swagger-api / swagger-core

Examples and server integrations for generating the Swagger API Specification, which enables easy access to your REST API

Version Matrix

Swagger Core library

Build Status Maven Central

Javadocs for annotations with the current release are available online.

The goal of Swaggerâ„¢ is to define a standard, language-agnostic interface to REST APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. When properly defined via Swagger, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interfaces have done for lower-level programming, Swagger removes the guesswork in calling the service.

Swagger-core is the Java implementation of Swagger. Current version supports JAX-RS and plain servlets. Integration with the Play! framework has been moved to Swagger-Play.

Check out Swagger-Spec for additional information about the Swagger project, including additional libraries with support for SpringMVC, other languages and more.

The following methods are available to obtain support for Swagger:

  • The Swagger Google Group - This would normally be your first stop to get support for Swagger. Here you can find previously asked question, and ask new ones. When asking a question, please provide as much information as you can regarding the environment you use (development language, library, versions.
  • The Issues tab - Please open feature requests and bugs here. If you're not sure you encountered a bug, or if it's a general usage question, please use the Google Group mentioned above.
  • IRC! you can find us on freenode in the channel #Swagger. You can talk with us directly there.

Get started with Swagger!

See the guide on getting started with swagger to get started with adding swagger to your API. For 2.X see getting started with swagger 2.X.


The OpenAPI Specification has undergone 3 revisions since initial creation in 2010. The swagger-core project has the following compatibilities with the OpenAPI Specification:

Where is Scala support?

To allow independent development, scala support has been moved into a separate project. See the swagger-scala-module for details. Play! framework support has moved to swagger-play.


This is a project to build the swagger-core library, which is required for the Swagger implementation of the OpenAPI Spec.
