For further explanation, you can even use both at the same time.

<code>MongoRepository</code> is just an abstraction layer, like <code>MongoTemplate</code>, but with simpler interface. 

If you found doing some kind of operation is too complicated with Spring <a href="https://docs.spring.io/spring-data/mongodb/docs/current/reference/html/#repositories.query-methods.query-creation" rel="noreferrer">query-creation</a>, and somehow doesn't want to use <a href="https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.query-methods.at-query" rel="noreferrer"><code>@Query</code></a> (for example, you want IDE type hint when constructing queries), you can extend the <code>MongoRepository</code> and use <code>MongoTemplate</code> as the query mechanism.

First we extend our repository with our custom interface.

<pre><code>@Repository
public interface ArticleRepository extends MongoRepository&lt;Article, String&gt;, CustomArticleRepository {
}
</code></pre>

Then declare the interface.

<pre><code>public interface CustomArticleRepository {
 List&lt;Article&gt; getArticleFilteredByPage(int page, int num);
}
</code></pre>

And then implement our custom repository. We can autowire the <code>MongoTemplate</code> here and use it to query the database.

<pre><code>public class CustomArticleRepositoryImpl implements CustomArticleRepository {

 @Autowired
 MongoTemplate mongoTemplate;

 @Override
 public List&lt;Article&gt; getArticleFilteredByPage(int page, int num) {
 return mongoTemplate.findAll(Article.class)
 .skip(page * num)
 .take(num);
 }
}
</code></pre>

Last, we use the <code>ArticleRepository</code>.

<pre><code>@Service
public class ArticleServiceImpl {

 @Autowired
 private ArticleRepository articleRepository;

 public List&lt;Article&gt; getArticleByPage() {
 return articleRepository.getArticleFilteredByPage(1, 10);
 }
}
</code></pre>

I am new to Spring Boot and MongoDb. 
Trying some examples with Mongo Repositories and Spring Boot. 
But after going through some of the documents found that Mongo Template is will be a better option. Unable to get a proper Spring Boot with Mongo Template example.

<ol>
<li>Can someone please help me out with an example for the same.</li>
<li>Do we need to create a User defined Repositories interface and extend Repositories or CRUD Repository, while trying for Mongo Template ?</li>
</ol>

Spring Boot with MongoTemplate
