我正在尝试使用特定模式编写log4j2日志:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout charset="UTF-8"
pattern="%d{HH:mm:ss.SSS} ${main:-jobId} %-5.-5level %-25.-25c{1}%-25.-25method(%5.5line) - %msg%n" />
</Console>
<RollingFile name="LogFile" fileName="${sys:logFile}"
filePattern="${sys:logFile}-%d{MM-dd-yyyy}-%i.log.gz">
<PatternLayout charset="UTF-8"
pattern="%d{yyy-MM-dd HH:mm:ss.SSS} ${main:-jobId} [%-30.-30t] %-5.-5level %-25.-25c{1}%-25.-25method(%5.5line) - %msg%n" />
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="100 MB" />
</Policies>
</RollingFile>
</Appenders>
<Loggers>
<Root level="trace">
<AppenderRef ref="LogFile" level="debug" />
<AppenderRef ref="Console" level="info" />
</Root>
</Loggers>
</Configuration>
我传递了一些参数-o abc -d def -jobId 1234 -DlogFile /usr/lib/logpath.log这适用于系统参数,但日志打印为:
15:33:34.889 jobId INFO Test main ( 74) - -b
15:33:34.890 jobId INFO Test main ( 74) - -o
15:33:34.890 jobId INFO Test main ( 74) - account
15:33:34.890 jobId INFO Test main ( 74) - document
15:33:34.890 jobId INFO Test main ( 74) - -d
15:33:34.891 jobId INFO Test main ( 74) - rest
15:33:34.891 jobId INFO Test main ( 74) - -l
15:33:34.891 jobId INFO Test main ( 74) - 100
15:33:34.891 jobId INFO Test main ( 74) - -skipmd
15:33:34.891 jobId INFO Test main ( 74) - -db
15:33:34.891 jobId INFO Test main ( 74) - -jobId
15:33:34.891 jobId INFO Test main ( 74) - 1234
main中的代码以:
开头public static void main(String[] args) throws Exception
{
MainMapLookup.setMainArguments(args);
for (String s : args)
logger.info(s);
...
}
我尝试过使用基于索引的参数,但它确实有用。但是,主参数查找似乎不起作用。我在这里错过了什么吗?
也许是一个偏离主题的问题,在日志记录中对主要参数处理系统变量的合法用例是什么?
答案 0 :(得分:1)
它不起作用的原因是因为MainMapLookup之间的格式与StrSubstitutor默认值分隔符之间存在冲突。
$ {main:-jobId} 被解析为Property main 或 jobId
这是此处报告的已知错误:https://issues.apache.org/jira/browse/LOG4J2-1013
