Hello👋, Its Rohan Kadam😊.
In the article, we will try to understand MongoDB and How to use the same using spring boot. Before jumping directly into code we should first understand certain sub-topics What is MongoDB? Why use MongoDB? and many more questions.
⚡What is MongoDB?
MongoDB is a document database with the scalability and flexibility that you want with the querying and indexing that you need. It stores data in flexible, JSON-like documents, meaning fields can vary from document to document and data structure can be changed over time.
The document model maps to the objects in your application code, making data easy to work with. Ad hoc queries, indexing, and real-time aggregation provide powerful ways to access and analyze your data. It is a distributed database at its core, so high availability, horizontal scaling, and geographic distribution are built-in and easy to use.
⚡Why use MongoDB?
MongoDB is built on a scale-out architecture that has become popular with developers of all kinds for developing scalable applications with evolving data schemas.
As a document database, MongoDB makes it easy for developers to store structured or unstructured data. It uses a JSON-like format to store documents.
This format directly maps to native objects in most modern programming languages, making it a natural choice for developers, as they don’t need to think about normalizing data. MongoDB can also handle high volume and can scale both vertically or horizontally to accommodate large data loads.
⚡How to implement MongoDB Using Spring Boot?
MongoDB is widely been used by industry today for developing fast and powerful apps. Its best known for its high-performance searching and querying. Today we are going to implement MongoDB using the spring boot and the programming language Java. This part of we going to cover the CRUD operations for the same.
Step 1: How to generate Spring Boot Project?
Step 2: Which dependencies should I include?
The Spring Data MongoDB project provides integration with the MongoDB document database. Key functional areas of Spring Data MongoDB are a POJO centric model for interacting with a MongoDB DBCollection and easily writing a Repository style data access layer.
Step 3: What will be the Configuration for Mongo DB?
Connection String:- It helps to set connections between ours application and database.
MongoTemplate:- The MongoTemplate class is the primary implementation of the MongoOperations interface which specifies the basic set of MongoDB operations. We can also use the MongoRepository interface to perform MongoDB operations. The implementation class of MongoRepository uses MongoTemplate bean at run time
Step 4: What will be the Document/Entity for MongoDB?
Step 5: What will be the Controller for MongoDB?
- Request Add and Update Request
2. User Response
3. User Controller
Step 6: What will be the Repository/DAO for MongoDB?
Step 8: What will be the business logic CRUD operations for MongoDB?
Step 7: What will be the final Output for MongoDb?
Step 8: Where do I find the full Codebase?

⚡Conclusion:-
In the article, we tried to answer some questions related to MongoDB and how to implement the same using Spring boot. MongoDB is a no-SQL fast and powerful database used by many fortune 500 companies to provide service to others.
