 <version>4.0.0-alpha-2</version>
</dependency>
<dependency>
 <groupId>org.seleniumhq.selenium</groupId>

写hellowolrd类

 public static void loginYY( String username,String password){
 System.setProperty("webdriver.chrome.driver", "F://wb//chromedriver.exe");
 ChromeOptions options = new ChromeOptions();
 ChromeDriver webDriver = new ChromeDriver(options);
 String url = "";
 webDriver.get(url); //
 // 与浏览器同步非常重要，必须等待浏览器加载完毕
 webDriver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
 
 //找到登陆按钮 并点击
 webDriver.findElement(By.xpath("//a[@class='w-head__main__cnt__right__item__tl__t wHead__login__btn']")).click();
 //找到账号密码登陆 并点击
 webDriver.findElement(By.xpath("//a[@id='back2Commonlogin-btn']")).click();
 
 //找到内部 iframe 
 WebElement iframe = webDriver.findElement(By.className("udbsdk_frm"));
 webDriver.switchTo().frame(iframe);
 
 //设置账号
 webDriver.findElement(By.xpath("//input[@class='placeholder E_acct']")).sendKeys(username);
 webDriver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
 //设置密码
 webDriver.findElement(By.xpath("//input[@class='placeholder E_passwd']")).sendKeys(password);
 webDriver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
 List<WebElement> elements= webDriver.findElements(By.xpath("//div[@class='form_item form_opra']/a[@class='m_button_large E_login']"));
 for(WebElement w:elements){
 if(w.getText().equals("登录")){
 //点击登陆按钮
 w.click();
 }
 }
 }
 

功能完成 试验效果
