Swagger is a powerful tool for designing, building, and documenting APIs. In this tutorial, we’ll explore how to integrate Swagger with a Spring Boot application. Swagger simplifies API development by providing a standardized way to describe and document RESTful APIs.
Before we begin, make sure you have the following installed:
- Java JDK (8 or later)
- Your favorite IDE (Eclipse, IntelliJ, or Visual Studio Code)
Step 1: Create a Spring Boot Project
You can use Spring Initializr (https://start.spring.io/) to generate a new Spring Boot project. Include the “Spring Web” and “Spring Boot DevTools” dependencies.
Alternatively, you can use the following Maven dependencies:
Step 2: Add Swagger Dependencies
Add the Swagger dependencies to your
Step 3: Configure Swagger in your Application
Create a Swagger configuration class in your project. This class will use SpringFox to enable Swagger for your Spring Boot application:
"your.package.name" with the base package of your Spring Boot application.
Step 4: Create a Sample Controller
Create a sample controller with some REST endpoints:
Step 5: Run Your Application
Run your Spring Boot application. Open your browser and navigate to
http://localhost:8080/swagger-ui.html. You should see the Swagger UI interface, allowing you to explore and interact with your API.
Congratulations! You’ve successfully integrated Swagger with your Spring Boot application. Swagger provides a powerful toolset for API development, making it easier to design, document, and test your APIs. Explore additional Swagger features and customize your documentation further to suit your project’s needs.
