Описание: 𝑫𝒆𝒔𝒆𝒓𝒊𝒂𝒍𝒊𝒛𝒂𝒕𝒊𝒐𝒏 𝒐𝒇 𝑱𝑺𝑶𝑵 𝑹𝒆𝒔𝒑𝒐𝒏𝒔𝒆 𝒕𝒐 𝑱𝒂𝒗𝒂 𝑪𝒐𝒍𝒍𝒆𝒄𝒕𝒊𝒐𝒏𝒔 𝑳𝒊𝒔𝒕 𝒐𝒓 𝑴𝒂𝒑 𝒖𝒔𝒊𝒏𝒈 𝑻𝒚𝒑𝒆 𝑹𝒆𝒇𝒆𝒓𝒆𝒏𝒄𝒆.

What is 𝑻𝒚𝒑𝒆 𝑹𝒆𝒇𝒆𝒓𝒆𝒏𝒄𝒆?

It is a class in 𝑶𝒃𝒋𝒆𝒄𝒕 𝑴𝒂𝒑𝒑𝒆𝒓 which can be used to directly 𝒎𝒂𝒑 𝒕𝒉𝒆 𝑱𝑺𝑶𝑵 𝒓𝒆𝒔𝒑𝒐𝒏𝒔𝒆 𝒊𝒏 𝒕𝒐 𝑱𝒂𝒗𝒂 𝑪𝒐𝒍𝒍𝒆𝒄𝒕𝒊𝒐𝒏𝒔 (List/Map)

𝑯𝒐𝒘 𝒊𝒕 𝒊𝒔 𝒖𝒔𝒆𝒇𝒖𝒍?
𝑱𝒂𝒗𝒂 𝒆𝒓𝒂𝒔𝒆𝒔 𝒕𝒚𝒑𝒆 𝒐𝒇 𝒅𝒂𝒕𝒂 𝒔𝒕𝒐𝒓𝒆𝒔 𝒅𝒖𝒓𝒊𝒏𝒈 𝒓𝒖𝒏 𝒕𝒊𝒎𝒆 so using Type Reference, Object mapper can understand which type of List or Map we want to convert in to.
