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 3.0 feature, add the following element declaration into your server.xml file, inside the featureManager element:

<feature>mpOpenAPI-3.0</feature>

Examples

Configure OpenAPI documentation for a multi-module application

You can specify MicroProfile Config properties to configure the Microprofile OpenAPI feature to merge OpenAPI documentation for multiple applications or modules into a single document.

In the following microprofile-config.properties file example, an OpenAPI document is configured for the sample_app application, which consists of an EAR file with five web modules.

mp.openapi.extensions.liberty.merged.include=all
mp.openapi.extensions.liberty.merged.exclude=sample_app/module-3,sample_app/module-5
mp.openapi.extensions.liberty.merged.info=
{
  "title": "A multi-module sample application",
  "description": "This is a sample application.",
  "termsOfService": "http://example.com/sample_app/terms",
  "contact": {
    "name": "API Support",
    "url": "http://www.example.com/sample_app/support",
    "email": "[email protected]"
  },
  "license": {
    "name": "License 2.0",
    "url": "https://www.example.org/licenses/LICENSE-2.0.html"
  },
  "version": "2.0.1"
}

  • The mp.openapi.extensions.liberty.merged.include property specifies that all five modules are included in the final OpenAPI document.

  • The mp.openapi.extensions.liberty.merged.exclude overrides the mp.openapi.extensions.liberty.merged.include property to exclude the module-3 and module-5 web modules.

  • The mp.openapi.extensions.liberty.merged.info property sets the info section for the final OpenAPI document, which documents web modules 1, 2, and 4.
