2.創(chuàng)建jdbc連接信息

variable name for created pool：鏈接變量名
databaseurl： jdbc:mysql://數(shù)據(jù)庫(kù)ip:端口/數(shù)據(jù)庫(kù)名?serverTimezone=UTC（貌似是數(shù)據(jù)庫(kù)時(shí)區(qū)設(shè)置問題）
serverTimezone=UTC為解決：
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.)
