问题 My project is using log4j 1.2.17. I have successfully injected my custom "Evaluator" into the SMTPAppender, using setEvaluatorClass : <appender name="email" class="org.apache.log4j.net.SMTPAppender"> <param name="EvaluatorClass" value="path.to.my.Evaluator" /> However, I would like to pass some params to my Evaluator, to make it configurable. I would like to use SMTPAppender.setEvaluator, but I cannot figure out how to set that up in log4j.xml. Another option would be the other SMTPAppender

问题 Can't get any flavour of Neo4j (1.7.2, 1.8.2, 1.9.RC2) running on my MacBook due to issues with not finding "file:conf/log4j.properties" and it looks like even with jakarta-log4j installed from ports am bumping up against not being able to play… is it missing a .jar in the install? Any ideas? I can find other log4j.properties relating to other apps. Already checked questions: Starting neo4j on mac , log4j can't initialize with my log4j.properties Neo4j RC 1.9.2 version(Java 1.7 is actually

问题 Is there a way to force a Log4j Logger to be released/garbage collected? In general, does Log4j "hang on" to Logger references in some static collection? I see the Logger.shutdown() method, which is deprecated and refers to LoggerManager.shutdown() , which doesn't sound like it addresses a single Logger instance. 回答1: You could take a look at the log4j source code yourself. Based on a quick trawl, I think the answers are: Is there a way to force a Log4j Logger to be released/garbage collected

问题 My software uses a Service Oriented Architecture (SOA). All the services (lets call them modules for simplicity) writes to a single log file. I would like to distinguish logging between modules. Below is how I would like my log message to look like. [MODULE-1] INFO - This is a test log message from MODULE ONE [MODULE-2] INFO - This is a test log message from MODULE TWO The advantage I see doing this is I would be able to grep necessary information while 'tail-ing' the logs. Also, while

问题 Are log files not meant to be read by machines but by users only? I wonder if there are file appenders for any logging framework that write their output to XML. 回答1: "Logging to XML" is quite a general requirement, because there is no such thing as the standard log file format. But since XML files are text files, which logging frameworks can write, and since many of those frameworks allow configuring log line format, I see no problem in defining your log output with XML tags of choice.
