我有以下类结构...

export abstract class PersonBase {
    public toJSON(): string {

export class Person extends PersonBase {

    private readonly _firstName: string;

    public constructor(firstName: string, lastName: string) {
        this._firstName = firstName;
        this._lastName = lastName;
    }

    public get first_name(): string {
        return this._firstName;
    }

    public get last_name(): string {
        return this._lastName;
    }
}

export class DetailPerson extends Person {

    private _address: string;
