VPS启动ChromeDriver成功但遇CDP版本匹配警告，请求技术支持

在VPS上成功启动ChromeDriver后，执行java -jar demo.jar时出现两类警告，具体输出如下：

$ java -jar demo.jar

SLF4J: Defaulting to no-operation (NOP) logger implementation

1. SLF4J警告处理 #

该警告是因为项目仅引入了SLF4J日志门面，缺少具体的日志实现依赖。需添加对应日志框架依赖：

• Maven：在pom.xml中添加Logback实现（常用选项）

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.4.8</version> <!-- 版本可按需调整 -->
</dependency>

• Gradle：在build.gradle中添加

implementation 'ch.qos.logback:logback-classic:1.4.8'

重新打包demo.jar后运行，警告即可消除。

2. CDP版本不匹配警告处理 #

警告提示找不到与ChromeDriver 111匹配的CDP（Chrome DevTools Protocol）实现，需添加对应版本的Selenium DevTools依赖：

1. 确认项目中Selenium核心依赖的版本（比如示例中的4.8.1）
2. 添加对应v111版本的DevTools依赖，版本号需与Selenium核心版本完全一致：

• Maven

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-devtools-v111</artifactId>
    <version>4.8.1</version>
</dependency>

• Gradle

implementation 'org.seleniumhq.selenium:selenium-devtools-v111:4.8.1'

重新打包后，CDP相关警告会消失。
