com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to

折腾了好久，后来发现是版本问题，驱动和数据库不匹配导致。原来用的是5.1.37的驱动。数据库是mysql5.7，可以连接成功。就在我把数据库换成了8.0之后，所有的买点啥都报标题里的错误了。换成了下边这个驱动就OK了。解决方法:在pom.xml里面重新添加<groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.13&l
