Cannot create PoolableConnectionFactory (The server time zone value '???��������??��??' 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.)

出现这个问题的原因是时间无法识别，只需要在连接mysql的url后添加：?serverTimezone=UTC即可

如：jdbc:mysql://localhost:3306/test?serverTimezone=UTC  #在数据库地址后边添加
