Answer 1

我怀疑它无法启动chromedriver.exe。在这一行：

System.setProperty("webdriver.chrome.driver", "chromedriver.exe");

重点是告诉它确切位于 chromedriver.exe 的位置，包括完整路径。您可能需要将其更改为：

System.setProperty("webdriver.chrome.driver", "C:\My\Path\To\chromedriver.exe");

正如ChromeDriver documentation所说：

  

确保服务器可以位于PATH上，或通过webdriver.chrome.driver系统属性指定其位置。
