I have 3 Tables in MySQL. Users, Roles, Accounts.

Users table has foreign key to Roles : User.roleId -> Roles.roleId One To Many. Primary key userId.

Accounts table has foreign key to Users : Accounts.accountId -> Users.userId One To One. Primary key accountId

Ccreating new User object

@Override
    public void registerUser(Registration reg) {
        User newUser = new User();
        newUser.setUsername(reg.getEmail());
        newUser.setPassword(reg.getPassword());

        genericDao.put(newUser);
        Integer userId = genericDao.getByName(User.class, "username", reg.getEmail()).get(0).getUserId();
        genericDao.put(new Account(userId));
    }

I have Exception on genericDao.put(newUser); method invoke. Inside this method is only sessionFactory.getCurrentSession().save(obj); Role object I don't create. So User.account and User.role are NULL. Also in MySQL default value configured.

The exception is quite clear: the role column (in table Roles) may not be null. Given the stack trace, I assume you're saving a user which has an association with a role, and this role has a null role field. Since you configured the association to be cascaded, the role is also saved, and since it has a null role, the insert fails.

EDIT: the new error shows that the column Users.roleId can't be null in database. So you must set a role on your user before savinf it. Specifying a default value for this column in the database is useless, because the default value will only be used if no value is specified for this column in the insert statement. But Hibernate will always specify a value. Default values are a bad idea anyway, because Hibernate isn't aware of them and thus can't have them in the entities without refreshing them.

Side note: if you don't generate the database schema from the annotations on the entities, then you shouldn't specify the nullable, unique, length attributes of these annotations. Especially if they're in contradiction with the actual column definition in the database. It makes things extremely confusing to have a column annotated with nullable=true when the column is in fact not nullable.

Thanks for your answer. This was really fail. Unfortunately even only CascadeType.DELETE throw this Exception. But for roleId row.

Is Roles.roleId an auto-increment column?

Edit your question, paste the code you're using to create the user and role, and paste the full stack trace you get.
