Question

我想要一个带有控制台的log4j2属性文件配置和一个使用log4j2的滚动文件appender，它可以用于不同的应用程序。日志配置应该旋转生产环境中的日志。

Answer 1

我认为没有针对日志记录或log4j2配置的行业标准。每个人都根据应用程序的需要更改配置。

以下是一个示例log4j2配置文件ConsoleAppender和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

Answer 2

如果您只需要使用控制台附加程序，这是最简单的配置。

using (var webClient = new WebClient())
{
    webClient.Headers.Add(HttpRequestHeader.Accept, "application/json");
    webClient.Headers.Add(HttpRequestHeader.AcceptEncoding, ": gzip, deflate, br");

    var json = webClient.DownloadString("https://stats.nba.com/stats/teamyearbyyearstats?TeamID=1610612746&LeagueID=00&PerMode=Totals&SeasonType=Regular%20Season");
    Console.WriteLine(json);
}

Try this out:

# Declare loggers
name=LoggingConfig
appenders=a_console, a_rolling
rootLogger.level=info
rootLogger.appenderRefs=ar_console,ar_rolling
rootLogger.appenderRef.ar_console.ref=StdoutAppender
rootLogger.appenderRef.ar_rolling.ref=DailyRollingAppender

# Console logger
appender.a_console.type=Console
appender.a_console.name=StdoutAppender
appender.a_console.layout.type=PatternLayout
appender.a_console.layout.pattern=%d{ISO8601} [%t] %-5p (%F\:%L) - %m%n

# File logger
appender.a_rolling.type=RollingFile
appender.a_rolling.name=DailyRollingAppender
appender.a_rolling.layout.pattern=%d{ISO8601} [%t] %-5p (%F\:%L) - %m%n

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

appender.a_rolling.layout.type=PatternLayout
appender.a_rolling.policies.type=Policies
appender.a_rolling.policies.time.type=TimeBasedTriggeringPolicy
appender.a_rolling.policies.time.interval=1

使用Console和Rolling File appender的非常简单的log4j2属性配置文件
