[JAVA - Spring boot] Generated Spring boot project gives 404's with Java 11

Description

I created an API in Swaggerhub and wanted to generate a server stub. It let's me download a broken Spring boot project that doesn't work with Java 11 (boots perfectly but gives 404's on all requests).

Swagger-codegen version

I don't know, Swaggerhub generated it for me. I contacted their support and they told me to file a bug here.

Swagger declaration file content or url

See here: https://app.swaggerhub.com/apis/Leejjon/Example/1.0.0

Command line used for generation

Don't know, it happens on the backend of swaggerhub.

Steps to reproduce

• Go to https://app.swaggerhub.com/apis/Leejjon/Example/1.0.0
• Click export -> server stub -> spring
• Add Jaxb dependencies because it's no longer available in Java 11
• Run the project via mvn clean install spring-boot:run -Dserver.port=8080
• Go to localhost:8080/examples

Suggest a fix/enhancement

Start with the linked SwaggerHub API definition and reproduce the generated Spring Boot project using Java 11 and the stated Maven command. Check the generated server stub and its routing for the /examples request, then compare the result with the expected endpoint behavior. Done means the generated project starts successfully and no longer returns 404 for the documented request.
