Java多线程

• 无返回值

        new Thread(() -> {
            try {
                reportManageService.createMsg(reportDto);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }).start();

• 有返回值(get获取返回值会阻塞)

		FutureTask futureTask = new FutureTask(() -> reportManageService.createMsg(reportDto));
        new Thread(futureTask).start();
        Object res = futureTask.get(3, TimeUnit.SECONDS);
        if (null!=res){
            log.info((String) futureTask.get()+"-------------------------------------------------------------------------");
            return (Result
