Spring: Standard Logging aspect (interceptor)

Yes there are!

<bean id="customizableTraceInterceptor" class="org.springframework.aop.interceptor.CustomizableTraceInterceptor">    <property name="enterMessage" value="Entering $[methodName]($[arguments])"/>    <property name="exitMessage" value="Leaving $[methodName](): $[returnValue]"/></bean><aop:config>    <aop:advisor advice-ref="customizableTraceInterceptor" pointcut="execution(public * BankAccountServlet.*(..))"/></aop:config>

Check out the CustomizableTraceInterceptor API, you can define separate enter/exit/exception messages with several placeholders:

• $[methodName] - replaced with the name of the method being invoked
• $[targetClassName] - replaced with the name of the class that is the target of the invocation
• $[targetClassShortName] - replaced with the short name of the class that is the target of the invocation
• $[returnValue] - replaced with the value returned by the invocation
• $[argumentTypes] - replaced with a comma-separated list of the short class names of the method arguments
• $[arguments] - replaced with a comma-separated list of the String representation of the method arguments
• $[exception] - replaced with the String representation of any Throwable raised during the invocation
• $[invocationTime] - replaced with the time, in milliseconds, taken by the method invocation

Here are the list of frameworks that do logging via AOP:

http://aspect4log.sf.net - does very nice looking logging via slf4j and @Log annotation. Can work via SpringAOP, and AspectJ. With AspectJ it works even for private methods and constructors and does not require a class to be a Spring Bean. Very easy to use, i was able to make it running with my project within 5 min.

http://loggifier.unkrig.de - does logging via java.util.logging, a bit too complex and not that well document but claims that it can instrument already compiled jar/war/ear files!

AbstractTraceInterceptor (from SpringAOP) and it's subclasses SimpleTraceInterceptor and CustomizableTraceInterceptor. Logging configuration is done separately from classes. Logs via commons-logging. Since it is designed for SpringAOP you have to work with Spring Beans (and only with Spring Beans public methods).
