Example 17 with Advisor

use of cn.taketoday.aop.Advisor in project today-framework by TAKETODAY.

the class AspectJAwareAdvisorAutoProxyCreator method sortAdvisors.

/**
 * Sort the supplied {@link Advisor} instances according to AspectJ precedence.
 * <p>If two pieces of advice come from the same aspect, they will have the same
 * order. Advice from the same aspect is then further ordered according to the
 * following rules:
 * <ul>
 * <li>If either of the pair is <em>after</em> advice, then the advice declared
 * last gets highest precedence (i.e., runs last).</li>
 * <li>Otherwise the advice declared first gets highest precedence (i.e., runs
 * first).</li>
 * </ul>
 * <p><b>Important:</b> Advisors are sorted in precedence order, from highest
 * precedence to lowest. "On the way in" to a join point, the highest precedence
 * advisor should run first. "On the way out" of a join point, the highest
 * precedence advisor should run last.
