title: Spring - Could not find key 'could not find key 'logging.exception-conversion-word'
body: <p>My Spring-Boot-Batch app is running fine, and it appears all logging is working as expected. I am using Logback and have a logback-spring.xml file that is being read and appears to be setting everything up correctly. However, every time I run the program get the following: </p>
  
  <pre><code>13:12:32.538 [main] DEBUG org.springframework.core.env.PropertySourcesPropertyResolver - Could not find key 'logging.exception-conversion-word' in any property source
  13:12:32.553 [main] DEBUG org.springframework.core.env.PropertySourcesPropertyResolver - Could not find key 'logging.pattern.console' in any property source

  </code></pre>
  
  <p>I do not have said properties in my files, so it is correct in that statement, but what I can not find through Google searching is: What is looking for those properties? Since I do not seem to need said properties, how do I stop it from looking for them? If I need to add them, what are the possible values and how are they being used? </p>
  
  <p>None of my other Spring-Boot-Batch applications have these properties, nor are they throwing this error. </p>
