Java对信号的处理

package com.chzhao.SignalTest;

import sun.misc.*;

@SuppressWarnings("restriction")
public class TestSignal implements SignalHandler {

    public void handle(Signal arg0) {
        System.out.println(arg0.getName() + "is recevied.");
    }
}

package com.chzhao.SignalTest;

import sun.misc.*;

public class App {
    @SuppressWarnings("restriction")
    public static void main(String[] args) {
        TestSignal handler = new TestSignal();
        Signal.handle(new Signal("TERM"), handler);
        Signal.handle(new Signal("INT"), handler);
        Signal.handle(new Signal("USR1"), handler);
        Signal.handle(new Signal("USR2"), handler);
        for (;;) {
            System.out.println("do something");
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}
