尝试一下:

package dvddblibrary;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DBConnect {
    public static void main(String[] args) {
        try {
            String host = "xxx";
            String uName = "xxx";
            String uPass = "xxx";
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection(host, uName, uPass);
        } catch (SQLException err) {
            System.out.println(err.getMessage());
        }
    }
}
