Answer 1

你的基本例外是......

java.lang.reflect.InvocationTargetException

InvocationTargetException是一个已检查的异常，它包装了由调用的方法或构造函数抛出的异常。通过反射调用方法是一个额外的抽象级别。反射层将任何异常包装在InvocationTargetException. 在构造时提供并通过getTargetException()方法访问的“目标异常”现在称为原因，可以通过Throwable.getCause()方法访问，以及前面提到的“遗留方法”。

解决方案

最好的方法是在 中解开原因InvocationTargetException以获取原始异常。

try {

        System.setProperty("webdriver.chrome.driver","D:\\Automation\\chromedriver_win32\\chromedriver.exe");
        WebDriver driver=new ChromeDriver();

} catch (InvocationTargetException e) {
        // the real cause
        e.getCause().printStackTrace();
        
} catch (Exception e) {
        // generic exception handling
        e.printStackTrace();
}

最佳实践

根据最佳实践，请遵循以下准则：

• 将ChromeDriver升级到当前的ChromeDriver v96.0级别。
• Chrome已更新为当前的 _chrome=96.0.4664.45。（根据chrome=96.0.4664.45 发行说明）。
