windows环境下Java连接mysql遇到的一些问题

• 错误信息：java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
• 解决方法：在连接数据库的url后面加上 serverTimezone=UTC， 如果有多个选项，中间使用&分开
• 错误信息：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.
  java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
• 解决方法：在连接数据库的url中添加characterEncoding=utf8&useSSL=false， 若有其它选项，中间使用&断开

最后的ulr是这样

"jdbc:mysql://localhost:3306/supermarket?characterEncoding=utf8&useSSL=false&serverTimezone=UTC"

我的数据库名字为supermarket
