提问 项目 BI智能平台，想用定时任务重新分析失败的分析任务， 大致思路：是把controller层的线程池异步调用ai的代码抽成一个方法，供接口和定时任务共用，定时任务每隔一段时间通过chartService获取失败任务列表并遍历，遍历中调用controller层的异步调用ai的方法。 现在出现问题，定时任务在调用controller的异步调用ai的方法时，会报错。 报错信息：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: In this case, use RequestContextListener or RequestContextFilter to expose the current request. 是什么原因照成的问题和如何解决，请大神指教！ ==================定时任务代码===================== @Component public class FailedGenChartWrokSchedule { private static ChartController chartController; @Autowired private void setChartController(ChartController chartController) { FailedGenChartWrokSchedule.chartController = chartController; } @Resource private ChartService chartService; @Scheduled(fixedRate = 50000) public void doFailedWrok(){ log.info("失败任务重启策略启动"); QueryWrapper<Chart> wrapper = new QueryWrapper<>(); wrapper.eq("status","failed"); List<Chart> chartList = chartService.list(wrapper); try { for (int i = 0; i < chartList.size(); i ) { Chart chart = chartList.get(i);

} } } =================原因及解决办法=============== 原因：项目中带的AuthInterceptor拦截器中调用RequestContextHolder.currentRequestAttributes(); ，定时任务没有RequestAttributes对象，所以异常了。 解决办法：在AuthInterceptor中的RequestContextHolder.currentRequestAttributes();时捕捉异常。 参考代码： public Object doInterceptor(ProceedingJoinPoint point) throws Throwable { // 计时 StopWatch stopWatch = new StopWatch(); stopWatch.start(); // 获取请求路径 RequestAttributes requestAttributes = getRequestAttributesSafely(); // 生成请求唯一 id String requestId = UUID.randomUUID().toString(); String url = ""; String remoteHost = ""; if (requestAttributes != null) { HttpServletRequest httpServletRequest = ((ServletRequestAttributes) requestAttributes).getRequest(); url = httpServletRequest.getRequestURI(); remoteHost = httpServletRequest.getRemoteHost(); } // 获取请求参数 Object[] args = point.getArgs(); String reqParam = "[" StringUtils.join(args, ", ") "]"; // 输出请求日志 log.info("request start，id: {}, path: {}, ip: {}, params: {}", requestId, url, remoteHost, reqParam); // 执行原方法 Object result = point.proceed(); // 输出响应日志 stopWatch.stop(); long totalTimeMillis = stopWatch.getTotalTimeMillis(); log.info("request end, id: {}, cost: {}ms", requestId, totalTimeMillis); return result; } private RequestAttributes getRequestAttributesSafely() { RequestAttributes requestAttributes = null; try { requestAttributes = RequestContextHolder.currentRequestAttributes(); } catch (IllegalStateException e) { log.warn("未能获取到requestAttributes,本地调用"); } return requestAttributes; }
