Question

我有以下两个包：

com.mycorp.project.first
com.mycorp.project.second

我想配置Log4J（SLF4J）将日志从一个包写入一个文件，并从另一个包写入第二个文件。我不希望他们混在一起。

要清楚，这是一个项目/一个进程正在运行。

我尝试过滤和使用记录器，但它们似乎被log4j忽略了。两个文件总是完全相同。

编辑：感谢您到目前为止的答案，这就是我所拥有的并且它无法正常工作。两个输出文件都是相同的。

<configuration debug="true">

    <file>A:/dev/LogTesting/logs/first.log</file>

Answer 1

尝试这是属性文件的示例：

log4j.rootLogger=DEBUG, CONSOLE
# Each package has different appender name     
log4j.logger.com.mycorp.project.first=DEBUG, FIRST
log4j.logger.com.mycorp.project.second=DEBUG, SECOND

log4j.appender.FIRST=org.apache.log4j.RollingFileAppender
log4j.appender.FIRST.File=./first.log
log4j.appender.FIRST.layout=org.apache.log4j.PatternLayout

log4j.appender.SECOND=org.apache.log4j.RollingFileAppender
log4j.appender.SECOND.File=./second.log
log4j.appender.SECOND.layout=org.apache.log4j.PatternLayout

或者这个用于XML（仅突出显示重要部分）：

<!-- FIRST appender definition -->
<appender name="FIRST" class="org.apache.log4j.FileAppender">
    ...
</appender> 

<!-- SECOND appender definition -->
<appender name="SECOND" class="org.apache.log4j.FileAppender">
    ...
</appender>

<!-- logger package com.mycorp.project.first -->
<logger name="com.mycorp.project.first">
    <level value="DEBUG" />
    <appender-ref ref="FIRST"/>
</logger>

<!-- logger for package com.mycorp.project.second -->
<logger name="com.mycorp.project.second">
    <level value="DEBUG" />
    <appender-ref ref="SECOND"/>
</logger>

Answer 2

创建两个appender LOG1和LOG2，每个日志文件一个。之后，在log4j配置文件中引用这些appender定义两个类别（每个包一个）。

<category name="com.mycorp.project.first" additivity="true">
    <priority value="TRACE"/>
    <appender-ref ref="LOG1"/>
</category>

Appender2

<category name="com.mycorp.project.second" additivity="true">
    <priority value="TRACE"/>
    <appender-ref ref="LOG2"/>
</category>

Answer 3

将动态文件路径.in log4j.properties

放入

log4j.appender.FILE.File=${file.name}

在java设置文件路径System.setProperty("file.name", FILEPATH);

中

Answer 4

您只需指定2个appender，但为两者提供相同的输出日志文件名。

#same appender for both packages
log4j.logger.package1=INFO,MyCommonLogger    
log4j.logger.package2=INFO,MyCommonLogger

log4j.appender.MyCommonLogger=org.apache.log4j.DailyRollingFileAppender
log4j.appender.MyCommonLogger.layout=org.apache.log4j.PatternLayout
log4j.appender.MyCommonLogger.layout.ConversionPattern=%t %d{MM/dd/yy HH:mm:ss} %x %-5p %c %M - %m%n

#single log file for logs from both packages
log4j.appender.MyCommonLogger.File=/somewhereonserver/log/mysinglelogfile.log

使用Log4J 1. *，如何将两个包写入两个单独的文件？
