Is there a way to check if java object changed after submit

Is there a way to check if the java object changed after submitting in JSF, without storing the instance manually or quering database before persist. I am using primefaces and omnifaces framework in my application.

@Named("bean")
public class bean implement serialization{ 
   private Person newPerson;

   public void doSave(ActionEvent event) {
        //compare person object
        if(newPerson.equal(submittedPerson)){
            //message to user for no changes to apply
             ----
        }else{
            //do persist
             ----
        };

//getter and setter
   ---

You could compute and compare the object's hash code before and after submission. That way, you will not have to store the actual object itself.
