使用 log4j2.properties 配置时，多个滚动文件附加程序不起作用

Question

我正在尝试使用属性文件配置 log4j2。我需要有多个滚动文件附加程序才能登录多个文件。但我似乎无法让多个滚动文件附加程序工作。当我只使用一个滚动文件附加程序时，它似乎工作正常并生成了相应的日志文件。在多个附加程序的情况下，只有根记录器正在生成日志文件。

我目前的配置是：-

name = PropertiesConfig
status = warn
property.log-path = E:/logs

appenders =  rolling

appender.rolling.type = RollingFile
appender.rolling.name = rolAppender1
appender.rolling.fileName = ${log-path}/log1.log
appender.rolling.filePattern = ${log-path}/$${date:yyyy-MM}/Log-%d{dd-MMM-yyyy}-log1.log
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d{yyyy-MMM-dd - HH:mm} [%-p] %C{1}.%M(%F:%L)-:%m%n
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = false

appender.rolling.type = RollingFile
appender.rolling.name = rolAppender2
appender.rolling.fileName = ${log-path}/log2.log
appender.rolling.filePattern = ${log-path}/$${date:yyyy-MM}/Log-%d{dd-MMM-yyyy}.log

我是 log4j2 的新手，对它了解不多。任何帮助，将不胜感激。

Answer 1

您需要为所有附加程序使用不同的名称。现在它只是滚动。 应该是..

appenders = rolling, rolling1, rolling2, .. so on

appender.rolling.type = RollingFile
appender.rolling1.type = RollingFile
appender.rolling2.type = RollingFile

这里rolling、rolling1、rolling2是针对不同日志的不同rolling appender。

所有滚动附加程序及其相应的其他属性等等。我刚刚选择了一个属性“类型”作为示例。

记录器也是如此。也一样。。

Answer 2

我猜你复制了一个在线教程的 sn-p 代码，这可能是关于教如何滚动 single file 而不是 multiple files。如果这是真的，请记住在您自己的代码中使用教程的代码时要更加小心。

以appender.rolling.name = rolAppender2 中的rolling 为例。 rolling term 指定此配置属于哪个附加程序，每个 Appender 必须有一个唯一的术语，而不是所有附加程序的术语 rolling。

换句话说，尽管您通过为每个 appender 使用唯一名称来区分每个 appender，但您仍然为每个 appender 使用 appender.rolling....。

因此，您的代码应如下所示：

appender.rollAppender1.type = RollingFile
appender.rollAppender1.name = rollAppender1
appender.rollAppender1.fileName = ${log-path}/log1.log
appender.rollAppender1.filePattern = ${log-path}/$${date:yyyy-MM}/Log-%d{dd-MMM-yyyy}-log1.log
appender.rollAppender1.layout.type = PatternLayout
.
.
.

appender.rollAppender2.type = RollingFile
appender.rollAppender2.name = rollAppender2
appender.rollAppender2.fileName = ${log-path}/log2.log
appender.rollAppender2.filePattern = ${log-path}/$${date:yyyy-MM}/Log-%d{dd-MMM-yyyy}-log2.log
appender.rollAppender2.layout.type = PatternLayout
.
.
.

loggers=RollLogger1,RollLogger2

logger.rolling1Logger.name = RollLogger1
logger.rolling1Logger.level = info
logger.rolling1Logger.additivity = false
logger.rolling1Logger.appenderRef.rolling.ref = rollAppender1

logger.rolling2Logger.name = RollLogger2
logger.rolling2Logger.level = info
logger.rolling2Logger.additivity = false
logger.rolling2Logger.appenderRef.rolling.ref = rollAppender2
.
.
.
