    It should work fine. The error is just telling that ${topic.person} returns an instance of the br.com.gsc.model.tableMapping.User class which in turn doesn’t have a public String getUsername() method. One of those two facts is probably not what you expect. Fix the code accordingly. Perhaps it has to be a different type or the method is indeed missing/incorrect?
