title: Spring Boot 2.2.5 get post request parameters
body: <p>Is there a way to get request body(JSON) parameters without using a POJO object for each request?
  I have two types of requests, in many of these request what I want is get a parameter from request,
  for example something like this:</p>
  
  <pre><code>{"name": "Mike", "Age":25}
  </code></pre>
  
  <pre class="lang-java prettyprint-override"><code>request.getBodyParameter("name");
  </code></pre>
  
  <p>and for some of my requests I want to convert the input json to a JAVA hash map.</p>
