Spring Batch Java应用调用ChromeDriver.quit()触发SocketException警告

问题场景 #

在Spring Batch框架的Java应用中使用Selenium，调用ChromeDriver.quit()时会触发onError警告，抛出java.net.SocketException: Connection reset异常；调试模式下不会出现该问题。

原代码示例 #

System.setProperty("webdriver.chrome.driver", "src\\main\\resources\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless=new");
ChromeDriver chromeDriver = new ChromeDriver(options);
            
chromeDriver.get("https://www.google.com/");
//select web items, interact with them
chromeDriver.quit();

原因分析 #

该警告本质是：调用quit()时，ChromeDriver会直接终止Chrome浏览器进程并关闭自身服务，而Selenium底层通过Netty维护的WebSocket连接还未正常断开，客户端仍尝试向已关闭的连接发送请求，从而触发连接重置异常。调试模式下进程退出速度较慢，连接有足够时间正常关闭，因此不会出现该问题。

解决方案 #

1. 调整资源释放顺序 #

先关闭浏览器窗口，再停止驱动服务，最后调用quit()，确保连接正常断开：

System.setProperty("webdriver.chrome.driver", "src\\main\\resources\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless=new");
ChromeDriver chromeDriver = new ChromeDriver(options);
            
chromeDriver.get("https://www.google.com/");
// 业务逻辑处理

// 调整释放顺序
chromeDriver.close(); // 先关闭窗口
chromeDriver.getSession().getDriverService().stop(); // 停止驱动服务
chromeDriver.quit(); // 最后调用quit

2. 过滤特定日志警告 #

如果不需要关注该警告，可在日志配置（如logback.xml）中关闭对应日志输出：

<logger name="org.asynchttp.netty.handler.WebSocketHandler" level="OFF"/>

3. 手动管理ChromeDriver生命周期 #

使用ChromeDriverService手动控制驱动的启动和停止，确保资源正确释放：

ChromeDriverService service = new ChromeDriverService.Builder()
        .usingDriverExecutable(new File("src\\main\\resources\\chromedriver.exe"))
        .build();
service.start();

ChromeOptions options = new ChromeOptions();
options.addArguments("--headless=new");
ChromeDriver chromeDriver = new ChromeDriver(service, options);
            
chromeDriver.get("https://www.google.com/");
// 业务逻辑处理

// 释放资源
chromeDriver.quit();
service.stop();

4. 确保Chrome与ChromeDriver版本匹配 #

版本不兼容可能导致进程异常退出，需保证Chrome浏览器和ChromeDriver的主版本号完全一致，避免因版本差异引发的连接问题。
