Answer 1

确保您已正确添加独立的jar在您的项目中。你可以从seleniumhq的官方网站下载它。 java -jar selenium-server-standalone-x.xx.x.jar

如果您已成功地将罐子，试试下面的代码：

`

public class Google { 

    public static void main(String[] args) throws InterruptedException { 
     System.setProperty("webdriver.chrome.driver","***location of your chromedriver.exe***"); 
     WebDriver driver = new ChromeDriver(); 
     driver.manage().window().maximize(); 
     driver.get("https://www.google.com/"); 
     driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
