eclipse理解mysql遇到的问题

1、步骤

1、创建mysqltest01 java文件
2、创建jdbc文件夹，导入mysql-connector-java-8.0.11.jar包
3、新建获取数据连接类
public class Dbutil {
private String dbUrl=“jdbc:mysql://localhost:3306/user?useSSL=true”;
private String dbUsername=“root”;
private String dbPassword=“123456”;
private String jdbcName=“com.mysql.cj.jdbc.Driver”;
//获取mysql连接
public Connection getCon() throws Exception{
Class.forName(jdbcName);
Connection con=DriverManager.getConnection(dbUrl, dbUsername, dbPassword);
return con;
}
//关闭mysql连接
public void closeCon(Connection con)throws Exception{
if(con!=null) {
con.close();
}
}
public static void main(String[] args) {
Dbutil dbUtil=new Dbutil();
try {
dbUtil.getCon();
System.out.println(“数据库连接成功！”);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println(“数据库连接失败！”);
}
}
}

2遇到的问题

连接时：
The server time zone value ‘Öйú±ê׼ʱ¼ä’ is unrecognized or represents more than one
解决方式：cmd 打开mysql
show variables like ‘%time_zone%’;
set global time_zone=’+8:00’

*Url中显示SSL等问题*
private String dbUrl="jdbc:mysql://localhost:3306/user?useSSL=true";
