log4j第二个记录器错误

为什么我的第二个记录器出现错误，而第一个没有

错误：

log4j:WARN No appenders could be found for logger (StatQueryDobadoCategory).
log4j:WARN Please initialize the log4j system properly.

这是log4j.properties：

log4j.category.ThingsPerMinuteGraphCategory=DEBUG, ThingsPerMinuteGraphAppender
log4j.appender.ThingsPerMinuteGraphAppender=org.apache.log4j.RollingFileAppender
log4j.appender.ThingsPerMinuteGraphAppender.File=./logs/ThingsPerMinuteGraph.log
log4j.appender.ThingsPerMinuteGraphAppender.MaxFileSize=20MB
log4j.appender.ThingsPerMinuteGraphAppender.MaxBackupIndex=5
log4j.appender.ThingsPerMinuteGraphAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.ThingsPerMinuteGraphAppender.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss.SSS} - %m
log4j.additivity.ThingsPerMinuteGraphCategory=false

log4j.category.StatQueryDobadoCategory=DEBUG, StatQueryDobadoAppender
log4j.appender.StatQueryDobadoAppender=org.apache.log4j.RollingFileAppender
log4j.appender.StatQueryDobadoAppender.File=./logs/StatQueryDobadoCategory.log

log4j.additivity.StatQueryDobadoCategory=false

该库似乎无法访问log4j.properties。

如果只为java项目使用log4j，请将属性文件放入源文件夹中

<context-param>
<param-name>
log4jConfigLocation
</param-name>
<param-value>
/WEB-INF/log4j.properties
</param-value>
</context-param>
如果您对j2ee项目使用log4j，比如spring+hibernate，请将log4j.properties放入WEB-INF文件夹，并在项目的属性文件中设置属性文件的路径

<context-param>
<param-name>
log4jConfigLocation
</param-name>
<param-value>
/WEB-INF/log4j.properties
</param-value>
</context-param>


log4jconfig

/WEB-INF/log4j.properties
