JDBC8.011连接数据库 3个小改动

//注册驱动

8.0

DriverManager.registerDriver(new com.mysql.cj.jdbc.Driver());

5.5

DriverManager.registerDriver(new com.mysql.jdbc.Driver());

mysql8.0和之前版本的区别,首先驱动换了,不是com.mysql.jdbc.Driver而'com.mysql.cj.jdbc.Driver'.

连接数据库地址有变化

mysql8.0是不需要建立ssl连接的,你需要显示关闭,即url中的&useSSL=false;

java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.

此错误代码需要通过配置serverTimezone配置属性  &serverTimezone=Hongkong

主要就这几个问题

8.0

Url="jdbc:mysql://localhost:3306/db3?useSSL=false&serverTimezone=Hongkong&characterEncoding=utf-8&

autoReconnect=true";

连接地址+ssl连接关闭+时区为hk+字符集为utf-8+数据库自动连接
