Java org.openqa.selenium.NoSuchSessionException:没有这样的会话

在selenium中访问下面的方法时获取“无此类会话”异常。我知道网上有很多相同的问题和不同的答案，但在我的案例中似乎没有一个得到解决。有什么帮助吗

Chrome驱动程序版本：-2.38 铬合金版本：-66.0.3359.117

例外消息是：-

我的节目：-

 else if (CommonObjRepository.getMessage().contentEquals("Login")) {


// This is where exception is being thrown //
            String Message = wait
                    .until(ExpectedConditions
                            .visibilityOfElementLocated(By.xpath("html/body/div[1]/div/div/div[2]/div/div[2]/div/div/p")))
                    .getText();

            assertEquals(ReadProperties.GetConstant("XXTTX"), Message);
            CommonObjRepository.getLog().info("***** XXXYYYZZZ *****");

        }

此错误消息

org.openqa.selenium.NoSuchSessionException: no such session

…表示chromedriver=2.38无法启动与WebClient（即Chrome浏览器）的活动会话

您的主要问题是所使用的二进制文件之间的版本兼容性，如下所示：

• 尽管您使用的是最新的Selenium客户端版本3.11.0、Chrome驱动程序版本2.38和Chrome版本v66.0
• 您的JDK版本是1.8.0_144，非常古老

---

解决方案

• 将JDK升级到最新级别
• 通过IDE清理项目工作区，并仅使用所需的依赖项重建项目
• 如果您的基本Web客户端版本太旧，请卸载它并安装最新的GA和Web客户端发布版本
• 重新启动系统
• 执行
