public class ChromeDriverConf {

}

application.yml配置：

server:
  port: 8055
chromedriver:
  driverPath: C:/softs/chromedriver.exe
  chromePath: C:/softs/chrome/chrome.exe
  picSavePath: D:/imgupload/

问题解决：

1.NoSuchMethodError for com.google.common.base.Preconditions.checkState

2.在centos部署时可能会出现的问题，杜绝方法：

1.chrome和chromedriver版本对应

使用Selenium时,如何选择ChromeDriver驱动版本对应Chrome浏览器版本

2.root权限打开chrome浏览器

需要加配置项

//          -–no-sandbox”参数是让Chrome在root权限下跑
            chromeOptions.addArguments("--no-sandbox");

3.同时设置chrome和chromedriver的地址：

System.setProperty("webdriver.chrome.driver", driverPath);
            ChromeOptions chromeOptions = new ChromeOptions();
            chromeOptions.setBinary(chromePath);
