log4j2

问题 I am trying to use properties in a log4j2.yaml. The equivalent XML is this. <Configuration> <Properties> <Property name="log-path">logs</Property> <Property name="archive">${log-path}/archive</Property> </Properties> <Appenders> . . . I tried this. Configutation: name: Default properties: property: name: log-path value: "logs" name: archive value: ${log-path}/archive Appenders: But the properties are not getting picked. For example, the following code creates a ${log-path} folder to store a

问题 I want to dynamically create an appender and add it to a logger. However, this seems not to be possible with slf4j. I can add my appender to a log4j logger but then I fail to retrieve the logger with the slf4j LoggerFactoy. What I want to do: I create a test class (not a jUnit test) and pass a logger in the constructor for the test class to use. Every instance of the test class needs it's own logger and appender that saves the log so it can be later used in an HTML report. What I tried (for

问题 There are examples for log4j2 syslog for adding priority to log with xml using key, value but with log4j.properties files we can't add = symbol to value and I haven't any example to set LoggerFields for setting priority with RFS5454 format. This one is close LoggerFields for Syslog (output log priority and stack trace) None of the below works for LoggerField: appender.sumo_syslog.loggerFields={'key' : 'priority', 'value' : '%p'} or appender.sumo_syslog.loggerFields=[{'key' : 'priority',

问题 I am using Netty 4.1.6. Is it possible to set netty using log4j2 as internal logger? Eclipse prompt me that the following statement is depreciated. InternalLoggerFactory.setDefaultFactory(new Log4J2LoggerFactory()); Would you tell me how to do so? 回答1: Thanks Ferrybig for the tip. I am elaborating on how to do this on log4j2. Before you do the Netty server bootstrap, insert this line above. InternalLoggerFactory.setDefaultFactory(Log4J2LoggerFactory.INSTANCE); ServerBootstrap b = new

问题 As a complete beginner, how do I set up Log4j2 (in Netbeans) to log some messages to the console and others into a file? (I only found guides for older versions, which got me into trouble because the XML changed. Basically, I’m updating what was done in this thread, because I thought it was a great idea but some tips were missing) 回答1: You will need to download this archive of binaries Add “log4j-api-2.8.1.jar” and “log4j-core-2.8.1.jar” to your project. (in NetBeans: File -> Project

问题 I just converted from log4j to log4j2, using an xml config file. Everything is working except that I can't seem to set the path of my log files using a properties file. This is a Spring MVC app and I have a filedirs.properties file located in the src/main/resources folder along with the log4j2.xml, i18n message and other properties files. It has a simple entry: logs=G:/web/logs/ .` I've looked through other posts and am just not getting how to configure log4j2 correctly. Here's what I've have

问题 After upgrading Karaf from 2.2.11 to 4.0.3 with log4j2 support and running load tests of our Karaf based application, Karaf unexpectedly starts shutdown process. We increased most of memory options but it did not help. No info in logs - just "Stopping blueprint extender" and "Unregistering bundles...". Above these messages there was debug info from my bundles. In manifest files of our bundles old OSGI container is used (org.osgi.framework;version="1.3.0"). This occurs for single threaded

问题 I need to implement multiple loggers and multiple appenders. My log4j2.xml looks like below: <Appenders> <RollingFile name="SYSTEM_LOGGER" fileName="${logging.folder}System.log" filePattern="${ARCHIVE}System.log.%d{dd MMM yyyy HH:mm:ss.SSS}.gz"> <PatternLayout> <Pattern>${PATTERN}</Pattern> </PatternLayout> <Policies> <TimeBasedTriggeringPolicy interval="10" modulate="true"/> <SizeBasedTriggeringPolicy size="4 MB" /> <DefaultRolloverStrategy max="50"/> </Policies> </RollingFile> <Appenders>
