记录Java ShutdownHook

public class TestMe {

	static boolean isNornamExit = true;

	private static final void shutdownCallback() {

		if (!isNornamExit) {
			System.out.println("exception.");
		} else {
			System.out.println("exit normally.");
		}

	}

	public static void main(String[] args) throws InterruptedException {

		Runtime.getRuntime().addShutdownHook(new Thread() {
			@Override
			public void run() {
				shutdownCallback();

			}
		});

		isNornamExit = false;
		System.exit(1);

	}

}

 

注意正常退出也会执行 shutdownCallback()方法，所以要有标识存储是否正常退出信息，然后根据标识决定hook 方法怎么实现。
