title: Disable the Number to String automatic conversion in jackson
body: <p>When I make a json request to a spring boot backend, Jackson is automatically converting numbers to strings. Is there a way to prevent that?</p>
  
  <p>For example:</p>
  
  <p><strong>JSON</strong></p>
  
  <pre><code>{
      "numberAsString": 123
  }
  </code></pre>
  
  <p><strong>JAVA</strong></p>
  
  <pre><code>private String numberAsString;
  </code></pre>
  
  <p>after binding json value to the java field <code>numberAsString</code> is equal to <code>"123"</code>. i need to prevent this automatic conversion and need to throw some kind of a exception when this happens.</p>
