log4j

问题 I added following configuration in my jboss AS'S CONFIG directory Entry in jboss-log4j.xml file <appender name="YYY" class="org.apache.log4j.FileAppender"> <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"></errorHandler> <param name="Append" value="false"/> <param name="File" value="${jboss.server.home.dir}/log/app1.log"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/> </layout> </appender> <category

问题 What I want to do is create custom log Levels (for example SentLevel, ReceivedLevel and ReadLevel) and store the messages logged using them in separate files. Let me explain myself more clearly, with an example. Each LOC should be placed in separate LOG files: logger.log(ResultadosEnviadosLevel.RESULTADOS_ENVIADOS, "sent data :)"); logger.log(ResultadosRecibidosLevel.RESULTADOS_RECIBIDOS, "received data :-)"); logger.log(CustomLevel.ACCION, "action!!"); Content of today-sent: sent data :)

问题 I am pretty new to using the Kafka stream. In a particular requirement I have to push my log4j logs directly to Kafka topic. I have a standalone kafka installation running on centos and i have verified it with the kafka publisher and consumer clients. Also i am using the bundled zookeeper instance. Now i have also created a standalone java app with log4j logging enabled. Also i have edited the log4j.properties file as below - log4j.rootCategory=INFO log4j.appender.file=org.apache.log4j

问题 a very good day to all . I am asking a question , out of curisioty , may be this seem to be a foolish question also . This is my log4j.properties file for a Application which will be in production very soon . log4j.rootCategory=Info, A1 A1 is a DailyRollingFileAppender log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender log4j.appender.A1.file=D:/MyWEBLogs/MyWEB.log log4j.appender.A1.datePattern='.'yyyy-MM-dd log4j.appender.A1.append=true log4j.appender.A1.layout=org.apache.log4j

问题 I tried to follow this example, but when I copied this class to my project I failed to run it. I've no idea how my imports should look like, because eclipse suggests a lot of options. I tried import javax.jms.Connection; import javax.jms.Message; import javax.jms.MessageConsumer; import javax.jms.MessageListener; import javax.jms.Session; import org.apache.activemq.ActiveMQConnectionFactory; import org.apache.activemq.command.ActiveMQObjectMessage; import org.apache.log4j.Logger; import org

问题 Almost in every project I use either Log4j or Slf4j with logback to log events and almost everywhere I have to write something like if (log.isDebugEnabled()) { log.debug("I'm here doing this stuff"); } Sometimes you don't see actual method logic with all these logging code. I cannot remove log.isDebugEnabled() checks because even if I use Slf4j with {} feature some log information might be calculated and dropped if debug (or whatever level) is not enabled. log.debug("Here is the data: {}",

问题 I have a log4j.properties file in my current directory that specifies some things to log at DEBUG level, and everything else as INFO: log4j.rootLogger=WARN, stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=[%5p] %d{mm:ss} (%F:%M:%L)%n%m%n%n log4j.logger.com.xcski=DEBUG log4j.logger.org.apache.nutch.protocol.http=DEBUG log4j.logger.org.apache.nutch.fetcher.Fetcher=DEBUG And I

问题 I am working a number of projects that are using Dropwizard 0.8.2 with sfl4j-api 1.7.12 for logging. Our chosen implementation for slf4j is slf4j-log4j12, but we are having a problem with multiple implementations present in the project. When trying to run it, it complains that multiple SLF4J bindings are present. One is ours, the other is logback-classic which is coming from the dropwizard-jackson dependency. The problem is when we try to exclude logback-classic from the dependencies we get

问题 I'm building an executable jar-with-dependencies using maven. My application uses log4j and there's an appropriate log4j.properties file under src/resources. My problem is that there are other log4j.properties files floating around so when maven builds the jar-with-dependencies, it's grabbing one of those instead of the one I want it to, and skipping any others it finds due to log4j.properties already being included. Anyone know of a way around this? 回答1: As per the documentation of jar-with

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
