How to Build REST APIs with Spring Boot

In this tutorial, we will learn how to build REST APIs using Spring Boot, one of the most powerful frameworks for developing Java applications. We’ll go through the following steps:

Setting Up the Spring Boot Project

To start, we need to set up a Spring Boot project. This can be done easily using Spring Initializr or through your IDE like IntelliJ IDEA or Eclipse. Here’s how you can do it...

Creating the Model Class

Now, let's create a model class that will represent the data for our API. The model will be a simple object like a 'User' with fields such as 'name' and 'email'...

Creating the Controller Class

Next, we need to create a REST controller that will handle the HTTP requests. This controller will use Spring's @RestController annotation to define endpoints...

Testing the API

Once the API is created, it's time to test it. You can use tools like Postman or cURL to send HTTP requests to the REST API and ensure everything is working properly...

Conclusion

By following the above steps, you can easily create a REST API using Spring Boot. Whether you are building microservices, web applications, or APIs, Spring Boot simplifies the process, making it quick and efficient...
