I have the following classes - 

**Employee**

```

public class Employee {

    private String firstName ;
    private String lastName ;
    private String emailAddress ; 
    private String ssn ;
}

```

**Payroll**

```

public class Payroll {

    // different payroll related fields

    private Employee emp ;

}

```

**HR**

```

public class HR {

    // different HR related fields

    private Employee emp ;

}

```

Now when I serialize my Payroll class, I don't want to serialize my ssn field from Employee class.

Where as when I serialize my HR class, I don't want to serialize my emailAddress field from Employee class.

How I can dynamically exclude fields from serializing by using Jackson JSON API?
