Package zeroecho.logging

package zeroecho.logging
Provides lightweight logging utilities and configuration helpers for Java Util Logging (JUL).

Overview

This package complements the standard java.util.logging framework with tools for streamlined configuration and more compact log output. It is designed for applications that prefer JUL over third-party logging frameworks but still require concise, production-ready log formatting.

Components

  • ClasspathJulConfig – loads a jul.properties configuration file from the application classpath and applies it to the global LogManager. This allows declarative setup of handlers, levels, and formatters without manual bootstrap code.
  • CompactOneLineFormatter – a formatter that produces single-line log records with timestamps, thread names, class/method context, and optional exception summaries. The output is compact enough for terminals and log aggregation systems, while still preserving diagnostic detail.

Design goals

  • Simplicity – avoid external dependencies and keep JUL setup minimal.
  • Compactness – formatters collapse whitespace and abbreviate fully qualified class names to keep logs dense but readable.
  • Safety – exception details are reduced to single-line summaries, preventing multi-line stack traces from overwhelming logs in production.

Usage example

// Automatically loads jul.properties from the classpath
new ClasspathJulConfig();

Logger logger = Logger.getLogger("demo");
logger.info("Hello world");
