tomcat启动时报以下ssl的连接错误，mysql版本为5.7.17，虽然系统可以使用，但是日志量太大，还是处理下，只需要修改mysql的连接格式：
url.db= “jdbc:mysql://localhost:3306/disis3?user=root&password=XXXXX&useUnicode=true&characterEncoding=utf-8”
改为：
url.db=“jdbc:mysql://localhost:3306/disis3?user=root&password=XXXXX&useUnicode=true&characterEncoding=utf-8&useSSL=false”
对比原来增加了： &useSSL=false

修改上述连接方式后，替换了mysql8.0的驱动，从mysql官网介绍，mysql8.0的驱动是兼容支持MySQL 5.5, 5.6, 5.7,8.0。

做了以上两个修改之后，重新启动tomcat，tomcat日志打印不再提示以下错误信息
