How to map multiple parameter names to POJO when b

问题:

My question is actually a spin-off of this question as seen here... so it might help to check that thread before proceeding.

In my Spring Boot project, I have two entities Sender and Recipient which represent a Customer and pretty much have the same fields, so I make them extend the base class Customer;

Customer base class;

@MappedSuperclass
public class Customer extends AuditableEntity {

    @Column(name = "firstname")
    private String firstname;

    @Transient
    private CustomerRole role;

    public Customer(CustomerRole role) {
        this.role = role;
    }

    //other fields & corresponding getters and setters
}

Sender domain object;

@Entity
@Table(name = "senders")
public class Sender extends Customer {

    public Sender(){
        super.setRole(CustomerRole.SENDER);
    }
}

Recipient domain object;

@Entity
@Table(name = "recipients")
public class Recipient extends Customer {

    public Recipient(){
        super.setRole(CustomerRole.RECIPIENT);
    }
}

NOTE - Sender and Recipient are exactly alike except for their roles. These can be easily stored in a single customers Table by making the Customer base class an entity itself, but I intentionally separate the entities this way because I have an obligation to persist each customer type in separate database tables.

Now I have one form in a view that collects details of both Sender & Recipient, so for example to collect the firstname, I had to name the form fields differently as follows;

Sender section of the form;

<input type="text" id="senderFirstname" name="senderFirstname" value="$!sender.firstname">

Recipient section of the form;

<input type="text" id="recipientFirstname" name="recipientFirstname" value="$!recipient.firstname">

But the fields available for a customer are so many that I'm looking for a way to map them to a pojo by means of an annotation as asked in this question here. However, the solutions provided there would mean that I have to create separate proxies for both domain objects and annotate the fields accordingly e.g

public class SenderProxy {

    @ParamName("senderFirstname")
    private String firstname;

    @ParamName("senderLastname")
    private String lastname;
    //...
}

public class RecipientProxy {

    @ParamName("recipientFirstname")
    private String firstname;

    @ParamName("recipientLastname")
    private String lastname;
    //...
}

So I got very curious and was wondering, is there a way to map this Proxies to more than one @ParamName such that the base class for example can just be annotated as follows?;

@MappedSuperclass
public class Customer extends AuditableEntity {

    @Column(name = "firstname")
    @ParamNames({"senderFirstname", "recipientFirstname"})
    private String firstname;

    @Column(name = "lastname")
    @ParamNames({"senderLastname", "recipientLastname"})
    private String lastname;

    @Transient
    private CustomerRole role;

    public Customer(CustomerRole role) {
        this.role = role;
    }

    //other fields & corresponding getters and setters
}

And then perhaps find a way to select value of fields based on annotation??
