title: Limit write size of String with jackson
body: <p>I have a list of objects with a field "description". This field can be huge (+3000 char) but I use it in the preview (I display only the 100 firsts char).</p>
  
  <p>Is there a way in jackson to limit the size of a String on write ? I only want jackson to crop it to 100 chars. (No bean validation required here).</p>
  
  <p>For exemple, if I have an object like this :</p>
  
  <pre><code>{
      "description" : "bla bla bla bla... + 3000 char"
  }
  </code></pre>
  
  <p>Ideally I want it be cropped like thie :</p>
  
  <pre><code>{
      "description" : bla bla [max 100 chars] bla..."
  }
  </code></pre>
  
  <p>Thank you.</p>
