错误:“未提供名称属性"-用于log4j2.properties定制 [英] Error:'No name attribute provided'- for log4j2.properties customisation

问题描述

我正在自定义log4j2.properties以在所需位置生成日志文件. 这样做时，我收到以下错误.

I am customising log4j2.properties to generate log file in desired location. While doing that I am getting the following error.

我的log4j2.priperties文件

推荐答案

• 使用以下配置将在提供的路径中创建一个日志文件，并将在14d策略后将其删除.
• 对于软件包名称声明，请使用此处选择的附加程序(滚动)

创建log4j2.properties文件并声明所需的配置，例如:

Create log4j2.properties file and declare the required configurtaion,like:

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

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
