抛出这个异常的原因是：
Thrown when code that is dependent on a keyboard, display, or mouse is called in an environment that does not support a keyboard, display, or mouse.
通常就是把程序丢到服务器（服务器上可能没有安装键盘、鼠标、显示器之类）上可能导致这个错误。
建议服务器启动Java程序时增加 -Djava.awt.headless=falsh 选项，
如果上面选项不行，换成 -Djava.awt.headless=true 试试。

试了试，还是报 java.awt.HeadlessException 这个异常
