jdbc编译报错，数据库链接是否写对？

Connection conn = DriverManager.getConnection(

"jdbc:mysql://usr/local/mysql-8.0.25-macos11-x86_64/data/jt_db?characterEncoding=utf-8",

"root",

"00000000");

return conn;

检查下mysql服务是否已经启动，第二个连接串改成这个样子:

jdbc:mysql://localhost:3306/jt_db?useUnicode=true&characterEncoding=gbk&autoReconnect=true&failOverReadOnly=false
