[Selenium] Java代码获取，设置屏幕分辨率

import java.awt.Dimension;
import java.awt.DisplayMode;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Insets;
import java.awt.Rectangle;
import java.awt.Toolkit;

public Rectangle getDestktopRectangle(){
	Rectangle windowSize = new Rectangle();
	Dimension scrSize = Toolkit.getDefaultToolkit().getScreenSize();
	Insets scrInsets = Toolkit.getDefaultToolkit().getScreenInsets(GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getDefaultConfiguration());

	//获取屏幕可以利用的width和height
	//windowSize.setBounds(scrInsets.left, scrInsets.top, scrSize.width - scrInsets.left - scrInsets.right, scrSize.height - scrInsets.top - scrInsets.bottom);

	//获取屏幕的分辨率
	windowSize.setBounds(scrInsets.left, scrInsets.top, scrSize.width, scrSize.height);
	logger.info("The desktop resolution is : " + windowSize);
	return windowSize;
}

public void setDestktopRectangle(int width, int height){
	GraphicsEnvironment environment = GraphicsEnvironment.getLocalGraphicsEnvironment();
	GraphicsDevice device=environment.getDefaultScreenDevice(); 

	//取得所支持的分辨率
	DisplayMode[] displayModes= device.getDisplayModes();
	for(DisplayMode displayMode : displayModes){
		logger.info("Available display mode : ["+displayMode.getWidth()+" , "+displayMode.getHeight()+" , "+displayMode.getBitDepth()+" , "+displayMode.getRefreshRate()+"]");
	}

	//new DisplayMode(分辨率宽,分辨率高,颜色位数,刷新率)
	DisplayMode displayMode=new DisplayMode(width,height,16,75);
	device.setDisplayMode(displayMode);
}

设置屏幕分辨率不一定好使。
