Basic fundamentals for swagger, open api and restdocs with spring boot

Documentation is an essential part of building REST APIs. In this tutorial, we’ll take a look at SpringDoc — a tool that simplifies the generation and maintenance of API docs based on the OpenAPI 3 specification for Spring Boot 1.x and 2.x applications.

Requirements

Documentation is an essential part of building REST APIs. In this tutorial, we’ll take a look at SpringDoc — a tool that simplifies the generation and maintenance of API docs based on the OpenAPI 3 specification for Spring Boot 1.x and 2.x applications.

Besides generating the OpenAPI 3 specification itself, we can integrate springdoc-openapi with Swagger UI so that we can interact with our API specification and exercise the endpoints.

The springdoc-openapi dependency already includes Swagger UI, so we’re all set here.

springdoc-openapi java library helps to automate the generation of API documentation using spring boot projects. springdoc-openapi works by examining an application at runtime to infer API semantics based on spring configurations, class structure and various annotations.

Automatically generates documentation in JSON/YAML and HTML format APIs. This documentation can be completed by comments using swagger-api annotations.

This library supports:

  • OpenAPI 3
  • Spring-boot (v1, v2 and v3)
  • JSR-303, specifically for @NotNull, @Min, @Max, and @Size.
  • Swagger-ui
  • OAuth 2
  • GraalVM native images
    • Documentation will be available in HTML format, using the official swagger-ui jars
    • The Swagger UI page will then be available at http://server:port/context-path/swagger-ui.html and the OpenAPI description will be available at the following url for json format: http://server:port/context-path/v3/api-docs
      • server: The server name or IP
      • port: The server port
      • context-path: The context path of the application
    • Documentation can be available in yaml format as well, on the following path : /v3/api-docs.yaml
