log4j

问题 I try to migrate a Java8 project to Java9. The auto generated module-info.java contains an entry requires log4j; and an error is shown: log4j cannot be resolved to a module => How do I correctly include log4j as a module dependency with Java9? (I have the same issue for following dependencies: requires hibernate.core; requires hibernate.jpa.2.1.api; requires jcommander; requires junit; requires reflections; ) What I did so far: Installed Java 9.0.1 Upgraded Eclipse to Oxygen.1a Release (4.7

问题 We are using the Windows installation of Tomcat 6. By default, the log4j output for our app goes to the ${catalina.base}/logs/stdout_.log file. This log file only rolls over when we restart Tomcat, and the file name always includes the date. I would prefer it to behave like a DailyRollingFileAppender, where it renames the file when it rolls over... that way I can just open Notepad++ and see today's logs, since Notepad++ will remember that I opened that same file yesterday. :) I know I can

问题 I am having bit of an issue in logging to a file using log4j in storm . Before submitting my topology , i.e in my main method I wrote some log statements and configured the logger using : PropertyConfigurator.configure(myLog4jProperties) Now when I run my topology using my executable jar in eclipse - its working fine and log files are being created as supposed. OR When i run my executable jar using "java -jar MyJarFile someOtherOptions", i can see log4j being configured and the files are

问题 I build my "superWebApp" with the next technology stack: persistence provider - Hibernate 4.x webMvc and beans container - Spring 4.x web containter - Tomcat 7.5.x I have a task to write all logs to db. And it would be a pain to do it for each logging framework separately. That's why I need to redirect all logs to single framework and then using a DBAppender wouldn't be a problem. I was thinking about log4j2, since I use it to write logs in "superWebApp". So is there any idea how to redirect

问题 I am getting following errors on my console repeatedly log4j:ERROR Attempted to append to closed appender named [ConsoleAppender]. log4j:ERROR Attempted to append to closed appender named [FixedWindowRollingFile]. used log4j.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false"> <appender class="org.apache.log4j.rolling.RollingFileAppender" name="FixedWindowRollingFile">

问题 I am using Log4j as logging framework in a project I am working on. I have the following situation: Log4j is configured to write the logs into a log file. At some point, this log file is copied to another destination and deleted. Logging framework keeps working, but the logs are not written to the log file because it is deleted. Is there any way to tell Log4j to recreate the file and keep writing the logs into the log file. Best regards, Rashid 回答1: I study the source of log4j and find log4j

问题 I've set my log4j.properties file to this configuration below log4j.rootLogger=INFO, CATALINA # Define all the appenders log4j.appender.CATALINA=org.apache.log4j.DailyRollingFileAppender log4j.appender.CATALINA.File=${catalina.base}/logs/catalina. log4j.appender.CATALINA.Append=true log4j.appender.CATALINA.Encoding=UTF-8 # Roll-over the log once per day log4j.appender.CATALINA.DatePattern='.'yyyy-MM-dd'.log' log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout log4j.appender

问题 I have a Tomcat 6 server with a lot of web application directories and I have set up Log4J. It works for all application directories which are not deployed via a war file. The current configuration looks like this: /tomcat/lib/log4j.properties # Define all the appenders log4j.appender.root=org.apache.log4j.RollingFileAppender log4j.appender.root.File=${catalina.base}/logs/tomcat.log log4j.appender.root.Append=true log4j.appender.root.MaxFileSize=1MB log4j.appender.root.MaxBackupIndex=5 log4j

问题 I am using jose4j in a java application that I am working on. It is a json web token library, and I've found that putting the package name inside my log4j config file does nothing to quiet the (many) debug logging messages that I am seeing from this thing. Here's my relevant log4j config section <Root level="debug"> <AppenderRef ref="Console"></AppenderRef> </Root> <Logger name="org.jose4j" level="warn" additivity="false"> <AppenderRef ref="Console"></AppenderRef> </Logger> So, I essentially

问题 I am currently tasked with changing all occurrences of LOG4J to SLF4J including logback when necessary. I already managed converting all the old log4j.xml to logback.xml and to force the usage of logback appenders, however, I just discovered a line in the code that I can't translate to slf4j / logback just yet. Googling the issue didn't turn up anything usable, so I hope that some of you can help me here. The code line is: for ( final Enumeration e = LogManager.getLoggerRepository()
