我是 log4j 的新手,并试图在项目中使用它。由于某种原因,信息不会显示在控制台上。它仅在我将其更改为 logger.error() 时才有效。这仅发生在 userServiceImpl 类中,其他类(如控制器)很好。这是 log4j.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="false"
xmlns:log4j="http://jakarta.apache.org/log4j/">
<!-- This default ConsoleAppender is used to log all NON perf4j messages
to System.out -->
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{dd MMM yyyy HH:mm:ss} %5p %c{1} - %m%n" />
</layout>
</appender>
<!-- The root logger sends all log statements EXCEPT those sent to the perf4j
logger to System.out. -->
<root>
<level value="ERROR" />
<appender-ref ref="console" />
</root>
<logger name="com.click.heal.controller" additivity="false" >
<level value="INFO" />
<appender-ref ref="console"/>
</logger>
<logger name="com.click.heal.service" additivity="true" >
<level value="INFO" />
<appender-ref ref="console"/>
</logger>
</log4j:configuration>
