jdbc mysql 连接
jdk 1.8.0_101  jre 1.8.0_101  mysql 5.7.13  mysql-connector-java-6.0.6-bin.jar


环境变量classpath 中加入mysql-connector-java-6.0.6-bin.jar




driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/ANSHANSHIFAN"
//使用com.mysql.cj.jdbc.Driver
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.
//除非显示说明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.
//通过url后面加上?serverTimezone=UTC解决
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.



driver="com.mysql.cj.jdbc.Driver"

url="jdbc:mysql://localhost:3306/ANSHANSHIFAN?serverTimezone=UTC&&useSSL=false"
