N.B : my db password is something like that : test@@123$$*

any help guys ?

You should remove @ from password or replace it with %40 in your URL to not confuse with the '@' in your database URL. example :

before :

jdbc:mysql://username:pass@word@localhost:3306/dbname

after :

jdbc:mysql://username:pass%40word@localhost:3306/dbname
