title: Spring Boot - How to define application.yml properties as application.properties
body: <p>I am currently trying to set up an s3 bucket with my Spring Boot webapp for adding/removing images. </p>
  
  <p>The guide I am following uses the following application.yml properties: </p>
  
  <pre><code>amazonProperties:
    endpointUrl: https://s3.us-east-2.amazonaws.com
    accessKey: XXXXXXXXXXXXXXXXX
    secretKey: XXXXXXXXXXXXXXXXXXXXXXXXXX
    bucketName: your-bucket-name
  </code></pre>
  
  <p>How can I define these properties in my application.properties file?</p>
  
  <p>All help is very much appreciated, thank you! </p>
