Difference between @GetMapping and @RequestMapping Spring?

Hello friends , if you are preparing for Java Developer and Spring Developer interviews then you must prepare for questions like difference between X and Y like @bean vs @component or @ReqestMapping or @GetMapping, those are very popular on Java interviews .

From last few episodes I have been sharing Java questions so one of my paid subscriber also ask if I can also share Spring related questions more, which I thought a good idea, so here we are.

In the past, I have also shared few questions on Spring boot like difference between RestController and Controller and in this article, we will take a look at another set of popular Spring annotations which is commonly related to processing HTTP request.

In Spring Framework, you will find variety of annotations that play a crucial role in shaping the behavior of their applications.

Two such annotations that are frequently used when dealing with web controllers are @RequestMapping and @GetMapping.

These annotations provide a way to define the mapping of incoming HTTP requests to methods within the controller, allowing for seamless handling of client requests.

However, while they might appear to be similar at first glance, they serve distinct purposes and offer specific functionalities for example @GetMapping is only for HTTP GET request while @RequestMapping can be used to process any HTTP methods like POST, PUT, GET and even DELETE. In this article, we'll delve into the depths of these annotations, uncovering their differences, use cases, and benefits.

Now, that you know the basic difference, its time for deep dive.
