本文介紹了Log4j%1至log4j%2屬性文件的處理方法，對(duì)大家解決問(wèn)題具有一定的參考價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)吧！

問(wèn)題描述

有人能幫幫我嗎？

我正在從log4j%1轉(zhuǎn)到%2，但無(wú)法獲取工作屬性文件。滾動(dòng)文件vds.log未顯示

這是我以前的工作道具

# default properties to initialise log4j
log4j.rootLogger=INFO, rollingFile

# settings for specific packages
log4j.logger.com.wordnik.swagger=INFO
log4j.logger.org.apache.camel.component.servlet=INFO
log4j.logger.org.apache.camel.component.swagger=INFO
log4j.logger.org.apache.camel=INFO

# Console appender
# Uncomment when running locally
#log4j.appender.console=org.apache.log4j.ConsoleAppender
#log4j.appender.console.layout=org.apache.log4j.PatternLayout
#log4j.appender.console.layout.ConversionPattern=%d [%-15.15t] %-5p %-30.30c{1} - %m%n


log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.rollingFile.maxFileSize=10MB
log4j.appender.rollingFile.maxBackupIndex=10
log4j.appender.rollingFile.File=C:/logs/vds.log

log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.rollingFile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %m%n
log4j.appender.rollingFile.append=true

這就是我嘗試的方法，但不起作用

status = debug
name= vds

# Log files location
property.basePath = c:/logs

appender.logger.com.wordnik.swagger=INFO
appender.logger.org.apache.camel.component.servlet=INFO
appender.logger.org.apache.camel.component.swagger=INFO
appender.logger.org.apache.camel=INFO

# RollingFileAppender name, pattern, path and rollover policy
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] [%l] - %msg%n
appender.rolling.policies.type = Policies

# RollingFileAppender rotation policy
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
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 = 10
appender.rolling.strategy.delete.ifLastModified.type = IfLastModified

# Delete all files older than 30 days
appender.rolling.strategy.delete.ifLastModified.age = 30d

# Configure root logger
rootLogger.level = debug
rootLogger.appenderRef.rolling.ref = fileLogger

POM

 <!-- logging -->
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.16.0</version>
        </dependency>
        <dependency>

            <artifactId>log4j-api</artifactId>
            <version>2.16.0</version>
        </dependency>

我查看了其他答案，但都沒(méi)有幫助我。這就是我求助的原因。
有人能幫幫我嗎？提前謝謝。

推薦答案

屬性文件格式不是Log4j2.x中的默認(rèn)配置格式(僅在2.4中引入)。如果您要使用XML，log4j-1.2-api中有一個(gè)自動(dòng)配置轉(zhuǎn)換器，它可以使用以下命令將屬性文件轉(zhuǎn)換為XML：

java -cp log4j-1.2-api-2.16.0.jar:log4j-api-2.16.0.jar:log4j-core-2.16.0.jar org.apache.log4j.config.Log4j1ConfigurationConverter -i log4j.properties -o log4j2.xml

(我假設(shè)log4j-1.2-api、log4j-api和log4j-core這三個(gè)JAR都在當(dāng)前目錄中)。在您的情況下，這將為您提供：

<?xml version="1.0" ?>
<Configuration name="Log4j1">
  <Appenders>
    <RollingFile
      name="rollingFile"
      fileName="C:/logs/vds.log"
      filePattern="C:/logs/vds.log.%i">
      <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-5p %m%n" />
      <Policies>
        <SizeBasedTriggeringPolicy size="10485760" />
      </Policies>
      <DefaultRolloverStrategy max="1" />
    </RollingFile>
  </Appenders>
  <Loggers>
    <Root level="INFO">
      <AppenderRef ref="rollingFile" />
    </Root>
    <Logger
      name="org.apache.camel.component.swagger"
      level="INFO" />
    <Logger
      name="org.apache.camel.component.servlet"
      level="INFO" />
    <Logger
      name="org.apache.camel"
      level="INFO" />
    <Logger
      name="com.wordnik.swagger"
      level="INFO" />
  </Loggers>
</Configuration>

(縮進(jìn)是我的)。備注：max="1"可能是轉(zhuǎn)換器中的錯(cuò)誤。

如果您堅(jiān)持使用屬性格式，您的記錄器配置應(yīng)該如下所示：

logger.1.name=com.wordnik.swagger
logger.1.level=INFO
logger.2.name=org.apache.camel.component.servlet
logger.2.level=INFO
logger.3.name=org.apache.camel.component.swagger
logger.3.level=INFO
logger.4.name=org.apache.camel
logger.4.level=INFO

這篇關(guān)于Log4j%1至log4j%2屬性文件的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，
