Spring lookup tables how to use them?

Question

Java

Good afternoon!

Before that, I did not use ORM, and therefore questions arise.

There is a reference table, say the type of document + additional characteristics of a particular type.

CREATE TABLE IF NOT EXISTS `doc_types` (
  `id` int NOT NULL,
  `name` varchar(255) NOT NULL,
  UNIQUE KEY (`id`)
) DEFAULT CHARSET=utf8;


CREATE TABLE IF NOT EXISTS `docs` (
  `id` int NOT NULL,
  `documentType`int NOT NULL,
  `content` varchar(200) NOT NULL,
  PRIMARY KEY (`id`,`documentType`)
) DEFAULT CHARSET=utf8;

INSERT INTO `doc_types` (`id`, `name`) VALUES
  (1, 'Внутренний оборот'),
  (2, 'Внешний оборот'),
  (3, 'Сервисный документ');

INSERT INTO `docs` (`id`, `documentType`, `content`) VALUES
  ('1', 1, 'Какой-то внутр документ'),
  ('2', 1, 'Какой-то внутр документ'),
  ('1', 2, 'Какой-то внеш документ'),
  ('1', 3, 'Какой-то сервисный документ');

There is a table-document, with a field of this type (1 piece).
those. The user selects a value from the reference book.

How does it work in spring?
the directory is also a pagingAndSorting repository and each entry is an entity?
