I used mysql 5.6 to connect to mysql using JDBC, but now it cannot be used. I am not clear about the reason and have found it online, but I cannot find a solution, connecting JAR package is mysql-connector-java-5.1.26-bin.jar, please know the great God to answer the younger brother

This is to use JDBC to connect to MYSQL

Import java. SQL .*;

Public class TestMysqlConnection {
Public static void main (String [] args ){
Connection conn = null;
Try {
Class. forName ("com. mysql. jdbc. Driver ");
Conn = DriverManager. getConnection ("jdbc: mysql: // localhost/bbs", "root", "82215378 ");
} Catch (ClassNotFoundException e ){
E. printStackTrace ();
} Catch (SQLException e ){
E. printStackTrace ();
} Finally {
Try {
If (conn! = Null ){
Conn. close ();
Conn = null;
}
} Catch (SQLException e ){
E. printStackTrace ();
}
}
}

The error is as follows:
