Improving log4j so it can easily be used with servlet logging -------------------------------------------------------------
Key: LOG4J2-42 URL: https://issues.apache.org/jira/browse/LOG4J2-42 Project: Log4j 2 Issue Type: Wish Components: API Reporter: Curt Arnold On May 30, 2010, at 11:49 AM, Thorbjørn Ravn Andersen wrote: There is one more thing that I would really like to see in log4j 2.0, namely the ability for a servlet to log to a servlet container using log4j (and in slf4j too but that is a different story). Currently that cannot be done, because there is no way for the code asking for the logger to pass a "this" reference to the logging framework. I would suggest that in log4j 2.0 the LoggerManager.getLogger() signature is changed to accept the class (as now), and a varargs of Objects. The objects are passed to the appender when needing to do the actual logging, allowing a ServletLoggerAppender to look for any object extending GenericServlet and invoke its log method. For client code it would mean that the logger object was retreived similar to: Logger log = Logger.getLogger(this.getClass(), this); We might even consider making the rule in log4j 2.0 that "the name of the logger is the full name of the class of the first object"[2]. In that case we could make do with: Logger log = Logger.getLogger(this); This would most likely also result in much other code being cleaner by allowing to drop the "getClass()" clause. What do you think?
