appender

问题 I'm tried to create multiple log files of different content with log4j. This is my log4j.properties file # Direct log messages to a log file log4j.appender.file=org.apache.log4j.RollingFileAppender log4j.appender.file.File=/home/dhanushka/Documents/log4j.log log4j.appender.file.MaxFileSize=1MB log4j.appender.file.MaxBackupIndex=1 log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n log4j.appender.testng=org

问题 I want my application to log to two files: first one, already exists, and will log everything. The second one only will log conditionally. This is my log4j.properties: log4j.rootCategory=DEBUG, FILE log4j.logger.es.vf.pegaso=DEBBUG log4j.logger.org=ERROR log4j.logger.org.hibernate=ERROR log4j.logger.org.displaytag=ERROR log4j.logger.es.vf.pegaso.common.form.el.ElEvaluator=ERROR log4j.logger.es.vf.pegaso.common.util.csvreader.CsvReaderElEvaluator=ERROR log4j.appender.FILE=org.apache.log4j

问题 I wrote a custom appender JTableAppender which implements ILoggingEvent . This appender has a public setter setModel(..) to assign a table model to the appender, so I can manipulate the model in doAppend() . The JTableAppender is configurated in an xml file, where I named it TABLE: <appender name="TABLE" class="blabla.jgwf.test.logger.JTableAppender"> <!-- encoders are by default assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder --> <encoder> <pattern>%d{HH:mm:ss.SSS} [

问题 I was trying to find out how to use JMSQueueAppender but there were no proper instructions on how to do the same. After bit trial and error, i was able to configure the JMSQueueAppender using log4j (with my own JMSQueueAppender class). Below is the configuration in log4j.properties file. log4j.rootLogger=INFO, stdout, jms ## Be sure that ActiveMQ messages are not logged to 'jms' appender log4j.logger.org.apache.activemq=INFO, stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j

问题 I am able to create log files using FileAppender, RollingFileAppender,etc., My Problem is that the logs are written as plain text that anyone can read, but I want to register my logs as Binary Files that are not human readable. Can anyone help me with the suggestion to create a Binary log file for an example code. 回答1: Its not such a good Idea to do what you wrote, but if you really need to, write an own appender like this: package de.steamnet.loggingUtils; import java.io

问题 In Log4j there was a WriterAppender that made it possible to write the logs to a Writer . I need the same functionality in Log4j2 , but I haven't found an option to do this yet. Does anyone know how to achieve the same with Log4j2 ? 回答1: If there is not an existing appender that serves your needs, create a custom appender plugin. I put together a quick example. package com.logging; import org.apache.logging.log4j.core.Filter; import org.apache.logging.log4j.core.Layout; import org.apache

问题 I'd like to start using Chainsaw v2. There is almost no information about it. I've found only this , but links cannot be opened, so it isn't clear. I use socketAppender: log4j.rootLogger=DEBUG, server log4j.appender.server=org.apache.log4j.net.SocketAppender log4j.appender.server.Port=4712 log4j.appender.server.RemoteHost=localhost log4j.appender.server.ReconnectionDelay=10000 I created file log4j.xml <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration > <log4j:configuration

问题 I have a log file currently configured to roll over every hour. When it is first created it is called logfile.log, and once it rolls over it is renamed to logfile.log.YYYY-MM-DD-HH. What I would like is for the log file to be created immediately using the logfile.log.YYYY-MM-DD-HH naming convention as opposed to logfile.log. Any ideas? 回答1: Take a look at this post: http://tecbites.blogspot.com/2006/10/log4j-tipps-and-tricks.html It discusses the use of DatedFileAppender described here: http:

问题 I have spent all day trying to solve the logging problem I'm having with log4j in a webapp. No matter what I do, I cannot get rid of the following: log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
