使用控制台和滚动文件appender的非常简单的log4j2属性配置文件

log4j2 配置每个人都会根据应用程序的需要更改配置。

下面是一个示例log4j2配置文件 ConsoleAppender RollingFileAppender -

status = warn
name= properties_configuration

# Give directory path where log files should get stored
property.basePath = ./log/

# ConsoleAppender will print logs on console
appender.console.type = Console
appender.console.name = consoleLogger
appender.console.target = SYSTEM_OUT
appender.console.layout.type = PatternLayout

# Specify the pattern of the logs
appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %level [%t] [%c] [%M] [%l] - %msg%n


# RollingFileAppender will print logs in file which can be rotated based on time or size
appender.rolling.type = RollingFile
appender.rolling.name = fileLogger
appender.rolling.fileName= ${basePath}app.log
appender.rolling.filePattern= ${basePath}app_%d{yyyyMMdd}.log.gz
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %level [%t] [%c] [%M] [%l] - %msg%n
appender.rolling.policies.type = Policies

# Rotate log file each day and keep 30 days worth
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = true
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.delete.type = Delete
appender.rolling.strategy.delete.basePath = ${basePath}
appender.rolling.strategy.delete.maxDepth = 1
appender.rolling.strategy.delete.ifLastModified.type = IfLastModified
# Delete files older than 30 days
appender.rolling.strategy.delete.ifLastModified.age = 30d

# Mention package name here in place of example. Classes in this package or subpackages will use ConsoleAppender and RollingFileAppender for logging         
logger.example.name = example
logger.example.level = debug
logger.example.additivity = false
logger.example.appenderRef.rolling.ref = fileLogger
logger.example.appenderRef.console.ref = consoleLogger

# Configure root logger for logging error logs in classes which are in package other than above specified package
rootLogger.level = error
rootLogger.additivity = false
rootLogger.appenderRef.rolling.ref = fileLogger
rootLogger.appenderRef.console.ref = consoleLogger

Try this out:

# Declare loggers

appenders=a_console, a_rolling
rootLogger.level=info
rootLogger.appenderRefs=ar_console,ar_rolling
rootLogger.appenderRef.ar_console.ref=StdoutAppender

appender.a_rolling.fileName=log4j2-sample.log
appender.a_rolling.filePattern=log4j2-sample-%d{yyyy-MM-dd}.log

appender.a_rolling.layout.type=PatternLayout

rootLogger.level=info

rootLogger.appenderRef.stdout.ref=STDOUT

#if you want to make package specific configuration
