使用Log4J 1. *，如何将两个包写入两个单独的文件？ [英] Using Log4J 1.*, how can I write two packages to two separate files?

问题描述

我有以下两个套餐：

com.mycorp.project.first

com.mycorp.project.second

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，从另一个包写入第二个文件。我不希望他们混在一起。

I'd like to configure Log4J (SLF4J) to write the logs from one package to one file, and from the other package to a second file. I do not want them to be mixed in together.

要清楚，这是一个项目/一个进程正在运行。

To be clear, this is one project/one process running.

我已经尝试过滤和记录器，但它们似乎被log4j忽略。这两个文件总是完全相同。

I've tried filtering and with loggers but they seem to be ignored by log4j. Both files are always identical.

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。

Thank you for the answers so far, this is what I've got and it's not working. Both output files are identical.

<configuration debug="true">
<contextName>dev</contextName>

<appender name="FIRST_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>A:/dev/LogTesting/logs/first.log</file>
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
        <level>INFO</level>
    </filter>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>A:/dev/LogTesting/logs/first.%d{yyyyMMdd}%d{_HHmmss,aux}.log.gz</fileNamePattern>
    </rollingPolicy>
    <encoder>
        <pattern>%d{MMM dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>

    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">

推荐答案

试试这是属性文件的示例：

Try this is the example of properties file:

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

或这个用于XML（仅突出显示重要部分）：

or this for XML (only highlight important part):

<!-- 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>
