slf4j

问题 I want to get rid of this lot... public void info(String msg); public void info(String format, Object arg); public void info(String format, Object arg1, Object arg2); public void info(String format, Object[] argArray); ...and replace it with this one... public void info(String format, Object ... args); ...so that my logging syntax doesn't have to change depending on the number of arguments I want to log. There seems to be lots of discussion and work around it, but where is it? Or should I

问题 I need to poll the JVM memory stats of my running application on a regular basis. I'm running a service that does this and writes the stats to the root Logger (I don't have much control over Root Logger usage or not). What I want to do is route just these logging messages to a single appender. This appender should only process logging messages from this one class, and not from any other class. The other appenders shouldn't receive the messages from this one class. So far I have the log

问题 I'm not sure the term "bombing" is the right one. By bombing, I mean a log happening many times with the same content (message and args). For example, a denial of service attach might cause a log warning that an unauthenticated user is trying to access some API. log: [03-29 11:26:01.000] missing token [03-29 11:26:01.001] missing token [03-29 11:26:01.005] missing token ... overall 100000 times The problem I'm trying to tackle is preventing the log from being very large. Size is a problem.

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 My java project has dependencies with different SLF4J versions. How do I suppress the annoying warnings? SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:xyz234/lib/slf4j- log4j12-1.5.8.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:xyz123/.m2/repository/org/slf4j/slf4j-log4j12 /1.6.0/slf4j-log4j12-1.6.0.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an

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'm using slf4j logging facade over the jdk built in logger. I'm confused how to set the logging level using a ConsoleHandler for SLF4J. public Class foo(){ Logger log = Logger.getLogger(foo.class()) //logger from SLF public void run(){ log.info("info") } private static void main(String[] args){ ConsoleHandler con = new ConsoleHandeler(); //from java.util.logging con.setLevel(Level.OFF) run() } } >INFO: info Shouldn't the info be turned off? I didn't want to set up a logging properties file

问题 Obviously it's possible to write my own appender in Logback which sends the output to an IConsole . Is there a simpler way? 回答1: Can't you just use Eclipse plugin for logback? 来源： https://stackoverflow.com/questions/8026444/how-to-show-slf4j-logs-of-an-rcp-application-in-within-the-application

问题 I'm using slf4j with the following configuration <appender name="FILE" class="ch.qos.logback.core.FileAppender"> <file>${CATALINA_HOME}/logs/GO.log</file> <encoder> <pattern>%date %-5level [%thread] - [%logger] - %msg%n</pattern> </encoder> </appender> <root level="DEBUG"> <appender-ref ref="stdout"/> <appender-ref ref="FILE"/> </root> If I start tomcat using startup.bat I can see the GO.log and the catalina.{date}.log get generated. If I start tomcat from Eclipse no luck. I tried defining
