Ya, I'm tring Spring AOP as well, and facing some problem.
If I AOP action class, some action when I run, I got this error, but some is
running fine:

Not sure what happen, but if I AOP service & dao classes, thats fine, but it
print the interface name instead of the actual implement class name.
Here is part of my spring conf:
<bean
class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames">
<list>
<value>*Action*</value>
<value>*Service*</value>
<value>*DAO*</value>
</list>
</property>
<property name="interceptorNames">
<list>
<value>logInterceptor</value>
</list>
</property>
</bean>
And the LogInterceptor.java:
public class LogInterceptor implements MethodInterceptor {
private static Log logger = LogFactory.getLog(LogInterceptor.class);
/*
* (non-Javadoc)
*
* @see
* org.aopalliance.intercept.MethodInterceptor#invoke(org.aopalliance.intercept
* .MethodInvocation)
*/
@Override
public Object invoke(MethodInvocation methodInvocation) throws Throwable {
if (logger.isDebugEnabled()) {
logger.debug("Beginning method: "
+ methodInvocation.getMethod().getClass() + "::"
+ methodInvocation.getMethod().getName());
}
try {
Object returnValue = methodInvocation.proceed();
return returnValue;
} finally {
if (logger.isDebugEnabled()) {
logger.debug("Finish execute "
+ methodInvocation.getMethod().getDeclaringClass()
+ "::" + methodInvocation.getMethod().getName());
}
}
}
}
Print out:
2009-08-18 11:11:00,296 DEBUG louis.common.utils.LogInterceptor.invoke:62 -
Beginning method: class java.lang.reflect.Method::execute
2009-08-18 11:11:00,312 DEBUG louis.common.utils.LogInterceptor.invoke:71 -

No; the logging interceptor does exactly what it says it does.
General declarative entry/exit logging should be handled via AOP, for example
using Spring.
