Using Vault in Spring applications

These assets demonstrate how to use Vault in Spring applications.

Each subdirectory includes assets to do the following:

• vault-transit/: Encrypt and decrypt application payloads with Vault transit secrets engine

Setup

1. Install Docker Compose.

2. Run Docker Compose to set up application dependencies.

   $ docker compose up -d

3. Run the application using Maven Wrapper.

   $ ./mvnw spring-boot:run

Sample Application

Each project uses a sample application with the following API:

• Get payments

$ curl localhost:8080/payments

[{"cc_info":"4242424242424242","id":"b7703d9a-ff7b-4898-91ba-4b5adba8b7e5","name":"Test Customer","createdAt":"2024-05-09T17:51:21.099933Z"}]

• Create a payment

$ curl -XPOST -d '{"name": "Test Customer", "cc_info": "4242424242424242"}' -H 'Content-Type:application/json' localhost:8080/payments

[{"cc_info":"4242424242424242","id":"b7703d9a-ff7b-4898-91ba-4b5adba8b7e5","name":"Test Customer","createdAt":"2024-05-09T17:51:21.099933Z"}]

The application requires the following dependencies:
