java.lang.IllegalStateException:找不到线程绑定的请求，方面是异常 [英] java.lang.IllegalStateException: No thread-bound request found, exception in aspect

问题描述

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，但是在启动码头服务器时出现以下异常:

I do not get any compile time errors but I do following exception when I start my jetty server:

嵌套的异常是java.lang.IllegalStateException:没有线程绑定 找到请求:您是指请求属性之外的 实际的Web请求，或处理原始请求之外的请求 接收线程?如果您实际上是在网络请求中进行操作 仍然收到此消息，则您的代码可能正在外部运行 的DispatcherServlet/DispatcherPortlet:在这种情况下，请使用 RequestContextListener或RequestContextFilter公开当前 请求.

nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

这里要注意的一件事是，如果删除"logAroundService"方法，则不会获得任何异常.

One thing to note here is, if I remove "logAroundService" method, I do not get any exceptions.

推荐答案

您不应在方面自动连接HttpServletRequest，因为这会将您的方面与只能在执行中的.

You shouldn't autowire a HttpServletRequest in your aspect as this will tie your aspect to be only runnable for classes that are called from within an executing HttpServletRequest.

在需要时使用RequestContextHolder获取请求.

Instead use the RequestContextHolder to get the request when you need one.

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