spring-cloud-function-adapter-azure-web sample question

[eric950907]

I started the project with the README.adoc file of spring-cloud-function-adapter-azure-web, but I had a problem executing the curl -X GET http://localhost:7072/api/AzureWebAdapter/ command。I didn't change any code for the project, I started the project after downloading it, and this problem occurred
