Spring Boot和Log4j问题

Question

我的log4j设置如下。当我作为引导应用程序运行时，日志将正确写入控制台，debug.log和dump.log中。下面是我在我的程序编写登录控制台的debug.log

static final Logger LOG = Logger.getLogger(EnvironmentLoader.class);  
LOG.info("blah blah!"); 

下面要做的是什么，我在我的程序做写入日志中dump.log

private static final Logger DUMP_LOG = Logger.getLogger("dumpLogger"); 
DUMP_LOG.info("blah blah!"); 

两个工作正常，如果我作为Spring Boot App运行。如果我将它打包为war并在tomcat中运行，DUMP_LOG在dump.log中正确写入，但LOG未在控制台或debug.log中写入。我想知道为什么。

log4j.rootLogger=INFO, stdout, debugLog 

log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=%d %-5p %c.%M:%L - %m%n 
log4j.appender.stdout.Target=System.out 

log4j.appender.debugLog=org.apache.log4j.DailyRollingFileAppender 
log4j.appender.debugLog.Append=true 
log4j.appender.debugLog.DatePattern='.'dd-MM-yyyy 
log4j.appender.debugLog.File=${catalina.base}/logs/debug.log 
log4j.appender.debugLog.MaxFileSize=10MB 
log4j.appender.debugLog.encoding=UTF-8 
log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout 
log4j.appender.debugLog.layout.ConversionPattern=%d %-5p %c.%M:%L - %m%n 

log4j.category.debugLogger=DEBUG, debugLog 
log4j.additivity.debugLogger=false 

log4j.appender.dumpLog=org.apache.log4j.DailyRollingFileAppender 
log4j.appender.dumpLog.Append=true 
log4j.appender.dumpLog.DatePattern='.'dd-MM-yyyy 
log4j.appender.dumpLog.File=${catalina.base}/logs/dump.log 
log4j.appender.dumpLog.MaxFileSize=10MB 
log4j.appender.dumpLog.encoding=UTF-8 
log4j.appender.dumpLog.layout=org.apache.log4j.PatternLayout 
log4j.appender.dumpLog.layout.ConversionPattern=%d - %m%n 

log4j.category.dumpLogger=DEBUG, dumpLog 
log4j.additivity.dumpLogger=false
