Access service in bean validation method

[acaciobernardo]

I am new to Spring, so this should be simple, but I searched everywere and still have no solution:

I want to invoke a service that validates a value inside the validation method of the model bean, but autowire doens't work there.. So I got this service class:

@Service("globalServices")
public class GlobalServices {
....
@Autowired
	private ValidaNIBSP validaNIBSP;
	
	public String validaNIB (...) {
		return validaNIBSP.execute(...);
		
	}
...

And my model:

public class SeguradoDTO implements Serializable {

  ...
        // executed in validation of edicao view state
	public void validateEdicao(ValidationContext context) {
		
		MessageContext messages = context.getMessageContext();
		messages.clearMessages();		
                 ...

        globalServices.validaNIBSP(...); // how to make this possible????

Autowire globalServices doesn't work, because the bean SeguradoDTO is just de model associated with the form. So is not part of the ApplicationContext?

Thanks for your help in advance.
