调用driver.quit()出现java.net.SocketException: Connection reset的解决办法

爬取流程完全正常，能成功获取网站响应与内容，但调用driver.quit();或driver.close();时会抛出java.net.SocketException: Connection reset异常，不调用.quit();则无异常。已查阅相关Stack Overflow线程但未找到解决方法。

核心代码 #

String url = "https://relatedwords.org/relatedto/";
System.setProperty("webdriver.chrome.driver", filePath);

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");

WebDriver driver = new ChromeDriver(chromeOptions);
driver.get(url + "Fishsticks");

WebElement words = driver.findElement(By.className("words"));
final List<WebElement> wordList = words.findElements(By.tagName("a"));
wordList.forEach(word -> System.out.println(word.getText()));

// 去掉这行就不会抛出异常
driver.quit();

环境信息 #

• Chrome版本：109.0.5414.120（无更新）
• ChromeDriver版本：109.0.5414.74
• Selenium版本：4.8.0

解决方案 #

1. 匹配Chrome与ChromeDriver的精确版本 #

当前Chrome版本为109.0.5414.120，但ChromeDriver用的是109.0.5414.74，版本号后缀不一致会导致通信异常。下载与Chrome完全匹配版本的ChromeDriver替换现有文件即可。

2. 添加ChromeOptions参数优化配置 #

在初始化ChromeOptions时添加以下参数，避免WebSocket连接异常：

chromeOptions.addArguments("--remote-debugging-port=9222");
chromeOptions.addArguments("--disable-dev-shm-usage");
chromeOptions.addArguments("--no-sandbox");
chromeOptions.addArguments("--disable-gpu"); // 无头模式下推荐添加

3. 使用Selenium 4内置的驱动管理 #

放弃手动设置System.setProperty，改用WebDriverManager自动管理驱动版本，确保驱动与浏览器版本匹配：

// 需先引入WebDriverManager依赖
WebDriverManager.chromedriver().setup();

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");

WebDriver driver = new ChromeDriver(chromeOptions);

4. 临时捕获异常（不推荐长期使用） #

如果以上方法暂时无法生效，可以捕获driver.quit()时的异常，避免程序中断：

try {
    driver.quit();
} catch (Exception e) {
    // 忽略Connection reset异常
}

5. 检查网络环境 #

确认本地防火墙、代理软件没有拦截ChromeDriver与Chrome之间的WebSocket连接，同时检查本地9222等调试端口是否被其他程序占用。
