How to fix a disappeared "Authorize" button

[kevinwallimann]

Before using the springdoc-openapi-scala library in our Spring Boot Application, we used the @SecurityScheme annotation on the SpringBootServletInitializer to make OpenAPI display the Authorize button on the swagger UI

import io.swagger.v3.oas.annotations.security.SecurityScheme
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer

@SecurityScheme(name = "bearer", in = SecuritySchemeIn.HEADER, `type` = SecuritySchemeType.HTTP, scheme = "bearer")
class ServletInitializer extends SpringBootServletInitializer {
// etc.

After adding this library, unfortunately the Authorize button disappeared. However, adding the following OpenApiCustomizer fixed the issue and brought the button back

  import io.swagger.v3.oas.models.security.SecurityScheme
  import org.springdoc.core.customizers.OpenApiCustomizer
  import za.co.absa.springdocopenapiscala.Bundle

  private val extraOpenAPICustomizer: OpenApiCustomizer = (openApi: OpenAPI) => {
    val securityScheme = new SecurityScheme()
      .name("bearer")
      .`type`(SecurityScheme.Type.HTTP)
      .scheme("bearer")
      .in(SecurityScheme.In.HEADER)
    openApi.getComponents.addSecuritySchemes("bearer", securityScheme)
  }

  private val bundle = new Bundle(Seq(extraOpenAPICustomizer))

Note: springdoc-openapi-scala-2_2.12 v0.2.0 was used.
