【问题描述】：
我有一个使用 log4j2 进行日志记录的 maven 项目。我想覆盖 RootLogger 的模式。
这是我的 log4j2.properties 文件：
status = debug
name= properties_configuration
# Give directory path where log files should get stored
property.basePath = ./log/
appenders =console, rolling
# ConsoleAppender will print logs on console
appender.console.type = Console
appender.console.name = consoleLogger
appender.console.target = SYSTEM_OUT
appender.console.layout.type = PatternLayout
# Specify the pattern of the logs
appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %level [%t]
[%c] [%M] [%l] - %msg %xEx %n
# RollingFileAppender will print logs in file which can be rotated based on
time or size
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]
[%c] [%M] [%l] - %msg %xEx %n
appender.rolling.policies.type = Policies
# Rotate log file each day
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 = 1
appender.rolling.strategy.delete.ifLastModified.type = IfLastModified
# Delete files older than 30 days
appender.rolling.strategy.delete.ifLastModified.age = 30d
logger.example.name = com.parohia
logger.example.level = debug
logger.example.appenderRef.rolling.ref = fileLogger
logger.example.appenderRef.console.ref = consoleLogger
rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = consoleLogger
这是我用于 log4j 的 pom.xml 文件：
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.8.2</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.8.2</version>
</dependency>
我这样称呼我的记录器：
private final Logger logger = LogManager.getLogger(PersoaneController.class);
try{
.....
}
catch(Exception ex){
logger.error(ex.getMessage(),ex);
}
我的配置有 2 个问题。首先是根记录器不使用我的consoleAppender（警告等以默认格式出现）并且在记录错误时我只得到第一行而不是整个堆栈跟踪）。

您的配置文件似乎无效，例如布局模式为 2 行，cmets 为 2 行。通过这种方式，第二行实际上变得无效
