Introduction

Integrating Stripe with Spring Boot allows businesses to handle payment processing, including one-time charges, recurring subscriptions, and more. Stripe is a widely used payment gateway that provides robust APIs for managing online payments. This guide will demonstrate how to integrate Stripe with Spring Boot to manage transactions and handle common payment tasks such as creating charges, handling webhooks, and managing subscriptions.

Setting Up Stripe in Spring Boot

Step 1: Add Stripe Dependency

First, include the Stripe SDK in your pom.xml file to get access to the Stripe API.

Step 2: Configure Stripe API Keys

Add your Stripe secret key and publishable key in application.properties.

In the @Configuration class, set up Stripe with your secret key.

Creating a Charge with Stripe in Spring Boot

Step 3: Create a Payment Endpoint

Now, let’s create an endpoint to handle the payment requests. This endpoint will accept a payment method ID (from the frontend) and create a charge using Stripe’s Charge API.

This controller accepts a paymentMethodId (which is generated on the frontend using Stripe’s JavaScript SDK) and uses it to create a PaymentIntent.

Handling Stripe Webhooks in Spring Boot

Step 4: Set Up Webhook for Payment Confirmation

Webhooks are essential for receiving notifications from Stripe when certain events occur, such as a successful payment or a failed payment. To set this up:

1. Create a webhook endpoint in your Spring Boot application.

In this example:

• The handleWebhook method listens for incoming Stripe events.
• It verifies the event’s authenticity using the Stripe-Signature header.
• Then, it processes different types of events (e.g., payment_intent.succeeded, payment_intent.payment_failed).

Step 5: Testing the Webhook

To test webhooks locally, you can use Stripe's CLI to forward events to your local development server:

Implementing Recurring Payments with Stripe

Step 6: Set Up a Subscription

To create a recurring payment (subscription), follow these steps:

1. Create a Product and Price in Stripe Dashboard: First, create a product and its corresponding price in the Stripe dashboard.
2. Create a Subscription in Spring Boot:

This endpoint creates a subscription for a customer using the payment method.

Conclusion

Integrating Stripe with Spring Boot for payment processing is straightforward with Stripe’s extensive API and the Spring Boot framework. You can easily create one-time charges, handle recurring subscriptions, and process webhook events to stay updated on payment statuses. By using Spring Boot’s powerful tools, you can manage payments securely and efficiently, ensuring a smooth payment experience for users.
