title: spring-boot-devtools doesn't seem to work when i run myJhipsterApp as maven build:spring-boot:run
body: <p>I have generated a blog app   following a video tutorials of jhipster4 blog demo ,but once i change the .html or .java files in eclipse, the spring-boot did not automatically deploy the changes ,as a result there was nothing changed when i refresh the browser </p>
  
  <p>this is the pom.xml ,</p>
  
  <pre><code>  &lt;dependency&gt;
                      &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
                      &lt;artifactId&gt;spring-boot-devtools&lt;/artifactId&gt; 
                      &lt;optional&gt;true&lt;/optional&gt;
                  &lt;/dependency&gt;
  </code></pre>
