      for use, reproduction, or distribution of Your modifications, or

      for any such Derivative Works as a whole, provided Your use,

      reproduction, and distribution of the Work otherwise complies with

      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,

      any Contribution intentionally submitted for inclusion in the Work

      by You to the Licensor shall be under the terms and conditions of

      this License, without any additional terms or conditions.

      Notwithstanding the above, nothing herein shall supersede or modify

      the terms of any separate license agreement you may have executed

      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade

      names, trademarks, service marks, or product names of the Licensor,

      implied, including, without limitation, any warranties or conditions

      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

      PARTICULAR PURPOSE. You are solely responsible for determining the

      liable to You for damages, including any direct, indirect, special,

      incidental, or consequential damages of any character arising as a

   9. Accepting Warranty or Additional Liability. While redistributing

      the Work or Derivative Works thereof, You may choose to offer,

      and charge a fee for, acceptance of support, warranty, indemnity,

      or other liability obligations and/or rights consistent with this

      License. However, in accepting such obligations, You may act only

      on Your own behalf and on Your sole responsibility, not on behalf

      of any other Contributor, and only if You agree to indemnify,

      defend, and hold each Contributor harmless for any liability

      incurred by, or claims asserted against, such Contributor by reason

      of your accepting any such warranty or additional liability.

# NaC2TMFService

A Spring Boot application that manages NOKIA's Network as Code (NaC) resource specifications and integrates with TM Forum (TMF) APIs for resource inventory management. The service synchronizes network resources (IMSI, Radio, QoS, KPI) with a TMF-compliant resource catalog via REST APIs and asynchronous messaging through ActiveMQ.

## Features

- **Resource Specification Management**: Upload and manage resource specifications in a TMF API-compliant format

- **Resource Creation**: Automatically create and update IMSI, Radio, and QoS resources in the TMF inventory

- **Scheduled Updates**: Periodically synchronize resources on a configurable schedule (default: 3 minutes)

- **Message-Driven Architecture**: Process resource events through ActiveMQ with Apache Camel routing

- **Authentication**: Secure API communication via Keycloak OAuth2/OIDC integration

- **Containerized Deployment**: Docker support for easy deployment

## Prerequisites

- Java 17+

- Maven 3.9+

- ActiveMQ 5.18+

- Keycloak 21+

- Docker & Docker Compose (optional, for containerized deployment)

## Quick Start

### Local Development

1. **Clone the repository**

   ```bash

   git clone <repository-url>

   cd NaC2TMFService

   ```

2. **Install local dependencies**

   ```bash

   mvn install:install-file \

     -Dfile=libs/org.etsi.osl.model.tmf-1.1.0.jar \

     -DgroupId=org.etsi.osl \

     -DartifactId=org.etsi.osl.model.tmf \

     -Dversion=1.1.0 \

     -Dpackaging=jar

   ```

3. **Configure the application**

   - Edit `src/main/resources/application.yml` to set:

     - ActiveMQ broker URL

     - Keycloak authentication endpoints

     - TMF API base URL and credentials

4. **Build the application**

   ```bash

   mvn clean package

   ```

5. **Run the application**

   ```bash

   mvn spring-boot:run

   ```

The application will start on a random port (configured as port 0). Check the logs for the actual port.

### Docker Deployment

Build and run the Docker image:

```bash

docker build -t nac-service:latest .

docker run -e SPRING_APPLICATION_JSON='{"spring.activemq.brokerUrl":"tcp://activemq:61616"}' nac-service:latest

```

Or use Docker Compose:

```bash

docker-compose up

```

## Configuration

Configure the application via `src/main/resources/application.yml`:

### Core Settings

```yaml

spring:

  activemq:

    brokerUrl: tcp://localhost:61616

    user: artemis

    password: artemis

server:

  port: 0  # Random port

resource:

  specs:

    directory: src/main/resources/resourceSpecifications

  update:

    interval: 180000  # 3 minutes

nac:

  api:

    baseUrl: http://172.21.32.85:8008

    tenant: valencia_upv

    timeout:

      connect: 5000

      read: 30000

```

### Environment-Specific Profiles

- `application-docker.yml`: Docker-specific configuration

- Override settings via environment variables or `SPRING_APPLICATION_JSON`

## Architecture

### Component Overview

- **Application**: Spring Boot entry point with scheduled resource updates (`ResourceServiceApplication.java`)

- **Service Layer**: Business logic for resource management (`ResourceService`, `ResourceSpecificationUploader`, `ResourceSender`)

- **API Clients**: TMF Resource Specification and Inventory API integration

- **Message Routes**: Apache Camel routes for ActiveMQ event processing

- **Mappers**: Object transformation between NaC domain models and TMF API models

### Data Flow

1. Application startup loads resource specifications from JSON files

2. Specifications are uploaded to TMF Resource Specification API

3. Scheduled task periodically creates/updates resources via TMF Inventory API

4. ActiveMQ messages trigger resource updates through Camel routes

5. All API calls are authenticated via Keycloak

## Building

### Compile and test

```bash

mvn clean package

```

### Skip tests

```bash

mvn clean package -DskipTests

```

### Run specific test

```bash

mvn test -Dtest=AppTest

```

## Running

### Local execution

```bash

mvn spring-boot:run

```

### Using JAR

```bash

java -jar target/org.etsi.osl.nac-1.0-SNAPSHOT.jar

```

### With custom configuration

```bash

java -Dspring.config.location=file:./application-custom.yml -jar target/org.etsi.osl.nac-1.0-SNAPSHOT.jar

```

```

## Troubleshooting

### ActiveMQ Connection Error

Ensure ActiveMQ is running and accessible at the configured broker URL. Default: `tcp://localhost:61616`

### Keycloak Authentication Failure

Verify Keycloak credentials and URL in configuration. Token acquisition is cached for performance.

### Resource Specification Upload Fails

Check that resource specification JSON files exist in `src/main/resources/resourceSpecifications/` and follow the TMF format.

### Port Already in Use

The application uses port 0 for dynamic allocation. If needed, configure a specific port in `application.yml` under `server.port`.

## Contributing

1. Follow the existing code structure and naming conventions
