Disable Feign logging on some API calls

I am using following configuration to enable logging for API calls made using feign

#Feign properties
feign:
  client:
    config:
      default:
        loggerLevel: full

My application is making calls to 3 APIs and feign is logging request and response JSON correctly for all the 3 APIs . I want to disable this logging for one of the API. Can you please let know on the necessary configuration. Thanx in advance

Solution

  • If you have 3 different feign clients for 3 APIs, then you can simply override logging level in this way (assuming that your feign client is called "feignClient2"):

    #Feign properties
feign:
  client:
    config:
      default:
        loggerLevel: full   
      feignClient2:
        loggerLevel: none

    But if you have one feign client for 3 endpoints, then the task becomes more complicated. You can inherit feign logger class (or any of its children classes, f.e. Slf4jLogger, if you use it now) and override its logRequest and logAndRebufferResponse methods to not log anything for specific endpoint (you can get the required information from request and response method parameters respectively). Then add FeignLoggerFactory bean with your own logger:

    @Bean
public FeignLoggerFactory feignLoggerFactory() {
    return new DefaultFeignLoggerFactory(new CustomLogger());
}

    It will override the default FeignLoggerFactory from FeignClientsConfiguration.

    In summary, I would recommend you to use the first option (with separate feign client). But if you choose the second one, I could help you to do it if you provide the example of your code.
