Spring & Spring Boot Annotations Series - #15 - @PostMapping and @RequestBody Annotations

Hi, welcome to Spring & Spring Boot Annotations Series. In this video, we will learn how to use @PostMapping and @RequestBody annotations in Spring boot applications.

@PostMapping is an annotation in Spring Boot framework used to map HTTP POST requests to specific controller methods. The @PostMapping annotation specifies the URL path for the mapped request and identifies the method to handle the request.

@RequestBody is another annotation in Spring Boot that is used to bind the HTTP request body to a Java object in the controller method. When a client sends an HTTP POST request with a request body, Spring Boot automatically maps the request body to a Java object that is annotated with the @RequestBody annotation. This allows the controller method to receive the data sent by the client in a structured format and use it for processing.

In combination, these annotations can be used to create a RESTful API with Spring Boot that receives structured data from the client in an HTTP POST request and then processes that data using a specific controller method.

Thank you so much for the detailed explanation. I've seen so many tutorial videos on how to use Spring annotations but yours are definitely the clearest ones. Congrats! Greetings from Mexico!

Great Learnings Pls post more videos on Spring Boot releated annotations

Hi Ramesh,
please make a video on REST api principle and explain some theoretical concepts, like why RESTfull is called an architectural style.
How these concepts are implemented in Java. So why there was a need of new api called JAX-RS and have jersey implementation. Is jax-rs built on top of servlet api. Also as spring provides its on implementation of rest not following jax-rs. But spring Boot follows uses jersey.
