我正在做我的Web应用程序，并且一直工作到今天。我打开了电源，启动了服务器，现在除了收到Java中的页面不再起作用的事实外，还收到此错误。 我没有修改任何Java页面。只有一些jsp或html。 我也尝试重新启动Mysql，但没有改变：

Thu Jul 12 11:51:00 CEST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
