生产线程池的定义与使用

定义线程池

@Slf4j
@Component
public class PalmThreadPool {
    public static int CORE_POOL_SIZE = 4;

    private final AtomicInteger atomicInteger = new AtomicInteger(1);

    /**
     * 线程池
     */
    public ScheduledThreadPoolExecutor poolExecutor = new ScheduledThreadPoolExecutor(CORE_POOL_SIZE, r -> {
        Thread thread = new Thread(r, "bbc-palm-" + atomicInteger.getAndIncrement());
        log.debug("Create thread {}", thread.getName());
        return thread;
    }, (r, e) -> log.error("thread pool rejected"));
}

使用线程池

 this.palmThreadPool.poolExecutor.schedule(() -> {
                Input input= new Input();
                studentService.add(input);
}, 0, TimeUnit.SECONDS);
