  1. POwhy is this Spring AOP pointcut not triggered?
    text
    copied!<p>I'm writing very basic schema-based Spring AOP, here's the .xml</p> <pre class="lang-xml prettyprint-override"><code>&lt;bean id="aoplistener" class="tao.zhang.Listener"/&gt; &lt;aop:config&gt; &lt;aop:aspect ref="aoplistener"&gt; &lt;aop:pointcut id="whenCalled" expression="execution(* callme(..))" /&gt; &lt;aop:after method="scream" pointcut-ref="whenCalled" /&gt; &lt;/aop:aspect&gt; &lt;/aop:config&gt; </code></pre> <p>The method <strong>scream()</strong> in tao.zhang.Listener just prints out some text, <strong>and is supposed to be executed whenever a method callme() is called.</strong></p> <p>I have a bean called <strong>logger</strong> which has the methods log() and callme()</p> <pre class="lang-java prettyprint-override"><code>public void log(){ callme(); System.out.println("Hello from logger ~~~~~~~~~~~~~~~~~~~"); } public void callme(){ System.out.println("I'm called"); } </code></pre> <p>Note that callme() is called by log()</p> <p>Now I have a scheduler which calls log() every 5 seconds:</p> <pre class="lang-xml prettyprint-override"><code>&lt;task:scheduler id="myScheduler" pool-size="10"/&gt; &lt;task:scheduled-tasks scheduler="myScheduler"&gt; &lt;task:scheduled ref="logger" method="log" fixed-rate="5000"/&gt; &lt;/task:scheduled-tasks&gt; </code></pre> <p>Strangely, <strong>scream()</strong> is not invoked, but if callme() is called directly:</p> <pre class="lang-xml prettyprint-override"><code>&lt;task:scheduler id="myScheduler" pool-size="10"/&gt; &lt;task:scheduled-tasks scheduler="myScheduler"&gt; &lt;task:scheduled ref="logger" method="callme" fixed-rate="5000"/&gt; &lt;/task:scheduled-tasks&gt; </code></pre> <p><strong>scream()</strong> is invoked!</p> <p>Any suggestions? It seems to me that this pointcut doesn't match methods called inside another method ...</p>
