### Чирцов Т А Группа 1.1
# Отчет по лабораторной работе "Task Management System"
## Описание работы
В ходе выполнения работы был создан RESTful веб-сервис для управления задачами с использованием Spring Boot. Приложение поддерживает базовые CRUD-операции: создание, редактирование, удаление и просмотр задач.
## Ход выполнения
1. **Создание проекта:**
- Проект был создан с помощью Spring Initializr с выбранными зависимостями: `Spring Web`, `Spring Data JPA`, `H2 Database`, `Spring Security`.
- Проект был импортирован в среду разработки IntelliJ IDEA.
2. **Создание модели задачи:**
- Создан класс `Task` с полями `id`, `title`, `description`, `status`, `createdAt`.
- Для аннотаций использовались `@Entity`, `@Id`, `@GeneratedValue(strategy = GenerationType.IDENTITY)`, `@Column`.
- Добавлены геттеры, сеттеры и методы `equals`, `hashCode`, `toString` для корректного сравнения объектов.
3. **Создание репозитория:**
- Создан интерфейс `TaskRepository`, который наследуется от `JpaRepository` для доступа к данным базы.
4. **Создание контроллера:**
- Создан класс `TaskController` с аннотацией `@RestController` и маршрутами CRUD операций.
- Методы контроллера:
- `@GetMapping("/api/tasks")` — получение списка всех задач.
- `@PostMapping("/api/tasks")` — добавление новой задачи.
- `@PutMapping("/api/tasks/{id}")` — обновление задачи по ID.
- `@DeleteMapping("/api/tasks/{id}")` — удаление задачи по ID.
- Добавлена обработка ошибок с возвратом корректных HTTP-кодов (`404 Not Found`, `201 Created`, `200 OK`, `204 No Content`).
5. **Настройка базы данных:**
- Настроен файл `application.yml` для использования базы данных H2 в режиме "in-memory".
- Включена консоль H2 для проверки данных по адресу [http://localhost:8080/h2-console](http://localhost:8080/h2-console).
6. **Добавление безопасности:**
- В `pom.xml` добавлена зависимость `spring-boot-starter-security`.
- Создан класс `SecurityConfig` для настройки базовой аутентификации.
- В `SecurityConfig`:
- Включена `HTTP Basic` аутентификация.
- Добавлен пользователь с логином `admin` и паролем `admin123`.
- Для упрощения тестирования CSRF защита была отключена.
## Результаты тестирования
Тестирование проводилось с использованием Postman. Были протестированы следующие эндпоинты:
1. **Создание задачи (POST /api/tasks)**:
```json
{
"title": "First Task",
"description": "Description of the first task",
"status": "Pending"
}
```
**Результат:** HTTP 201 Created, задача успешно добавлена.
2. **Получение всех задач (GET /api/tasks)**:
**Результат:** HTTP 200 OK, возвращается список задач.
3. **Обновление задачи (PUT /api/tasks/1)**:
```json
{
"title": "Updated Task",
"description": "Updated description",
"status": "Completed"
}
```
**Результат:** HTTP 200 OK, данные задачи обновлены.
4. **Удаление задачи (DELETE /api/tasks/1)**:
**Результат:** HTTP 204 No Content, задача успешно удалена.
5. **Получение несуществующей задачи:**
**Результат:** HTTP 404 Not Found.
## Выводы
В ходе работы было создано полноценное RESTful-приложение с поддержкой аутентификации и всех CRUD операций для управления задачами. Настроена база данных H2 и реализована базовая защита через Spring Security.
Для тестирования использовались запросы через Postman и проверка базы данных через консоль H2.
