现象

接收request请求，第一次获取到了param，第二次获取不到

原因

第一次接受到request之后，把request存储在

TransmittableThreadLocal<HttpServletRequest> REQUEST_THREAD_LOCAL = new TransmittableThreadLocal<>()

当中以便给异步线程使用，由于controller线程exe1已经执行完成了，但是controller创建的子线程还没有执行完但是占用着request，导致request中有个属性状态值没有改变，后面新的请求又使用了同个线程exe1，导致request不会赋值新的param

解决方案

controller起子线程使用如下方式，使用完关闭线程池

        ServletRequestAttributes attributes = (ServletRequestAttributes)       
        RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        RequestUtil.shareRequest(request);
        ExecutorService executorService = ThreadUtil.newExecutor(10 ,10);
        // 如果没有使用Ttl线程来处理，会有线程安全问题，并发量大会出现获取不到数据的情况
        ExecutorService ttlExecutorService = TtlExecutors.getTtlExecutorService(executorService);
        try {
            CompletableFuture<String> completableFuture = CompletableFuture.supplyAsync(() -> {
                try {
                    Thread.sleep(10000);
                } catch (InterruptedException e) {
                    throw new RuntimeException(e);
                }
                String token = userInfoManager.getToken();
                if (token == null) {
                    logger.info("test1 token is null");
                }
                return "yes";
            }, ttlExecutorService);
            CompletableFuture.allOf(new CompletableFuture[]{completableFuture}).join();
            String result = null;
            try {
                result = completableFuture.get();
                logger.info("result:{}", result);
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        } finally {
            RequestUtil.removeShareRequest();
            ttlExecutorService.shutdown();
        }
