title: where is port 8080 defined in spring cloud app?
body: <p>I have been doing a line by line study of the code in <a href="https://github.com/spring-guides/tut-spring-security-and-angular-js/tree/master/oauth2" rel="nofollow">this spring cloud app on github</a> after downloading and installing it on my devbox.  When you type <code>http://localhost:8080</code> in your web browser, the content from the <code>ui</code> app loads, and is able to interact with the content from the <code>authserver</code> and <code>resource</code> apps.  </p>
  
  <p><code>Port 9999</code> is defined for the <code>authserver</code> app, both in the <code>ui</code> app's <code>zuul route</code> definitions, and also in the <code>authserver</code> app's <code>application.properties</code>.  </p>
  
  <p>Similarly, <code>port 9000</code> is defined for the <code>resource</code> app, both in the <code>ui</code> app's route definitions, and also in the <code>resource</code> app's <code>application.properties</code>.  </p>
  
  <p>But I cannot find any reference to <code>port 8080</code>, even after reviewing every line of code in the three apps and also doing a <code>Ctrl-H</code> to do full text search of the entire eclipse workspace for the word <code>8080</code>.  </p>
  
  <p><strong>So how does the <code>ui</code> app know to serve its client content on <code>port 8080</code>?</strong></p>
