springboot整合selenium实现页面数据爬取，两个问题记录

1.控制台出现 Only local connections are allowed.的提示

这表示只允许本地访问，不允许远程访问

** 解决办法：**

系统属性添加参数

System.setProperty("webdriver.chrome.whitelistedIps", "");

重启系统之后，就会出现如下提示，可以允许远程访问

2.出现如下报错，表示无法跨域

解决办法：

ChromeOptions类添加允许跨域的参数，问题解决

ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("--remote-allow-origins=*");
