title: How to execute sql script after db schema generation but before application startup
body: <p>I want to generate DB structure from my Java classes</p>
  
  <pre><code>jpa.generate-ddl: true
  jpa.ddl-auto: true
  </code></pre>
  
  <p>Also, I need to run SQL script before application will up because I have <code>@PostConstruct</code> methods where I use these data.</p>
  
  <p>Can you show an example how to do it in Spring Boot?</p>
