Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class
is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SP
I and manual loading of the driver class is generally unnecessary.
//除非顯示說明useSSL=false
Fri Mar 17 15:27:15 CST 2017 WARN: Establishing SSL connection without server's
identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ an
d 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 ve
rifyServerCertificate property is set to 'false'. You need either to explicitly
disable SSL by setting useSSL=false, or set useSSL=true and provide truststore f
or server certificate verification.
//通過url後面加上?serverTimezone=UTC解決
java.sql.SQLException: The server time zone value '?й???????' is unrecognized o
r represents more than one time zone. You must configure either the server or JD
BC driver (via the serverTimezone configuration property) to use a more specifc
time zone value if you want to utilize time zone support.
