title: Recommendations for cron-like scheduling in Grails: run method once every hour
body: <p>Suppose I want to run the following method <code>foo()</code> once every hour in Grails:</p>
  
  <pre><code>class FooController {
    public static void foo() {
      // stuff that needs to be done once every hour (at *:00)
    }
  }
  </code></pre>
  
  <p>What is the easiest/recommended way to set up such cron-like scheduling in Grails?</p>
