实例代码

• 按照默认配置启动chrome 

public static void main(String[] args) {
        String chromebin = "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe";//chrome启动文件路径
        String chromedriver = "E:/**/**/**/chromedriver.exe";//chromedriver文件路径
    
        /* 设定 chrome启动文件的位置, 若未设定则取默认安装目录的 chrome */
        System.setProperty("webdriver.chrome.bin", chromebin);
        /* 设定 chrome webdirver 的位置 ,若未设定则从path变量读取*/
        System.setProperty("webdriver.chrome.driver", chromedriver);
        
        WebDriver driver = new ChromeDriver();
        driver.get("http://www.baidu.com");

        driver.close();//关闭浏览器
        driver.quit();//退出浏览器

}

• 使用服务管理chrome

public static void main(String[] args) {
        String chromedriver = "E:/**/**/**/chromedriver.exe";
    
        ChromeDriverService service = new ChromeDriverService.Builder()
                                        .usingDriverExecutable(new File(chromedriver))
                                        .usingAnyFreePort().build();    
        WebDriver driver = new ChromeDriver(service);
        driver.get("http://www.baidu.com");
        driver.quit();
    }

• 自定义配置启动chrome 

import java.io.File;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

public class test {
    public static void main(String[] args) {
        String chromebin = "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe";
        String chromedriver = "E:/**/**/**/chromedriver.exe";
    
        /* 设定 chrome启动文件的位置, 若未设定则取默认安装目录的 chrome */
        System.setProperty("webdriver.chrome.bin", chromebin);
        /* 设定 chrome webdirver 的位置 ,若未设定则从path变量读取*/
        System.setProperty("webdriver.chrome.driver", chromedriver);
        
        WebDriver driver = new ChromeDriver(setChromeOptions());
        driver.get("http://www.baidu.com");
        driver.close();//关闭浏览器
        driver.quit();//退出浏览器
   }

/**
     * 设置 Chrome 浏览器的启动配置
     * @return ChromeOptions Chrome 参数设置
     */
    public static ChromeOptions setChromeOptions(){
        ChromeOptions options = new ChromeOptions();
        /*
         * 设置参数
         * --start-maximized 浏览器最大化
         * test-type 忽略认证错误警示--ignore-certificate-errors
         * */
        options.addArguments("--start-maximized");
        options.addArguments("test-type");
        
        /*
         * 加载插件
         * files\youtube.crx 代表查件文件路径
         * */
         File file = new File ("files\youtube.crx");
         options.addExtensions(file);

        return options;
    }
}

• 自定义配置，使用服务启动chrome 

import java.io.File;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeDriverService;
import org.openqa.selenium.chrome.ChromeOptions;

public class test {

    public static void main(String[] args) {
        String chromedriver = "E:/**/**/**/chromedriver.exe";
    
        ChromeDriverService service = new ChromeDriverService.Builder()
                                        .usingDriverExecutable(new File(chromedriver))
                                        .usingAnyFreePort().build(); 
        WebDriver driver = new ChromeDriver(service,setChromeOptions());
        driver.get("http://www.baidu.com");
        driver.quit();
    }
    
    /**
     * 设置 Chrome 浏览器的启动配置
     * @return ChromeOptions Chrome 参数设置
     */
    public static ChromeOptions setChromeOptions(){
        ChromeOptions options = new ChromeOptions();
        /*
         * 设置参数
         * --start-maximized 浏览器最大化
         * test-type 忽略认证错误警示--ignore-certificate-errors
         * */
        options.addArguments("--start-maximized");
        options.addArguments("test-type");
        
        /*
         * 加载插件
         * files\youtube.crx 代表查件文件路径
         * */
         File file = new File ("files\youtube.crx");
         options.addExtensions(file);

        return options;
    }    
}

注意：为避免路径问题，chrome浏览器建议安装在默认路径下
