V1 Configuration

When installing the plugin with install(SwaggerUI), sensible default values will be used and can be overwritten when required.

By default, the swagger-ui is available at "localhost:8080/swagger-ui" (assuming the application is running on localhost:8080).

Swagger

Configuration of the Swagger-UI itself

install(SwaggerUI) {
    swagger {
        forwardRoot = false
        swaggerUrl = "swagger-ui"
        authentication = "MySwaggerAuth"
        onlineSpecValidator()
        displayOperationId = true
        showTagFilterInput = true
        sort = SwaggerUiSort.HTTP_METHOD
        syntaxHighlight = SwaggerUiSyntaxHighlight.MONOKAI
    }
    //...
}

• forwardRoot - whether to forward the "/"-route to the swagger-ui
• swaggerUrl - the url at which the swagger-ui is available
• authentication - the name of the authentication method to use for the Swagger-UI and OpenApi-Spec
• validatorUrl - Swagger UI can validate specs against an online validator. This option can be used to enable/disable the validation or supply an url to a custom validator. disableSpecValidator() to disable validation (=default), specValidator("myUrl") to point to a custom validator, onlineSpecValidator() to use the default swagger-ui validator (https://validator.swagger.io/validator)
• displayOperationId - Whether to show the operation-id of endpoints in the list
• showTagFilterInput - Whether the top bar will show an edit box that you can use to filter the tagged operations.
• sort - Apply a sort to the operation list of each API
• syntaxHighlight - Syntax coloring theme to use

install(SwaggerUI) {
    defaultUnauthorizedResponse = {
        description = "Username or password invalid."
        // ...

    defaultSecuritySchemeName = "MyBasicAuth"
    defaultSecuritySchemeNames = setOf("MyBasicAuth", "MyTokenAuth")
    automaticTagGenerator = { url -> url.firstOrNull() }
    schemasInComponentSection = true
    examplesInComponentSection = true

• defaultUnauthorizedResponse - the response-information for a "401 Unauthorized"-response to automatically add to each protected route - if not specified otherwise. See Responses for more information.
