Creating Java REST API with Spring Boot , Spring Data JPA and MySQL | REST API CRUD Operations

Connecting Spring Boot Application with Database can be daunting for Java developers.
Hence, let us learn how to build and connect Java REST API with Spring Boot , Spring Data JPA and MySQL, extremely helpful for backend java developers. In this session, CRUD will be implemented and data will be stored in MySQL database. Data will also be updated, fetched and deleted from mysql.
Some key Spring Boot and Spring JPA annotations -
@SpringBootApplication , @RestController , @RequestBody , @RequestMapping , @GetMapping , @PostMapping , @PutMapping , @DeleteMapping , @Entity , @Table, @Id , @Service, @Override
Spring Boot REST API project with data persistence in the MySQL for Cloud Vendor Information Service with all 4 CRUD operations are developed in this session.
Spring data JPA and Spring Boot methods save() , findById(), findAll(), deleteById() are used.
CRUD operations will be implemented in this session with saving, fetching/ querying and deleting data from MySQL database.
Spring Boot is widely used for developing Microservices.

Excellent video. Whole CRUD operation explained in such a clear and informative way. Very useful for someone to get complete flow of Java Rest API framework.

[tejaguramkondam]

I watched plenty of videos to learn this but I didn't find another famous channel this is helpful maybe because they thought I knew Spring Boot so they just explained the code but your video is completely beginner friendly thanks, mam.

[tpccibh]

[hendrickx]

Note that if you're using Spring Boot 3 and above with this tutorial, the 'javax' namespace should be replaced by 'jakarta'.

[sachindrapandey]

This is great tutoroal to get the basic understanding of Springboot REST

[knowwhatyoudonot]

Kudos to you for creating a such a informative tutorial.

I found that the delete API is also giving 200 OK response even for the vendorId not present in the database. Also even I request delete for same vendorId again, it also gives success message.

[shivuss]

Very good lecture. For me, when using Spring Boot version 3 some imports (such as javax.persistence.Entity) need to be changed to jakarta.persistence.Entity
