[JAVA] beta3 adds springfox import in spring generator

Description

I have upgraded from beta2 to beta3 and the java spring code generated from the api yaml file contains the import:

springfox.documentation.annotations.ApiIgnore

but the compiler fails on this import.

openapi-generator version

beta3, was working in beta2

OpenAPI declaration file content or url

paths:
  /endpoint:
    post:
      summary: Whatever
      tags:
        - endpoint
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/Whatever'
      responses:
        "201":
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Something'
        "400":
          $ref: '#/components/responses/BadRequest'
        "404":
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Error'
        "500":
          $ref: '#/components/responses/InternalServerError'

Command line used for generation

Reproduce the beta3 issue with the spring generator and the provided Maven configuration using mvn clean generate-sources. Inspect the generated Java output for the springfox.documentation.annotations.ApiIgnore import and compare it with beta2 behavior. Done means the spring-generated code no longer contains an unresolved import and compiles successfully.
