使用过滤器记录来自flex / BlazeDS客户端的所有请求

Question

我有一个spring BlazeDS集成应用程序。我想记录所有的请求。

我计划使用Filter。在我的过滤器中，当我检查请求参数时。它不包含任何与客户端请求相关的内容。如果我改变我的过滤器的顺序(我有spring Security)，那么它会打印一些与spring Security相关的东西。

我无法记录用户请求。

我通过使用AOP (AspectJ)将记录器语句注入通信端点方法来实现相同的功能。——希望这对你来说也是另一种方法。

/** 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.
     * 
     * Flex remoting methods are determined by two constraints:
     * <ul>
     *   <li>they are public</li>
     *   <li>the are located in a class of name Remoting* within (implement an interface)
     *   {@link com.example.remote} package</li>
     *   <li>they are located within a class with an {@link RemotingDestination} annotation</li>
     * </ul>
     */
    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);            
        }
    }
}
