OK, it is similar, but not exactly the same as your other exception, so I won't close this thread.
So the exception here says to me that you have a Getter method, but not a corresponding Setter method, and it appears that for that Object, Spring is requiring you to have both a Getter and Setter for it
You must have a getValidator() and a setValidator() method. Or maybe you can't have validator as an instance variable. I am not sure completely, but I would look at your code for a getter and setter, and if you have neither, then I would remove the validator instance variable.
Good Luck
