For example, video encoding and decoding are time-consuming operations. The more thread tasks, the more time spent in task switching. The number of threads should be reduced. CPU-intensiveThe number of task threads should be equal to the number of cores of the CPU.IO intensiveIO-intensive CPU consumption is relatively small, and most of the time is waiting for IO. The more threads, the higher the efficiency, but there are limitations. Our general applications belong to this category. The number of core threads = the number of CPU cores * 2.*/}public WSListener() {}public void business(String aa,String bb) {// must not block heremsgTaskService.execute(() -> {// handle businesslogger.info("Thread pool thread"+Thread.currentThread().getId());} catch (JSONException e) {logger.info(Thread.currentThread().getId()+" - Thread JSONException - [Error] "+e);throw new RuntimeException(e);}});}}
