public static void main(String[] args) {
		String a = NetUtil.getLocalAddress().getHostName();
		String b = NetUtil.getLocalAddress().getHostAddress();

		String x = NetUtil.getHostName();
		String y = NetUtil.getLocalHost();

		System.out.println("a=" + a);
		System.out.println("b=" + b);
		System.out.println("x=" + x);
		System.out.println("y=" + y);
	}

上面这个例子. 我在 mac os 上面测试
结果如下:

a=xxx.local
b=172.30.60.29
x=null  //这个没问题么?
y=172.30.60.29
