title: Explain the structure of spring project?
body: <p>I am new to Spring and just created a project using Spring CLI.  </p>
  
  <p>When I opened the project using STS i see the following folder structure.
  There are two <code>src</code> folders.</p>
  
  <p>What is the difference between them ? <code>src/main/java</code> and just <code>src</code>.</p>
  
  <p>Also suppose I want to create a new folder like <code>webapp</code> under <code>main</code>, where should I create it ?<br>
  I looked a lot online but couldn't find any answers.</p>
  
  <p>Please help.</p>
