Package at.hobex.pos.logger Description

This package provides the ability to use different logger implementation.

By default the API uses the Log4J (v1.2.17) framework. If you want to use another framework or a own implemented solution it can be done by implementing the ILogger interface and set the logger in the LogManager.

Example for using an own Logging-Framework

import at.hobex.pos.logger.ILogger;
import at.hobex.pos.logger.LogManager;

public class LogManagerTest {

  private static ILogger log;
  
  public static void main(String[] args) {
    
    LogManager.setLogger(new MyLogger());
    log = LogManager.getLogger();
    log.debug("Logtest debug");
    log.info("Logtest info");
    log.warn("Logtest warn");
    log.error("Logtest error");
    log.fatal("Logtest fatal");
    
    log.debug("Logtest debug", new IllegalArgumentException("The exception message"));
    log.info("Logtest info", new IllegalArgumentException("The exception message"));
    log.warn("Logtest warn", new IllegalArgumentException("The exception message"));
    log.error("Logtest error", new IllegalArgumentException("The exception message"));
    log.fatal("Logtest fatal", new IllegalArgumentException("The exception message"));
  }
}

class MyLogger implements ILogger {

  @Override
  public void debug(Object message) {
    System.out.println("DEBUG - " + message);
  }

  @Override
  public void debug(Object message, Throwable exception) {
    System.out.println("DEBUG - " + message + " Exception: " + exception);
  }

  @Override
  public void info(Object message) {
    System.out.println("INFO  - " + message);
  }

  @Override
  public void info(Object message, Throwable exception) {
    System.out.println("INFO  - " + message + " Exception: " + exception);
  }

  @Override
  public void warn(Object message) {
    System.out.println("WARN  - " + message);
  }

  @Override
  public void warn(Object message, Throwable exception) {
    System.out.println("WARN  - " + message + " Exception: " + exception);
  }

  @Override
  public void error(Object message) {
    System.err.println("ERROR  - " + message);
  }

  @Override
  public void error(Object message, Throwable exception) {
    System.err.println("ERROR  - " + message + " Exception: " + exception);
  }

  @Override
  public void fatal(Object message) {
    System.err.println("FATAL  - " + message);
  }

  @Override
  public void fatal(Object message, Throwable exception) {
    System.err.println("FATAL  - " + message + " Exception: " + exception);
  }
