Stopper的使用

工具类,抽象死循环逻辑的

import java.util.concurrent.atomic.AtomicBoolean;

/**
 *  if the process closes, a signal is placed as true, and all threads get this flag to stop working
 */
public class Stopper {

	private static AtomicBoolean signal = new AtomicBoolean(false);
	
	public static final boolean isStopped(){
		return signal.get();
	}
	
	public static final boolean isRunning(){
		return !signal.get();
	}
	
	public static final void stop(){
		signal.set(true);
	}
}

使用

while (Stopper.isRunning()) {
            InterProcessMutex mutex = null;
            try {
                if (zkClient.getZkClient().getState() == CuratorFrameworkState.STARTED) {
                    mutex = zkClient.blockAcquireMutex();
                    // zk获取到锁开始执行业务逻辑,此处可以使用Thread.yield代理Thread.sleep方法
                }
            } catch (Exception ex) {
                logger.error("master scheduler thread error", ex);
            } finally {
                zkClient.releaseMutex(mutex);
            }
        }
