//Let's say you want to get all articles from a MongoDB database.
//First we create a repository interface which extends to the MongoDB repository => ArticleRepository.java:

package com.articlesPrac.articles.Repos;

import com.articlesPrac.articles.Article;
import org.bson.types.ObjectId;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;


@Repository
public interface ArticleRepository extends MongoRepository<Article, ObjectId> {
}

//Then we create a Service for the articles => ArticleService:

package com.articlesPrac.articles.Services;

import com.articlesPrac.articles.Article;
import com.articlesPrac.articles.Repos.ArticleRepository;
import org.bson.types.ObjectId;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.*;

@Service
public class ArticleService {
    @Autowired
    private ArticleRepository articleRepository;

    public List<Article> allArticles() {
        return articleRepository.findAll(); //Finds all the data in the DB
    }

}

//After this we create a controller for the articles => Article Controller.java:
package com.articlesPrac.articles.Controllers;

import com.articlesPrac.articles.Article;
import com.articlesPrac.articles.Services.ArticleService;
import org.bson.types.ObjectId;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.*;
import org.springframework.web.bind.annotation.*;

import java.util.*;


@RestController
@RequestMapping("/api/v1/articles")
public class ArticleController {
    @Autowired
    private ArticlService articleService;
	
  	//Get Request
    @GetMapping
    public ResponseEntity<List<Article>> getAllArticles() {
        return new ResponseEntity<List<Article>>(articleService.allArticles(), HttpStatus.OK);
    }


}
