title: Serializing array with Jackson
body: <p>I'm serializing the following model:</p>
  
  <pre><code>class Foo {
  
      private List&lt;String&gt; fooElements;
  }
  </code></pre>
  
  <p>If <code>fooElements</code> contains the strings 'one', 'two' and 'three. The JSON contains one string:</p>
  
  <pre><code>{
      "fooElements":[
           "one, two, three"
       ]
  }
  </code></pre>
  
  <p>How can I get it to look like this:</p>
  
  <pre><code>{
      "fooElements":[
           "one", "two", "three"
       ]
  }
  </code></pre>
