When doing hibernate, throw the following exception:

The fault is probably the previous password to change the MySQL (there is a problem with the law).

Error code 1045
Access denied for user ' root ' @ ' localhost ' (using Password:yes)

The workaround is to reset the root password, and under the Windows platform, follow the steps below:
1, log on to the system as a system administrator;
2, if the MySQL server is running, stop it.
      If it is a server running as a Windows service, go to Service Manager: Start menu-> Control Panel-> management tools-> Services
      If the server is not running as a service, you may need to use Task Manager to force it to stop.
3, create 1 text files, and place the following command on a single line:
      SET PASSWORD for ' root ' @ ' localhost ' = PASSWORD (' Mynewpassword '); br>      Save the file with any name. In this case, the file is C:/mysql-init.txt.
4, enter DOS command prompt: Start menu-> run-> cmd
      Assume you have MySQL installed to c:/mysql. If you have MySQL installed in another location, please adjust the following command accordingly.
      at DOS command prompt, execute command:
            c:/> c:/mysql/bin/mysqld-nt nit-file=c:/mysql-init.txt  

When the server starts, executes the contents of the file named by the "--init-file" option, which reads the SQL command from the specified file at startup, and changes the root user password. After the server has successfully started, you should delete the C:/mysql-init.txt.
5, stop the MySQL server, and then restart it in normal mode. If you run the server as a service, you should start it from the Windows Services window. If you start the server manually, you can use the command as you normally would.
You should be able to connect using the new password.
