SpringApplication.run(ZhiHuiTreeApplication.class, args);
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("headless", "no-sandbox", "window-size=1200x800");
        WebDriver webDriver = new RemoteWebDriver(new URL("http://127.0.0.1:4445"), chromeOptions);
        webDriver.get("https://www.baidu.com/");
        Thread.sleep(2000);
        WebElement element = webDriver.findElement(By.xpath("//*[@id="tsf"]/div[2]/div[1]/div[3]/center/input[1]"));
        System.out.println(element.getText());
        webDriver.quit();
