title: How to override the default activiti spring-boot configuration
body: <p>I'm working on a Spring Boot application and trying to tweak my Activiti process engine settings. I have added the Activiti dependency to my <code>pom.xml</code> and Boot is able to start and load my <code>BPMN</code> files correctly. </p>
  
  <p>What I would like to do now is to override some of the Spring Boot defaults, for example <code>MailServerHost</code> setting. Is there a way to do that in the <code>application.properties</code> file? I looked around but can't find a reference that lists those properties. I guess I'm looking for something like <a href="https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html]" rel="nofollow">this</a> for the Activiti properties.</p>
