This project is a Spring Boot application that integrates with MongoDB. It supports running both with and without Docker. Below are instructions for setting up the application in either environment.

• Java 11+
• Maven
• MongoDB (locally or via Docker)
• Docker (if using Docker setup)

• If you choose not to use Docker, you'll need to manually install MongoDB on your system and start the MongoDB service.
• Once MongoDB is running, update the MongoDB configuration in the Spring Boot application.

Edit the application.properties file located in the src/main/resources/ directory:

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=my_first_spring_project

Depending on your platform (Windows, macOS, Ubuntu), you can use the appropriate Maven wrapper command:

For Windows:

mvnw.cmd clean
mvnw.cmd install
mvnw.cmd spring-boot:run

For macOS/Linux/Ubuntu:

./mvnw clean
./mvnw install
./mvnw spring-boot:run

This will build and start the Spring Boot application.

You can use Docker to run both MongoDB and the Spring Boot application. This is the easiest setup as it automatically configures MongoDB and the application environment.

To start the services, run the following Docker commands from the root of your project:

docker-compose up --build

docker-compose up -d

This will build the project, set up MongoDB, and start the Spring Boot application.

Once the Spring Boot application is up and running, visit the following URL to access the Swagger UI, where you can test all available APIs:

Swagger UI - API Documentation

This application includes an additional feature that allows importing users from an external API into MongoDB.

• External API: http://localhost:8080/users/v1/
• Example Response:

  [
    {
      "id": "001",
      "username": "shubham",
      "email": "shubham@example.com"
    }
  ]

In the UserController, a new endpoint importUsers has been added to fetch all users from the external API and store them in the MongoDB database.

This project can be run both using a local MongoDB setup or using Docker for easier management. The application is also capable of fetching and storing data from an external API into MongoDB. For API testing, Swagger UI is available for easy interaction with the app's endpoints.
