springMvc异步处理请求

方式一

    @GetMapping("/test")
    public WebAsyncTask<CommonResult> test() throws Exception {
        log.info("主线程开始");
        Callable<CommonResult> result = (() -> {
            log.info("副线程开始");
            Thread.sleep(10000);
            log.info("副线程结束");
            return CommonResult.success(null,"success");
        });  //直接Callable也可以，但是不能设置超时时间和超时回调以及成功回调
        WebAsyncTask<CommonResult> webAsyncTask = new WebAsyncTask<>(300000, result);
        webAsyncTask.onTimeout(timeOutCallBack());
        log.info("主线程结束");
        return webAsyncTask;
    }

    /**
     * 超时回调
     */
    private Callable<CommonResult> timeOutCallBack(){
        Callable<CommonResult> callback = (()-> {
            log.info("请求超时");
            return CommonResult.failed("请求超时");
        });
        return callback;
    }
