+# Лабораторная работа 3. REST API, Gateway и синхронный обмен между микросервисами
+### Задание на лабораторную работу
+1. Создать 2 микросервиса, реализующих CRUD на связанных сущностях.
+2. Реализовать механизм синхронного обмена сообщениями между микросервисами.
+3. Реализовать шлюз на основе прозрачного прокси-сервера nginx.
+
+***
+### Как запустить лабораторную работу
+Для сборки и запуска программ необходимо перейти в директорию с файлом `docker-compose.yaml` и выполнить команду:
+``` 
+docker-compose up -d
+```
+***
+### Описание работы
+Были созданы два микросервиса на *java*, каждый реализует CRUD-операции: список записей, подробности конкретной записи, создание, удаление и изменение записи.
+Микросервисы реализованы при помощи фреймворка *spring*.
+
+**Описание сущностей:**
+- *user* - пользователь. Поля: *id* (уникальный идентификатор пользователя), *fullName* (ФИО), *phoneNumber* (номер телефона), *role* (роль - ученик/репетитор).
+- *message* - сообщение. Поля: *id* (уникальный идентификатор сообщения), *text* (текст), *status* (статус - отправлено/получено/прочитано), *date* (дата отправки), *userId* (id пользователя).
+
+Сущности связаны отношением один-ко-многим (пользователь-сообщения).
+
+**Реализация синхронного обмена:**
+
+Синхронный обмен между сообщениями реализуется при помощи RestTemplate. 
+При получении информации о сообщении через GET запрос к user-service получаются данные о пользователе-отправителе сообщения.
+
+Пример реализации при получении записи о сообщении в `MessageService`:
+```
+private final MessageRepository messageRepository;
+private final RestTemplate restTemplate;
+private final String URL = "http://user-service:8085/user/";
+
+@Autowired
+public MessageService(MessageRepository messageRepository, RestTemplate restTemplate) {
+    this.messageRepository = messageRepository;
+    this.restTemplate = restTemplate;
+}
+
+@Transactional(readOnly = true)
+public MessageWithUserInfoDto findMessage(Long id) {
+    final Message message = messageRepository.findById(id).orElse(null);
+    if (message == null) {
+        throw new MessageNotFoundException(id);
+    }
+    UserInfoDto userInfo = restTemplate.getForObject(URL + message.getUserId(), UserInfoDto.class);
+    return new MessageWithUserInfoDto(message, userInfo);
+}
+```
+
+**Dockerfile**
+
+Используется базовый образ *openjdk:17-jdk*, на основе которого будет создан контейнер. 
+Внутри контейнера создается директория `/usr/src/app/`, после устанавливается рабочая директория и файлы из каталога, где находится Dockerfile, копируются внутрь контейнера в директорию `/usr/src/app/`.
+Выполняется сборка проекта с помощью инструмента gradlew. Задается порт и указывается точка входа для контейнера. Запуск java-приложения осуществляется посредством запуска jar-файла.
+
+Содержимое `Dockerfile` для сервиса `user-service`:
+```
+FROM openjdk:17
+RUN mkdir -p /usr/src/app/
+WORKDIR /usr/src/app/
+COPY . /usr/src/app/
+RUN ./gradlew clean build
+EXPOSE 8085
+ENTRYPOINT ["java","-jar","build/libs/user-service-1.0-SNAPSHOT.jar"]
+```
+Аналогично был составлен `Dockerfile` для сервиса `message-service`.
+
+**Файл конфигурации nginx.conf**
+
+Файл `nginx.conf` содержит конфигурацию для сервера *nginx*. 
+Конфигурация позволяет перенаправлять запросы, начинающиеся с /user-service/ на сервер user-service на порту 8085, а запросы, начинающиеся с /message-service/, на сервер message-service на порту 8086.
+```
+server {
+listen      80;
+listen      [::]:80;
+server_name localhost;
+
+    location /user-service/ {
+        proxy_pass       http://user-service:8085/;
+        proxy_set_header Host      $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header X-Forwarded-Prefix /user-service;
+    }
+
+    location /message-service/ {
+        proxy_pass       http://message-service:8086/;
+        proxy_set_header Host      $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header X-Forwarded-Prefix /message-service;
+    }
+}
+```
+
+**Файл конфигурации docker-compose.yml**
+
+В файле `docker-compose.yml` указана версия синтаксиса *Docker Compose*, определен список сервисов, которые будут развернуты в приложении, и определена сеть с именем "network", которая будет использоваться для связи между контейнерами.
+Файл определяет три сервиса: *user-service*, *message-service* и *nginx*. Для сервисов user-service и message-service используются образы приложений, созданные при помощи Dockerfile.
+Сервис *nginx* использует образ *nginx*.
+Параметр *depends_on* определяет зависимости сервисов (*nginx* зависит от сервисов *user-service* и *message-service* и разворачивается только после их запуска), в *ports* настраивается проброс портов.
+```
