Spring MVC- Hibernate: org.hibernate.exception.GenericJDBCException: Could not open connection

Question

I'm working on a maven sample project where in I use MySQL, Spring and Hibernate. I created a database using terminal in my mac. Used the following commands to log into mysql and create database and tables.

    $ sudo -s
    Password:
    bash-3.2# mysql -u root -p
    Enter password:

In my jdbc.properties file, I have this:

    jdbc.driverClassName = com.mysql.jdbc.Driver
    jdbc.url = jdbc:mysql://localhost:3306/sample
    jdbc.username = root    
    jdbc.password = root
    hibernate.dialect = org.hibernate.dialect.MySQLDialect
    hibernate.show_sql = true
    hibernate.format_sql = true

On launching the url, I get to see this,

HTTP Status 500 - Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection


exception:
    org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection

root cause:
    org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection

root cause:
    org.hibernate.exception.GenericJDBCException: Could not open connection

root cause:
    java.sql.SQLException: Access denied for user 'root '@'localhost' (using password: YES)

I'm not familiar using terminal and the commands. Can anyone let me know what is the issue here and what should be the jdbc.username and jdbc.password. I don't have a Query Browser, I've gotta use only the terminal.

I guess privileges are missing for "root@localhost"

Here are the steps to grant privileges

$ sudo -s
  Password:
  bash-3.2# mysql -u root -p
  Enter password:

After you are logged in, grant privileges to root@localhost

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'thepassword' WITH GRANT OPTION;
