log4j2

问题 I am using log4j2 with xml configuration. I want to log all the JSON created by restTemplate How can I configure it in log4j2 xml configuration file to log these? 回答1: If your RestTemplate uses apache http client, your log4j2.xml configuration could look like this: <Logger name="org.springframework.web.client" level="DEBUG" additivity="false"> <AppenderRef ref="APP" level="DEBUG"/> </Logger> <Logger name="org.apache.http.wire" level="DEBUG" additivity="false"> <AppenderRef ref="APP" level=

问题 Hopefully a simple question but My google foo is failing me - I've got a maven project where we're using SLF4J with Log4J 1.2 bindings. We now want to move to Log4j 2 particularly for the performance improvement - however, I can't for the life of me find the maven dependency for the log4j 2.0 binding. I've found some notes at http://logging.apache.org/log4j/2.x/log4j-slf4j-impl/ but no mention of any dependency info. I'm also slightly confused by the fact there's apparently two ways to put

问题 There is now some days that I'm spending on java logger: log4j2 The approach is relatively easy if you decide to work on the basis with an .xml file. But in case you want to create the configuration by code, and adapt through java, it is a bit more complicated. Below the code I could manage for now. I didn't succeed to reconfigure the log level Each time depth is stopping on error level 2017-03-15 23:24:27,248 [main] ERROR: This is Logger for 1 Error 2017-03-15 23:24:27,256 [main] ERROR: This

问题 I'm trying to create a conditional statement in my log4j2.xml file and it does not seem to accept any of the conditional formatting. I've tried various options such as xslt etc. and it doesn't seem to work. Any help here would be great. My intention is to create separate paths for logging, based on the operating system. I see that the appender error is because the MyRollingLog value has not be set. However it's the CLASS_NOT_FOUND error that I'm not able to solve and the the invalid element .

问题 I'm trying to configure log4j v2 with mysql, but it returns this error: 2014-08-01 15:35:24,819 ERROR Unable to write to database [jdbcManager{ description=databaseAppender, bufferSize=0, connectionSource=factory{ public static java.sql.Connection it.prisma.presentationlayer.webui.ConnectionFactory.getDatabaseConnection() }, tableName=logs, columns=[ { name=message, layout=%message, literal=null, timestamp=false } ] }] for appender [databaseAppender]. org.apache.logging.log4j.core.appender

问题 I am in the process of migrating my application from log4j 1.2 to log4j 2.0 I have existing code: Enumeration appenders = logger.getAllAppenders(); . . . fileBackupIndex = rollingFileAppender.getMaxBackupIndex(); In log4j 2.0 I could not find way to replace above java code. How to get list of all appenders and how to get the max value defined for RollingFile appender programatically? 回答1: With log4j2, there is a separation between API and CORE. This allows the team to make changes to the

问题 I have created and run a stand-alone Java program that logs via Log4j2 using Slf4j . The logging worked as expected. I then added this functionality to an existing (and working) OpenShift Java web application that I am developing in an Eclipse IDE . I added the following dependencies to pom.xml <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.21</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core<

问题 I recently migrated from log4j to log4j2 on my tomcat6 server. The problem is that my rolling files that are deleted are remaining open forever and hence the disk space is not being freed. i used this command "sudo /usr/sbin/lsof | grep deleted" to check on the open deleted files. I don't seem to understand how to close those files without restarting the tomcat server. Some of these logs are being deleted by cron jobs. while a lot of them are being deleted via logrotate. ... <Appenders>

问题 I'm using log4j 2 and RollingFile appender: <RollingFile name="mylog" fileName="mylog.log" filePattern="mylog.log.%d{yyyy-MM-dd}.log"> <PatternLayout> <pattern>[%d] [%-5p] [%-8t] %F:%L %m%n</pattern> </PatternLayout> <Policies> <TimeBasedTriggeringPolicy interval="1"/> </Policies> </RollingFile> The log files do get renamed daily. But the Javadoc of FileRenameAction class indicates there is an option renameEmptyFiles which is false by default so if a day's log is empty it deletes it instead

问题 I have the following log4j2 configuration <?xml version="1.0" encoding="UTF-8"?> <Configuration status="TRACE"> <Appenders> <RollingRandomAccessFile name="SQLTiming" fileName="${web:rootDir}/log/SQLTiming.log" filePattern="${web:rootDir}/log/SQLTiming-%d{yyyy-MM-dd}.log"> <PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %logger{2} - %msg%n" /> <Policies> <TimeBasedTriggeringPolicy /> </Policies> </RollingRandomAccessFile> <Console name="CONSOLE"> <PatternLayout pattern="%d{HH:mm:ss.SSS} %
