Best implementation of the Swagger UI tool for your OpenAPI based Spring Boot REST server

Among the Swagger Tools is Swagger UI, an excellent tool for browsing an OpenAPI specification, the methods defined in the specification, the data models used in the specification. Swagger UI even lets you interact with the service from the documentation. It's a most useful take on "documentation", and to large measure is the whole reason for adopting OpenAPI/Swagger.

Unfortunately implementing the springfox-swagger-ui plugin in a Spring Boot Swagger application gives you a Swagger UI implementatation that's nowhere near as nice/capable as the demo app you see at petstore.swagger.io. There is zero documentation on how to implement the improved Swagger UI via the springfox-swagger-ui plugin. Instead, after quite a bit of experimentation, it seems one must turn to the Swagger UI Docker container.

Create a Spring Boot REST API using Swagger, OpenAPI, to "Generate Swagger OpenAPI REST API documentation for Spring Boot application"

The Swagger tools, and the OpenAPI format, are an excellent way to document REST API's and even to generate client or server stub libraries to ease implementation. The technology serves two purposes -- a) standardized documentation for REST API's, b) generating code from API documentation in several programming languages. An OpenAPI file is fairly simple to write, you declare REST endpoints, describe the parameters and the request type, and then describe responses. It allows you to define complex object models that can be used either as input to a service, or its output.

Unfortunately the Swagger website doesn't have adequate documentation of using the tools. And it proved difficult to find clear straight-forward tutorials showing how to get started. Even the most powerful tool can be hampered if folks are unable to use it.

The following tutorial is a complete demonstration of, starting from scratch, developing a small Spring Boot service using OpenAPI and the Swagger tools. We show how to go from an OpenAPI spec to generated Spring Boot code, and also how to generate an OpenAPI spec from running Spring Boot code. There are several issues with the workflow of generating code from the OpenAPI spec. It's more effective to instead write the service code, and add in the annotations required for the Swagger tools to generate the OpenAPI spec for you.

With the OpenAPI spec it's easy to produce interactive API documentation that programmers can try out directly in their web browser.
How to easily edit a Swagger/OpenAPI API specification using free tools The official way to edit a Swagger/OpenAPI document is using the Swagger Editor available through the swagger.io website, or to use the SwaggerHub website. The Editor can be run on your laptop inside a web browser which allows local JavaScript execution. As browsers tighten the screws on security the ability to do that may cease, and I see in the issue queue a request to make Electron versions of the Swagger tools. The SwaggerHub website is another option, especially as it offers lots of interesting features (at a fee). But, since OpenAPI is a free and open specification it's possible for others to develop tools. In this post we'll go over using the Swagger Editor, and using Atom to edit an OpenAPI specification.
Swagger and Open API Spec @codecampnyc 2016

Moving from "cloud-first" to "cloud-only" and therefore "API's" are more important than ever. Concept of the API Economy. Hence necessity for a better method to design REST-ful API's, and help others to use those API's. Another problem is the "Distributed Monolith" which is interlocking dependencies between microservices. Swagger is the solution.

Language agnostic. Helps to generate excellent documentation. No guesswork. Clearly documented REST API's.
Swagger tutorial -- How to add Swagger OpenAPI to your REST API documentation An introduction to Swagger/OpenAPI. A core idea given is documentation that's interactive, and unlike typical documentation as it appears in a slide deck. The power of having an API described in an industry-standard format is the wide variety of tools available.
SwaggerHub 101 An Introduction to Getting Started with SwaggerHub As the title suggest, this shows how to use SwaggerHub in a software development team. SwaggerHub covers a full life-cycle of API development in a team. Each project or "Organization" in SwaggerHub can have members and various settings. It can automatically generate a "mock API server" to try out the API directly via SwaggerHub.
