In this comprehensive tutorial on Spring Boot Swagger UI, we dive into the powerful combination of Spring Boot and Swagger to simplify API documentation and testing.
Spring Boot is a popular framework for building Java applications, while Swagger is an open-source set of rules, specifications, and tools for developing and describing RESTful APIs. With Swagger UI, developers can create interactive and human-readable API documentation effortlessly.
In this video, we cover the following key topics:
Introduction to Spring Boot and Swagger UI
Setting up a Spring Boot project
Integrating Swagger UI into a Spring Boot application
Configuring Swagger annotations to document APIs
Generating interactive API documentation with Swagger UI
Customizing the Swagger UI interface
Leveraging Swagger for API testing and exploration
Best practices for using Spring Boot Swagger UI
By the end of this tutorial, you'll have a solid understanding of how to integrate Swagger UI with your Spring Boot projects, enabling you to easily document, explore, and test your APIs. Whether you're a beginner or an experienced developer, this video will provide you with the necessary knowledge to leverage the power of Spring Boot Swagger UI.

3. What is Swagger?
Swagger is an open source set of rules, specifications, and tools for developing RESTful APIs.
● It provides a framework for developers to create interactive API documentation.
● The documentation generated by Swagger is both machine-readable and human-readable.
● Swagger helps in describing and documenting the different endpoints, parameters, responses, and other
details of an API.
● Developers can use Swagger to build APIs that are easier to understand and use by other developers.
● It simplifies the process of documenting and sharing API information, making it accessible to both humans
and machines.
● The Swagger framework enables developers to design and develop APIs that conform to industry standards
and best practices.
● By using Swagger, developers can ensure consistent and accurate documentation of their APIs, making it
easier for others to integrate with and consume their services.
4. Integration
We are going to add the following dependency
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
<version>2.0.0-M4</version>
</dependency>
Add the following configuration to rh SpringBootApplication
@SpringBootApplication(scanBasePackages = {"com.code.with.bisky.*","org.springdoc"})
Accessing swagger-UI
http://localhost:8991/swagger-ui.html
5. Document Rest Controller API’s
We can document our API’s with the following annotations
● @Operation
● @ApiResponses
● @ApiResponse
@Operation(summary = "Creates a new user")
@ApiResponses(value = {
@ApiResponse(responseCode = "201", description = "Created user"),
@ApiResponse(responseCode = "400", description = "Bad request"),
@ApiResponse(responseCode = "500", description = "Server Error")
})
