首先jdk的setExtendedState是有bug的，需要先重载JFrame的setExtendedState方法

    /**

     * Fix the bug "jframe undecorated cover taskbar when maximized". See:

     * http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4737788

     *

     * @param state

     */

    @Override

    public void setExtendedState(int state) {

        if ((state & java.awt.Frame.MAXIMIZED_BOTH) == java.awt.Frame.MAXIMIZED_BOTH) {

            Rectangle bounds = getGraphicsConfiguration().getBounds();

            Rectangle maxBounds = null;

            // Check to see if this is the 'primary' monitor

            // The primary monitor should have screen coordinates of (0,0)

            if (bounds.x == 0 && bounds.y == 0) {

                Insets screenInsets = getToolkit().getScreenInsets(getGraphicsConfiguration());

                maxBounds = new Rectangle(screenInsets.left, screenInsets.top, bounds.width - screenInsets.right - screenInsets.left

                        , bounds.height - screenInsets.bottom - screenInsets.top);

            } else {

                // Not the primary monitor, reset the maximized bounds...

                maxBounds = null;

            }

            super.setMaximizedBounds(maxBounds);

        }

        super.setExtendedState(state);

    }
