InterruptedException：睡眠中断

标签： java singleton ejb interrupted-exception

我推迟了我的申请，有时我收到以下例外：

java.lang.InterruptedException: sleep interrupted

我一直在这个例外超过一个星期，仍然没有找到解决方案。我已阅读了很多论坛，然后提到我需要做以下事情：

  • 抛出RuntimeException
  • Thread.currentThread（）。interrupt（）通过恢复线程的状态

问题是只有在Glassfish中执行以下操作后才会出现此异常：

[#|2014-05-16T17:24:15.881+0100|WARNING|oracle-glassfish3.1.2|com.sun.grizzly.config.GrizzlyServiceListener|_ThreadID=13;_ThreadName=Thread-2;|GRIZZLY0023: Interrupting idle Thread: admin-thread-pool-4848(2).|#]

程序中只有一个Thread，程序需要继续执行。以下是代码：

@Startup
@Singleton
public class Listener {

    @PostConstruct
    public void init() {
        while(true) {
            try {
                Thread.sleep(TimeUnit.SECONDS.toMillis(1000));
                // there are other codes that insert to the database and get information back from the database
            }
            catch(InterruptedException e) {
                e.printStackTrace();
                if(Thread.currentThread().isInterrupted()) {
                    Thread.currentThread().interrupt(); // restore interuppted status
                }
            }
        }
    }
}

这是我从stacktrace得到的：

有什么想法吗？

答案 0 :(得分：0)

这对我来说很糟糕。 @PostConstruct中有一个无限循环。对我来说，这说明你的容器永远无法启动，因为Listener从未完成它的构建阶段。

你确定你不想在一个单独的线程上做这项工作（无限循环）吗？也许您想使用ScheduledExecutorService

例如：

@Inject ScheduledExecutorService executor;

@PostConstruct
void init() {
    Runnable runnable = new Runnable() {
        public void run() {
            doSomeStuffInTheDatabase();
        }
    };
    long delaySeconds = 1;
    long periodSeconds = 1;
    executor.scheduleAtFixedRate(runnable, delaySeconds, periodSeconds, TimeUnit.SECONDS);
}
