**User Service Hibernate** — консольное Java-приложение для управления пользователями с помощью Hibernate и PostgreSQL.
4+
Реализованы основные CRUD-операции (создание, чтение, обновление, удаление) через удобное меню.
5+
6+

7+
8+
## Технологии
9+
10+
- Java 22
11+
- Hibernate ORM
12+
- PostgreSQL (через Docker)
13+
- SLF4J + Logback (логирование)
14+
- JUnit 5 (тестирование)
15+
- Maven (сборка и зависимости)
16+
- Checkstyle (проверка стиля кода)
17+
18+

27+
```
28+
### 2 Запустить базу данных PostgreSQL
29+
```sh
30+
docker compose up -d
31+
```
32+
### 3. Собрать проект и проверить стиль кода
33+
34+
```sh
35+
mvn clean install
36+
mvn checkstyle:check
37+
```
38+
### 4. Запустить тесты
39+
