What do you need to make a chat in spring?

Question

Spring

It is necessary to make the chat not a group one, but tables person to person could communicate. At what one person has several chats. I don’t know where to look, in terms of what is needed so that a message comes to the client side (React js) immediately. back to spring. In principle, I understood the structure of the database, I did not understand only how to show a new message to two clients at once.
