Retrofit - Log4j

I use Retrofit in a java application to access api-rest.

I'm using simple code:

RestAdapter.Builder().setEndpoint(uri).setLogLevel(RestAdapter.LogLevel.HEADES_AND_ARGS).setConverter(new GsonConverter(gson)).setClient(httpClient).build();

is possible mapping retrofit log to log4j ?

you can also use the log from okhttp , the snapshot from the version 2.6.0 which is introduced in the beta2 version of retrofit and going live soon is currently working fine, you can see how to implement it on this guide https://futurestud.io/blog/retrofit-2-log-requests-and-responses/ pretty easy to use and easy to implement.

You can do something like below:

new RestAdapter.Builder()
    .setLogLevel(LOGGER.isDebugEnabled() ? retrofit.LogLevel.FULL : retrofit.LogLevel.BASIC)
    .setLog(LOGGER.isDebugEnabled() ? LOGGER::debug : LOGGER::info)

retrofit.LogLevel is used to specify how much detailed logging you require from Retrofit.

An implementation of retrofit.RestAdapter.Log is passed to the setLog() of RestAdapter. RestAdapter delegates all its internal logging to log4j Logger in this case.

Here LOGGER is something that you would initialize like below

private static final org.apache.log4j.Logger LOGGER = org.apache.log4j.Logger.getLogger(SomeClass.class);

LOGGER::debug in Java 8 is equivalent to the below anonymous class

 new retrofit.RestAdapter.Log() {
      @Override
      public void log(String message) {
          LOGGER.debug(message);
      }
 }

The RestAdapter.Builder has method setLog(Log) which get's RestAdapter.Log interface as parameter. This interface looks like below:

 /** Simple logging abstraction for debug messages. */
  public interface Log {
    /** Log a debug message to the appropriate console. */
    void log(String message);
  }

You can set LogLevel as f.e. FULL and create class which wrap log4j and implements Log interface and log your logs in log(String) method, but you will get all logs as string. There is no possible to check from which level, the log comes.

EXAMPLE WRAPPER

public class ExampleLog4J implements RestAdapter.Log {
    private static final Logger logger = logger.getLogger(ExampleLogger.class)
    ExampleLog4J(){
    }
    @Override
    public void log(String message) {
        log.info("Retrofit# "+message);
    }
}

And in the place where you create RestAdapter use:

new RestAdapter.Builder().setLog(new ExampleLog4J()).
