java - Log4j2 不会在 Spring Boot 中创建日志文件

问题描述

我有一个 Spring Boot 应用程序，我想使用 LOG4J2 来管理不同文件中的日志，但未创建日志文件。

我在“资源”下有一个 log4j2.properties 配置

我的日志文件配置：

name=PropertiesConfig
#output folder
property.filename=G:\\PRUEBAS
property.packagename=com.package.main
appenders=console, infoLoggerAppender, commonLoggerAppender, errorLoggerAppender
appender.console.type=Console
appender.console.name=STDOUT
appender.console.layout.type=PatternLayout
appender.console.layout.pattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
#common appender
appender.commonLoggerAppender.type=File
appender.commonLoggerAppender.name=RollingFile
appender.commonLoggerAppender.fileName=${filename}\\log.log
appender.commonLoggerAppender.layout.type=PatternLayout
appender.commonLoggerAppender.layout.pattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
#error appender
appender.errorLoggerAppender.type=RandomAccessFile
appender.errorLoggerAppender.name=RandomAccessFile
appender.errorLoggerAppender.fileName=${filename}\\error.log
appender.errorLoggerAppender.layout.type=PatternLayout
appender.errorLoggerAppender.layout.pattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
#using LevelRangeFilter to only log error levels.
appender.errorLoggerAppender.filter.threshold.type=LevelRangeFilter
appender.errorLoggerAppender.filter.threshold.minLevel=error
appender.errorLoggerAppender.filter.threshold.maxLevel=error
#info appender
appender.infoLoggerAppender.type=File
appender.infoLoggerAppender.name=LOGFILE
appender.infoLoggerAppender.fileName=${filename}\\info.log
appender.infoLoggerAppender.layout.type=PatternLayout
appender.infoLoggerAppender.layout.info=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
#using LevelRangeFilter to only log info levels.
appender.infoLoggerAppender.filter.threshold.type=LevelRangeFilter
appender.infoLoggerAppender.filter.threshold.minLevel=info
appender.infoLoggerAppender.filter.threshold.maxLevel=info
# creating only one logger, we can use this with multiple appenders.
loggers=fileLogger
# this is package name. This package and all of it's child packages will use this logger
logger.fileLogger.name=${packagename}
# logger base level
logger.fileLogger.level=debug
logger.fileLogger.appenderRefs=infoLoggerAppender, commonLoggerAppender, errorLoggerAppender
logger.fileLogger.appenderRef.infoLoggerAppender.ref=LOGFILE
logger.fileLogger.appenderRef.commonLoggerAppender.ref=RollingFile
logger.fileLogger.appenderRef.errorLoggerAppender.ref=RandomAccessFile
rootLogger.level=debug
rootLogger.appenderRefs=stdout
rootLogger.appenderRef.stdout.ref=STDOUT

我能做些什么？有人可以帮助我吗？我浪费了我最后两天的时间...

解决方案

检查 log4j2 jar 在 sprint 启动应用程序中是否可用，如果没有，则添加 maven 依赖项

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-log4j2</artifactId>
    </dependency>

创建 Log4j2.properties 文件并在资源文件夹中声明所有创建该文件

    name = ABC 
    appender.rolling.type = RollingFile
    appender.rolling.name = RollingFile
    appender.rolling.fileName = ABClog/ABCapplication.log
    appender.rolling.filePattern = ABClog/ABCapplication.%d{dd-MMM}.log
    appender.rolling.layout.type = PatternLayout
    appender.rolling.layout.pattern=%d{yyyy-MM-dd HH:mm:ss.SSS} %level [%t] [%c] [%M] [%l]- %msg%n
    appender.rolling.policies.type = Policies
    appender.rolling.strategy.type = DefaultRolloverStrategy 
    appender.rolling.strategy.action.type = Delete 
    appender.rolling.strategy.action.basepath =log 
    appender.rolling.strategy.action.condition.type = IfFileName
    appender.rolling.strategy.action.condition.glob = ABC*.log
    appender.rolling.strategy.action.ifAny.type = IfAny
    appender.rolling.strategy.action.ifAny.ifLastModified.type = IfLastModified
    appender.rolling.strategy.action.ifAny.ifLastModified.age = 14d
    appender.rolling.strategy.action.ifAny.ifAccumulatedFileSize.type = IfAccumulatedFileSize
    appender.rolling.strategy.action.ifAny.ifAccumulatedFileSize.exceeds = 200MB

    appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
    appender.rolling.policies.time.interval = 1
    appender.rolling.policies.time.modulate = true

    logger.rolling.name = com.currentobject.controller
    logger.rolling.level = debug
    logger.rolling.additivity = false
    logger.rolling.appenderRef.rolling.ref = RollingFile

将 log4j2.properties 文件的路径提供到 application.properties 文件中

    logging.config=classpath:properties/log4j2.properties
