title: How to show complete log messages on Spring-boot
body: <p>Most of the messages I looked at in the history are about disabling certain aspects of the log. I'd like the opposite. I'm seeing lots of messages like:</p>
  <blockquote>
  <p>&quot; DEBUG o.s.w.s.m.m.a.HttpEntityMethodProcessor.traceDebug (91) - Writing [&quot;
  &lt;rss xmlns:dc=&quot;http://purl.org/dc/elements/1.1/&quot; version=&quot;2. (truncated)...]&quot;</p>
  </blockquote>
  <p>I'd like to see the entire, non-truncated, (in this case) RSS feed. Any idea how I can persuade Spring/Logback/console/maven to do this?</p>
  <p>Bonus question -- how would I write a test to verify that the logs are actually not truncated? I don't have them persisted in any way, just on the console. Many thanks!</p>
