AOP Logging Advice ignored

[FreddyDaKing]

Hi,

currently I'm trying to use Spring's AOP for logging. I've written some simple test beans and a LoggingInterceptor. I configured everything in in my beans-config.xml. Then I've created the ApplicationContext and called an abitrary method in one of my test beans. The method is called successfully, but I can't see any logging in my console. It seems that my logging advice is completly ignored.

Here my LoggingInterceptor:

import java.lang.reflect.Method;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;
import org.springframework.aop.ThrowsAdvice;

public class LoggingInterceptor implements MethodBeforeAdvice, AfterReturningAdvice, ThrowsAdvice {
  private static Log log = null;

  public LoggingInterceptor() {}

  public void before(Method arg0, Object[] arg1, Object arg2) throws Throwable {
    System.out.println("Entering method: " + arg0.getName());
    log = LogFactory.getLog(arg2.getClass());
    log.info("Entering method: " + arg0.getName());
  }

  public void afterReturning(Object arg0, Method arg1, Object[] arg2, Object arg3) throws Throwable {
    log = LogFactory.getLog(arg3.getClass());
    log.info("Leaving method: " + arg1.getName());
  }

  public void afterThrowing(Method m, Object[] args, Object target, Throwable ex) {
    log = LogFactory.getLog(target.getClass());
    log.info("Exception in method: " + m.getName() + " Exception is: " + ex.getMessage());
  }

}

My Spring configuration is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans

<bean id="loggingInterceptor" class="temp.LoggingInterceptor" />

<bean id="knightWithLogging"
class="org.springframework.aop.framework.ProxyFact oryBean">
<property name="proxyInterfaces">
<value>temp.Knight</value>
</property>
<property name="interceptorNames">
<list>
<value>loggingInterceptor</value>
</list>
</property>
<property name="target" ref="knight" />
</bean>

<bean id="quest" class="temp.HolyGrailQuest" />

<bean id="knight" class="temp.KnightImpl">
<constructor-arg>
<value>Belvidere</value>
</constructor-arg>
<property name="quest">
<ref bean="quest" />
</property>
</bean>

</beans>

Any ideas what the problem could be?

Thx a lot.
