解决javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validati-优快云博客

文章描述了一次测试过程中遇到的SSL连接问题，原因是服务器SSL证书过期。开发者通过分析错误信息和浏览器警告，识别出问题并建议运维人员介入。这表明虽然运维通常负责此类问题，但在实际项目中，研发和测试也可能首先遇到这类技术问题。

今天测试小伙突然让我看一个异常，已经运行了很久的系统突然发现报错了，我抓下了错误信息，如下：

看了下方法，就是请求第三方系统获取token，直接猜测是SSL证书的问题，在浏览器里直接访问第三方接口地址，结果浏览器已经提示不安全了，附下图：
