Advisor summary

It's been a while since the last post, I've been busy with my new assignment that begun right after my vacation. Anyway, here a nifty little routine to quickly get an overview of which beans are woven by what advice, and also what advice weaves which beans in a Spring context:

ApplicationContext context = ... ;  // Create your context 

String perBeanSummary = "--- Advisors per bean ---\n";
Map<String,Advised> beanMap = BeanFactoryUtils.beansOfTypeIncludingAncestors(context, Advised.class);
Map<Advisor,Set<String>> advisorMap = new HashMap<Advisor, Set<String>>();

// This gathers advisors per bean and beans per advisors,
// and builds the presentation of advisors per bean 
for (String beanName : beanMap.keySet()) {
  Advised advised = beanMap.get(beanName);
  perBeanSummary += beanName + ":\n\t";
  for (Advisor advisor : advised.getAdvisors()) {
    perBeanSummary += advisor.getAdvice().getClass().getName() + "\n";
    Set<String> beans = advisorMap.get(advisor);
    if (beans == null) {
      beans = new HashSet<String>();
      advisorMap.put(advisor, beans);
    }
    beans.add(beanName);
  }
  perBeanSummary += "\n";
}

// Builds the presentation of beans per advisor
String perAdvisorSummary = "+++ Beans per advisor +++\n";
for (Advisor advisor : advisorMap.keySet()) {
  perAdvisorSummary += advisor.getAdvice().getClass().getName() + "\n";
  for (String beanName : advisorMap.get(advisor)) {
    perAdvisorSummary += "\t" + beanName + "\n";
  }
  perAdvisorSummary += "\n";
}

System.out.println(perBeanSummary);
System.out.println(perAdvisorSummary);
