title: JSON as String in Spring Integration
body: <p>I use a <code>int:gateway</code>  to bring in a json String into a <code>int:channel</code>. When I print this json String using <code>&lt;int-stream:stdout-channel-adapter/&gt;</code> (or even if I print it inside a service activator attached to <code>int:channel</code>) it is printing key/value pairs with <code>=</code> instead of <code>:</code>
  For example -&gt; <code>GenericMessage [payload={id=1596096, key=SOME_KEY, address={first_name=John, last_name=......</code>
  To solve this problem I have to use a <code>&lt;int:object-to-json-transformer /&gt;</code></p>
  <p>What is the best way to work with raw JSON? My use case is to do a JSON to JSON transformation (also using a splitter).</p>
