I was asked in an episode of Spring Office Hours how they could perform reCaptcha verification using Spring Security. This demo and the YouTube tutorial that goes with is my answer to that question.

To perform reCaptcha validation I am using Google reCaptcha v3. You can use the same approach used in this tutorial to plugin whatever verification service you would like to use.

When you create a new reCaptcha service you will be given 2 keys, a site key and a secret key. Before you can run this application you will need to add those keys to the configuration of this project.

Site Key: src/frontend/.env Secret Key: src/main/resources/application.properties

You will need to open a terminal move into the src/frontend directory and run the following commands:

npm install
npm run dev

Once the frontend application is running you can run the Spring Boot application with the following command:

./mvnw spring-boot:run
