Log4j2 - Hello World!

Introduction

本篇文章主要針對Log4j2設定的基本結構做介紹，讓大家可以快速進入Log4j2的世界。Log4j2的configuration file提供了XML、JSON、YAML與properties設定的方式，為了利於Log4j1轉換到Log4j2的格式銜接，我選擇了properties格式做介紹。

Example

# part1  Top level定義
status = warn
name= CommonLogSettingForUnitTests
rootLogger = DEBUG, CONSOLE
 
# part2 Appender定義
appender.console.type = Console
appender.console.name = CONSOLE
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{mm:ss,SSS}|%5p[%t] (%F:%M:%L) %m %n
appender.console.filter.threshold.type = ThresholdFilter
appender.console.filter.threshold.level = ALL
 
# part3 Logger定義
logger.reflections = DEBUG, CONSOLE
logger.reflections.name = org.reflections.Reflections
logger.reflections.additivity = false
 
logger.default = DEBUG, CONSOLE
logger.default.name = org.tonylin.practice
logger.default.additivity = false
