title: how to extend method afterPropertiesSet()
body: <p>In my spring configuration I define bean  </p>
  
  <pre><code>bean id="com.companyName.schedulerBean"
      class="org.springframework.scheduling.quartz.SchedulerFactoryBean"
  </code></pre>
  
  <p>I want to extend logic of method <code>SchedulerFactoryBean.afterPropertiesSet()</code>. 
  If there any way to do it?</p>
  
  <p>For example now <code>SchedulerFactoryBean.afterPropertiesSet()</code> does logic:</p>
  
  <ol>
  <li>initialize schedulerFactory and Scheduler</li>
  <li>registerJobDetails</li>
  </ol>
  
  <p>I want such method logic:</p>
  
  <ol>
  <li>initialize schedulerFactory and Scheduler</li>
  <li>remove existing jobs</li>
  <li>registerJobDetails</li>
  </ol>
  
  <p>Thanks in advance.</p>
  
  <p>p.s. Sorry for my english.</p>
