这是我的hibernate配置xml文件，我已经设置了usessl=false，但仍然收到警告：

警告：不建议在没有服务器身份验证的情况下建立SSL连接。根据MySQL 5.5.45+、5.6.26+和5.7.6+的要求，如果未设置显式选项，默认情况下必须建立SSL连接。为了符合不使用SSL的现有应用程序，verifyServerCertificate属性设置为'false'。您需要通过设置usessl=false来显式禁用SSL，或者设置usessl=true并为服务器证书验证提供truststore。

即使我遇到同样的错误，问题是sql-connector版本和MySql80实例不匹配，当我将connector版本更新到8.0.21时，问题就解决了...
