Include the necessary dependencies, including the MongoDB driver. Step 2: Define a MongoDB Configuration: Create a configuration class with the necessary configurations for connecting to MongoDB, including the host, port, and database name. Step 3: Define a MongoDB Entity: Create a POJO (Plain Old Java Object) class to represent your data model. Annotate this class with the necessary MongoDB annotations to define the collection name and field mappings. Step 4: Create a Repository Interface: Define a repository interface that extends the appropriate MongoDB repository interface. This interface will handle the CRUD (Create, Read, Update, Delete) operations for your MongoDB entity. Step 5: Implement Service Layer: Create a service class to handle business logic and interact with the MongoDB repository. Define methods for data manipulation and retrieval. Step 6: Implement Data Initialization (Optional): If required, initialize data in the database during application startup using data initialization scripts or methods. Step 7: Implement Controller for REST API: Create a controller class to define REST endpoints for interacting with the MongoDB data. Implement methods for handling HTTP requests, utilizing the service layer. Step 8: Test Endpoints: Test the REST API endpoints using tools like Postman or any other HTTP client to ensure the proper functioning of the MongoDB integration. Step 9: Run and Test the Application: Run the Spring Boot application and verify the integration by performing CRUD operations through the defined REST API endpoints. Step 10: Handle Exception and Error Scenarios: Implement error handling mechanisms to gracefully manage exceptions and errors that might occur during MongoDB integration. Implement proper logging and error response handling. 00:00 Introduction 01:06 Configuration 04:12 Best Practices 05:31 Repository 07:22 MongoRepository 09:10 @Document 09:51 @Id 11:39 Saving entity in db 18:10 Getting entity from db 22:36 Deleting entity from db 23:07 Updating entity in db
