    I'm not entirely certain that this question is a dupe, (only 90% sure), but this answer:

    Seems to have the information you need. Specifically, you should do this:

    I got it working by fetching an instance of the bean used in the constructor-arg out of the context and then populating it with the values that you are working with at run-time. This bean will then be used as the parameter when you get your factory-generated bean.

    public class X {
       public void callFactoryAndGetNewInstance() {
          User user = context.getBean("user");
          user.setSomethingUsefull(...);
          FileValidator validator = (FileValidator)context.getBean("fileValidator");
          ...
       }
    }
    

    I recommend reading the entire answer.
