SSM jdbc报错 Cannot create PoolableConnectionFactory

Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: 
Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException:
 Cannot create PoolableConnectionFactory 
 (The server time zone value '�й���׼ʱ��' 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.)

无法解析时区，在URL后追加上serverTimezone=UTC
