以下是我的方面：

    @Configurable
    @Aspect
    public class TimingAspect {

        @Autowired
        private HttpServletRequest httpServletRequest;

        // Generic performance logger for any mothod
        private Object logPerfomanceInfo(ProceedingJoinPoint joinPoint, String remoteAddress) {
            StringBuilder tag = new StringBuilder();
            if (joinPoint.getTarget() != null) {
                tag.append(joinPoint.getTarget().getClass().getName());
                tag.append(".");
            }
            tag.append(joinPoint.getSignature().getName());
            StopWatch stopWatch = new StopWatch(tag.toString());
            Object result = joinPoint.proceed(); // continue on the intercepted method
            stopWatch.stop();

            PerformanceUtils.logInPerf4jFormat(stopWatch.getStartTime(), stopWatch.getElapsedTime(), stopWatch.getTag(), stopWatch.getMessage(), remoteAddress);
            return result;
        }

        @Around("execution(* $$$.$$$.$$$.api.controller.*.*(..))")
        public Object logAroundApis(ProceedingJoinPoint joinPoint) throws Throwable {
            String remoteAddress = null;
            if (httpServletRequest != null) {
               remoteAddress = httpServletRequest.getRemoteAddr();
            }
            return logPerfomanceInfo(joinPoint, remoteAddress);
        }

        @Around("execution(* $$$.$$$.$$$.$$$.$$$.$$$.*(..))")
        public Object logAroundService(ProceedingJoinPoint joinPoint) throws Throwable {
            String remoteAddress = null;
            if (httpServletRequest != null) {
                remoteAddress = httpServletRequest.getRemoteAddr();
            }
            return logPerfomanceInfo(joinPoint, remoteAddress);
        }

我没有收到任何编译时错误，但是当我启动我的码头服务器时，我执行以下异常：

嵌套的异常是 java.lang.IllegalStateException：未找到线程绑定请求：您指的是实际 Web 请求之外的请求属性，还是在原始接收线程之外处理请求？如果您实际上在 Web 请求中操作并且仍然收到此消息，则您的代码可能在 DispatcherServlet/DispatcherPortlet 之外运行：在这种情况下，请使用 RequestContextListener 或 RequestContextFilter 来公开当前请求。

这里需要注意的一件事是，如果我删除“logAroundService”方法，我不会得到任何异常。

答案 1

您不应该在您的方面自动连接 a，因为这会将您的方面绑定为仅对从执行中调用的类运行。HttpServletRequestHttpServletRequest

而是在需要时使用以获取请求。RequestContextHolder

private String getRemoteAddress() {
    RequestAttributes attribs = RequestContextHolder.getRequestAttributes();
    if (attribs instanceof NativeWebRequest) {
        HttpServletRequest request = (HttpServletRequest) ((NativeWebRequest) attribs).getNativeRequest();
        return request.getRemoteAddr();
    }
    return null;
}

答案 2

@M.Deinum的答案对我不起作用。我改用这些代码

RequestAttributes attribs = RequestContextHolder.getRequestAttributes();
if (RequestContextHolder.getRequestAttributes() != null) {
    HttpServletRequest request = ((ServletRequestAttributes) attributes).getRequest();
    return request.getRemoteAddr();
}
