+
+
+# Лабораторная работа по использованию RabbitMQ в Java Spring
+
+## Обзор проекта
+Проект включает:
+- **ProducerController**: отправка сообщений в очередь RabbitMQ.
+- **PublisherController**: публикация сообщений в обмен.
+- **Subscriber** и **Consumer**: приём сообщений.
+- **SubscriberWithRouting**: подписчик на очереди `info` и `error`.
+
+## Настройка окружения
+
+### 1. Запуск RabbitMQ
+Команда для запуска контейнера:
+```bash
+sudo docker run -d --hostname rabbitmq --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management
+```
+Веб-интерфейс будет доступен на `localhost:15672`, брокер сообщений — на `localhost:5672`.
+
+### 2. Установка зависимостей
+Убедитесь, что установлен JDK 23, и выполните:
+```bash
+mvn clean install
+```
+
+### 3. Запуск приложения
+Команда для запуска:
+```bash
+mvn spring-boot:run
+```
+Приложение откроется на `localhost:8080`.
+
+## Проверка работы с Curl
+
+### Тест 1: `ProducerController`
+**Метод:** POST  
+**URL:** `http://localhost:8080/api/producer/send?message=<ваше_сообщение>`
+
+**Пример:**
+```bash
+curl -X POST "http://localhost:8080/api/producer/send?message=Hello%20RabbitMQ"
+```
+**Результат:**
+```
+Сообщение добавлено в очередь: task_queue, текст: Hello RabbitMQ
+```
+
+### Тест 2: `PublisherController`
+**Метод:** POST  
+**URL:** `http://localhost:8080/api/publisher/publish?message=<сообщение>&routingKey=<ключ>`
+
+С ключом маршрутизации:
+```bash
+curl -X POST "http://localhost:8080/api/publisher/publish?message=Log%20message&routingKey=info"
+```
+Без ключа:
+```bash
+curl -X POST "http://localhost:8080/api/publisher/publish?message=Log%20message"
+```
+**Ответ:**
+```
+Сообщение отправлено в direct_logs с ключом: info
+```
+или:
+```
+Сообщение отправлено в logs без ключа
+```
+
+### Тест 3: `Subscriber`
+При публикации через `ProducerController` или `PublisherController`:
+```
+Получено сообщение: Log message
+```
+
+### Тест 4: `Consumer`
+При отправке сообщения в `task_queue`:
+```
+Получено сообщение из очереди задач: Hello RabbitMQ
+```
+
+### Тест 5: `SubscriberWithRouting`
+**Очередь `info`:**
+```bash
+curl -X POST "http://localhost:8080/api/publisher/publish?message=Informational%20message&routingKey=info"
+```
+**Результат:**
+```
+Информационное сообщение: Informational message
+```
+
+**Очередь `error`:**
+```bash
+curl -X POST "http://localhost:8080/api/publisher/publish?message=Error%20message&routingKey=error"
+```
+**Результат:**
+```
+Ошибка: Error message
+```
