java Selenium 发送126邮件 解决element not visible

网上很多例子，但是到了最后一次发送邮件的时候出现 element not visible 错误，因为页面中有两个发送按钮，  几经周折， 终于搞定了。

import org.openqa.selenium.WebElement;

 static WebDriver driver = new ChromeDriver();

  login_126_email(); 
  send_126_email();
  //driver.close();  
 }

 

 public static void login_126_email() throws InterruptedException{
  System.setProperty("webdriver.chrome.driver",
    "D:\\install\\selenium\\chromedriver2.25_win32\\chromedriver.exe");

  driver.get("http://mail.126.com/");
  Thread.sleep(1000);//必须等

  //登录
  driver.switchTo().frame(0);
  driver.findElement(By.name("email")).clear();
  driver.findElement(By.name("email")).sendKeys("testselenium");

  driver.findElement(By.name("password")).clear();
  driver.findElement(By.name("password")).sendKeys("!@#$%^");
  driver.findElement(By.id("dologin")).click();
  Thread.sleep(1000);
 }

 public static void send_126_email() throws InterruptedException{
  //  写信
  WebElement xiexin_element = driver.findElement(By.xpath("//span[contains(.,'写 信')]"));
  xiexin_element.click();
  Thread.sleep(1000);

  WebElement shoujianren_element = driver.findElement(By.className("nui-editableAddr-ipt"));
  shoujianren_element.sendKeys("[e-mail]");

  //WebElement zhuti_element = driver.findElement(By.xpath("//input[@class='nui-ipt-input'][contains(@id,'_subjectInput')]"));//以下一个过滤提交爱哦即可
  WebElement zhuti_element = driver.findElement(By.xpath("//input[contains(@id,'_subjectInput')]"));
  zhuti_element.sendKeys("Selenium自动发送126邮件测试");

  WebElement youjianneirong_element = driver.switchTo().frame(driver.findElement(By.className("APP-editor-iframe"))).findElement(By.className("nui-scroll"));
  youjianneirong_element.sendKeys("你好！这里是测试邮件，请您忽略！ 谢谢！  发送邮箱内容。。。");
  driver.switchTo().defaultContent();

  Actions actions = new Actions(driver);
  List<WebElement>  spanss = driver.findElements(By.xpath("//span[contains(.,'发送')]"));//因为有两个发送按钮
  for (WebElement span : spanss){
   actions.moveToElement(span).click().build().perform();
  }

 

  //退出登录
  WebElement tuichu_element = driver.findElement(By.linkText("退出"));
  tuichu_element.click();

 }
