical Examples

Save and Retrieve Data

Service Class

REST Controller

Test the API

1. Save a Product:

   • Send a POST request to /products with a JSON body:

2. Retrieve a Product:

   • Send a GET request to /products/1 to fetch the saved product.

Conclusion

Integrating Couchbase with Spring Boot is straightforward with Spring Data Couchbase. By setting up configuration, defining entities, and using repositories, you can perform CRUD operations efficiently. This guide provides a foundation for leveraging Couchbase in your Spring Boot applications.
