title: Create static content with images and videos and show it in my spring-boot application
body: <p>I wrote some basic blog system, which based on spring boot.
  I'm trying to figure out, how can I create posts with videos and images, without the need to editing everything using HTML.</p>
  
  <p>Right now, I am saving my blog posts in DB as plain text.
  Is it possible to create content combined with text, images and videos , and saving this "content" as one row in my DB-Table, without creating connections between different tables?</p>
  
  <p>Many thanks in advance. </p>
