java 从 log4j 迁移到 log4j2 - 属性文件配置

Migrating from log4j to log4j2 - properties file configuration

提问by Raju Rao

I have a java application which is using log4jconfigured as below.

我有一个使用log4j的 java 应用程序，配置如下。

log4j.properties

log4j.properties

log4j.rootLogger=INFO, R
log4j.appender.R = org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File = /trace.log
log4j.appender.R.Append = true
log4j.appender.R.DatePattern = '.'yyyy-MM-dd
log4j.appender.R.layout = org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern = %d{HH:mm:ss} %c{1} [%p] %m%n

I would like to migrate to log4j2 with the same configuration as above. Haven't found anything related to log4j2 properties configuration file as this support recently included.

我想使用与上述相同的配置迁移到 log4j2。没有发现与 log4j2 属性配置文件相关的任何内容，因为最近包含此支持。

Please can anyone help me out how would be my log4j2.propertiesfile with the same configuration above ?

请谁能帮我看看我的log4j2.properties文件如何与上面的配置相同？

rootLogger.level = INFO
property.filename = trace.log
appenders = R, console

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d %5p [%t] (%F:%L) - %m%n

appender.R.type = RollingFile
appender.R.name = File
appender.R.fileName = ${filename}
appender.R.filePattern = ${filename}.%d{yyyy-MM-dd}
appender.R.layout.type = PatternLayout
appender.R.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %c{1} [%p] %m%n
appender.R.policies.type = Policies
appender.R.policies.time.type = TimeBasedTriggeringPolicy
appender.R.policies.time.interval = 1

rootLogger.appenderRefs = R, console

rootLogger.appenderRef.console.ref = STDOUT
rootLogger.appenderRef.R.ref = File

You can use this to convert from Log4J.properties (v1.2) to log4j2.xml as below:

您可以使用它从 Log4J.properties (v1.2) 转换为 log4j2.xml，如下所示：

Log4j2 supports .properties files but they have changed property syntax. You can check their manual hereit covers all you need to create new configuration.

Log4j2 支持 .properties 文件，但它们更改了属性语法。您可以在此处查看他们的手册，它涵盖了创建新配置所需的所有内容。

I know it's an old issue but for the sake of history:

我知道这是一个老问题，但为了历史：

Since Log4j2 2.13.0 there is an experimentalfeature for Log4j 1 configuration files: http://logging.apache.org/log4j/2.x/manual/compatibility.html

由于 Log4j2 2.13.0 有一个Log4j 1 配置文件的实验性功能：http: //logging.apache.org/log4j/2.x/manual/compatibility.html
