shutdown.java
// 推荐做法：
static class Stop extends Thread {
static void init() {
Runtime.getRuntime().addShutdownHook(new Stop());
}
@Override
public void run() {
Thread.currentThread().setName("stop");
App.stop();
Thread.getAllStackTraces().forEach((k, v) -> {logger.debug("剩余线程: {}, {}", k, v);});
}
}
// 加上信号处理的版本(不建议使用信号处理，Signal是Sun的内部API而且会让程序对系统类型有依赖)：
static class Stop extends Thread implements SignalHandler {
static void init() {
Stop appStop = new Stop();
Signal.handle(new Signal("INT"), appStop);
Signal.handle(new Signal("TERM"), appStop);
}
@Override
public void handle(Signal signal) {
logger.debug("收到信号: {}", signal.toString());
Runtime.getRuntime().addShutdownHook(this);
System.exit(0);
}
@Override
public void run() {
Thread.currentThread().setName("stop");
App.stop();
Thread.getAllStackTraces().forEach((k, v) -> {logger.debug("剩余线程: {}, {}", k, v);});
}
}
