Description

The generated Client Configurations class generates invalid properties annotation, when you use a title with uppercase characters. Camel case is not allowed for this annotation.

The yml

info:
  version: v1
  title: My Default API

Output is:

  @Bean
  @ConditionalOnProperty("myTestApi.security.client-id")
  @ConfigurationProperties("myDefaultApi.security.x")
  public ClientCredentialsResourceDetails resourceDetails() {
    ClientCredentialsResourceDetails details = new ClientCredentialsResourceDetails();
    details.setAccessTokenUri("test");
    return details;
  }

@ConfigurationProperties("myDefaultApi.security.x") is not allowed

see https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

The prefix value for the annotation must be in kebab case (lowercase and separated by -, such as acme.my-project.person).

openapi-generator version

4.0.3

Suggest a fix

Camel case title should be seperated by a dot with just lower case characters or should be completely lower case. my.default.api.security.x

or mydefaultapi.security.x
