• 使用以下配置将在提供的路径中创建一个日志文件，并在 14 天策略后将其删除。
• 对于包名称声明，请使用此处选定的附加程序（滚动）

创建 log4j2.properties 文件并声明所需的配置，例如：

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
