Log all request from flex / BlazeDS client using filter


I have a spring BlazeDS integration application. I would like to log all the request.

I planned to use Filter. In my filter when I check the request parameter. It does not contain anything related to the client request. If I change the order of my filter(I have spring Security), then it prints some thing related to spring security.

I am unable to log the user request.

Any help is appreciated.


Solution

  • I have done the same functionality by using AOP (AspectJ) to inject a logger statement into communication endpoint methods. -- May this is an alternative approach for you too.


    /** Logger advice and pointcuts for flex remoting stuff based on aspect J*/
    public aspect AspectJInvocationLoggerAspect {
    
        /** The name of the used logger. */
        public final static String LOGGER_NAME = "myPackage.FLEX_INVOCATION_LOGGER";
    
        /** Logger used to log messages. */
        private static final Logger LOGGER = Logger.getLogger(LOGGER_NAME);
    
        AspectJInvocationLoggerAspect() {
        }
    
        /**
         * Pointcut for all flex remoting methods.

        pointcut remotingServiceFunction()
            : (execution(public * com.example.remote.*.*Remote*.*(..)))  
            && (within(@RemotingDestination *));
    
        before() : remotingServiceFunction() {
            if (LOGGER.isDebugEnabled()) {
                Signature sig = thisJoinPointStaticPart.getSignature();
                Object[] args = thisJoinPoint.getArgs();
    
                String location = sig.getDeclaringTypeName() + '.' + sig.getName() + ", args=" + Arrays.toString(args);            
                LOGGER.debug(location + " - begin");
            }
        }
    
        /** Log flex invocation result at TRACE level. */
        after() returning (Object result): remotingServiceFunction() {
    
            if (LOGGER.isTraceEnabled()) {
                Signature sig = thisJoinPointStaticPart.getSignature();            
    
                String location = sig.getDeclaringTypeName() + '.' + sig.getName();
                LOGGER.trace(location + " - end = " + result);            
            }
        }
    }
