Feign logging not working when alter level

stackoverflow.com › questions › 42751269 › feign-logging-not-working-when-alter-level

You need to configure logging in application.properties as below:

logging.level.<package path>.MyClient=DEBUG

If you're using application.yml then:

logging.level.<package path>.MyClient: DEBUG

The log level can be set to tell Feign how much to log.

Options are:

NONE, No logging (DEFAULT)
BASIC, Log only the request method and URL and the response status code and execution time
HEADERS, Log the basic information along with request and response headers
FULL, Log the headers, body, and metadata for both requests and responses

Example:

logLevel(feign.Logger.Level.NONE)
or
logLevel(feign.Logger.Level.BASIC)
or
logLevel(feign.Logger.Level.HEADERS)
or
logLevel(feign.Logger.Level.FULL)

This is how i was able to log using Custom Config class

Note Feign logging only responds to the DEBUG level.

Config Class

@Configuration
public class UserClientConfig {

    @Bean
    Logger.Level feignLoggerLevel() {
        return Logger.Level.HEADERS;
    }
}

Client

@FeignClient(name = "User", url = "http://localhost:8080",configuration=UserClientConfig.class)
public interface UserClient {

    @RequestMapping(method = RequestMethod.GET, value = "/user")
    List<User> getAllUsers();    

}

application.properties

logging.level.<pcakgepath>.UserClient: DEBUG
