獲取設備相關信息工具包

拿走不謝
在使用springboot獲取屏幕參數時，可能會報關於headless爲NULL的錯誤，不要慌，這樣來：只需要在啓動的application中替換main函數內容爲：

@SpringBootApplication
public class AdApplication{
    public static void main(String[] args) {
        new SpringApplicationBuilder(AdApplication.class).headless(false).run(args);
    }
}

如果這樣紙還沒有解決你的問題，那麼參考大神回覆！
