我是靠谱客的博主殷勤黑裤，最近开发中收集的这篇文章主要介绍说说guice的异常，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

guice的异常我觉得很烂，居然把我的异常吃掉了没有打印出来。

@Singleton
public class ProxyRoutineInit {

	private final ScheduledExecutorService scheduler =
			Executors.newScheduledThreadPool(2, new NamedThreadFactory("ProxyRoutineInit"));

	@Inject
	private SupplierManager supplierManager;

	@Inject
	@Named("config.log.base.path")
	private String logBasePath;

	@Inject
	public void onInject() {
		scheduler.scheduleWithFixedDelay(new LogCleanTask(logBasePath), 3, 0, TimeUnit.HOURS);
		scheduler.scheduleWithFixedDelay(new FeedStatusResetTask(supplierManager), 10, 10, TimeUnit.SECONDS);
	}
}

PS:

好吧，不是guice的问题，是ScheduledThreadPoolExecutor太坑爹了。

    public ScheduledFuture<?> scheduleWithFixedDelay(Runnable command,
                                                     long initialDelay,
                                                     long delay,
                                                     TimeUnit unit) {
        if (command == null || unit == null)
            throw new NullPointerException();
        if (delay <= 0)
            throw new IllegalArgumentException();
        RunnableScheduledFuture<?> t = decorateTask(command,
            new ScheduledFutureTask<Boolean>(command,
                                             null,
                                             triggerTime(initialDelay, unit),
                                             unit.toNanos(-delay)));
        delayedExecute(t);
        return t;
    }
