[JAVA] library feign: How to add Feign Client Logging in SpringBoot through Application Properties?

[marcellodesales]

• I Can't get logging to work with SpringBoot's properties

Description

Desired Way:

• I created a client using the Swagger-Gen using lang=java and library=feign. I got the Invoker, model and api packages and I'm trying to get the logging in the Interface as follows:
• https://cloud.spring.io/spring-cloud-netflix/multi/multi_spring-cloud-feign.html#_feign_logging

logging:
  level:
    platform.client.parkingplus.api.ServicoPagamentoTicket2Api: DEBUG

feign:
  client:
    config:
      default:
        loggerLevel: FULL

Wokaround

• I could get it to work by creating a bean, but that's too evasive... I would not be able to change from SpringBoot's application.properties without a hack.

  @Bean
  public ServicoPagamentoTicket2Api ticketApi() {
    ApiClient client = new ApiClient();
    // https://stackoverflow.com/questions/42751269/feign-logging-not-working/59651045#59651045
    client.getFeignBuilder().logLevel(Level.HEADERS);
    client.setBasePath(properties.getHost());
    // Generated from swagger: https://demonstracao.parkingplus.com.br/servicos
    return client.buildClient(ServicoPagamentoTicket2Api.class);
  }
