MicroProfile OpenAPI

This feature provides support for the Eclipse MicroProfile OpenAPI specification for enterprise Java.

You can use MicroProfile Config properties to provide configuration values for MicroProfile OpenAPI. For more information, see MicroProfile Config Properties: OpenAPI.

Enabling this feature

To enable the MicroProfile OpenAPI 1.0 feature, add the following element declaration into your server.xml file, inside the featureManager element:



Configure MicroProfile OpenAPI documentation endpoints

MicroProfile OpenAPI generates and serves OpenAPI documentation for Jakarta RESTful Services or JAX-RS applications that are deployed to the Open Liberty runtime. The OpenAPI documentation is served from the <host>:<port>/openapi endpoint and a user interface for browsing this documentation is served from the <host>:<port>/openapi/ui endpoint.

You can configure the paths for these endpoints. Specify the docPath and uiPath attributes for the mpOpenAPI element in your server.xml file. For example, the following configuration sets the OpenAPI documentation for an appA application to /appA/openapi, while the UI to browse that documentation is available at /appA/openapi/docUi:

<mpOpenAPI docPath="/appA/openapi" uiPath="/appA/openapi/docUi" />

When the uiPath attribute is not set, it defaults to the value of the docPath attribute with /ui appended.
