Tomcat启动时log4j报错

Question

求解答

Answer 1

错误报的大意是： log4j 不能初始化 log4j.appender.info 这个配置
我知道的log4j可以通过两种方式来配置
1、xx.properties 我的一份配置如下
#log4j.rootLogger=INFO,CONSOLE,file
log4j.rootLogger=INFO,CONSOLE

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=[%d{yyyy-MM-dd HH:mm:ss}] [%c] [%p] : %m%n

log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=INFO
log4j.logger.java.sql.Statement=INFO
log4j.logger.java.sql.PreparedStatement=INFO

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=./logs/CashBuilding.log
log4j.appender.file.MaxBackupIndex=100
log4j.appender.file.MaxFileSize=5000KB
log4j.appender.file.layout = org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern = [%d{yyyy-MM-dd HH:mm:ss}] [%c] [%p] : %m%n

log4j.logger.com.ibatis=INFO
log4j.logger.org.mybatis=INFO
log4j.logger.org.springframework=INFO
log4j.logger.com.mchange.v2=INFO
log4j.logger.org.aspectj=INFO
log4j.logger.org.quartz=INFO
log4j.logger.org.apache.commons=INFO
log4j.logger.org.apache.cxf=INFO
2、xx.xml 我的一份配置如下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//LOGGER"
"log4j.dtd">
debug="true">

<appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="[%d{dd/MM/yy hh:mm:ss:sss z}] %5p %c{2}: %m%n" />
    </layout>
</appender>
<appender name="FILE" class="org.apache.log4j.RollingFileAppender">
    <param name="file" value="${user.home}/foss-framework.log" />
    <param name="append" value="true" />
    <param name="maxFileSize" value="10MB" />
    <param name="maxBackupIndex" value="100" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d [%t] %-5p %C{6} (%F:%L) - %m%n" />
    </layout>
</appender>

<!-- 下面是打印mybatis语句的配置 -->
<logger name="com.ibatis" additivity="true">
    <level value="DEBUG" />
</logger>
<logger name="org.apache.ibaties" additivity="true">
    <level value="DEBUG" />
</logger>
<logger name="Java.sql.Connection" additivity="true">
    <level value="DEBUG" />
</logger>
<logger name="java.sql.Statement" additivity="true">
    <level value="DEBUG" />
</logger>
<logger name="java.sql.PreparedStatement" additivity="true">
    <level value="DEBUG" />
</logger>
<logger name="java.sql.ResultSet" additivity="true">
    <level value="DEBUG" />
</logger>

<root>
    <level value="DEBUG" />
    <appender-ref ref="STDOUT" />
    <!-- <appender-ref ref="FILE" /> -->
</root>

/log4j:configuration

建议使用xx.xml来配置
