SpringBoot Swagger

Swagger is a popular tool for building, documenting, and testing RESTful APIs. Swagger UI provides a visual representation of the API, making it easier for developers to understand and consume the API.

To enable Swagger in a Spring Boot application, you need to add the following dependencies to your pom.xml file:

Next, create a configuration class for Swagger. For example, SwaggerConfig.java:

In the configuration class, you specify the type of documentation you want to generate (in this case, SWAGGER_2), and define which controllers and routes should be included in the documentation using the RequestHandlerSelectors and PathSelectors classes.

To test your Swagger configuration, start your Spring Boot application and navigate to http://localhost:8080/swagger-ui.html in your browser. You should see a UI that allows you to explore your API and test the different endpoints.

Here is an example of a simple car REST API using Swagger:
