问题 I am in need of adding programmatically a file logging, with file name generated dynamically. My code is like this: private static final Logger LOGGER = LogManager.getLogger(Archiver.class); public static void openLogfile(String folder) { String dateTime = "TODO"; String fileName = folder + "upload" + dateTime + ".log"; LOGGER.info("Opening " + fileName + " for logging."); // setting up a FileAppender dynamically... final LoggerContext ctx = (LoggerContext) LogManager.getContext(false); final

问题 We would like to use Log4j2 as the log binding with grails 3. From what I can figure out so far. We have many subordinate dependencies that use a variety of loggers, so we need to use the SLF4J API. Then, instead of letting grails / groovy / spring re-direct the SLF4J API to the Logback binding, we need to re-direct each to the Log4j2 binding. Since grails 3 uses the Logback binding, I am planning to go through each dependency in the build.gradle, exclude the Logback binding, and include the

问题 I would like to be able to detect when the app is missing a LOG4J2.XML configuration file, and in that case set some other defaults than what LOG4J2 has otherwise. Basically, I would like to run this code if a config file isnt found: // A default configuration that shows ALL Logger output, without a XML config! LoggerContext ctx = (LoggerContext) LogManager.getContext(false); Configuration config = ctx.getConfiguration(); LoggerConfig loggerConfig = config.getLoggerConfig(LogManager.ROOT

问题 I had a Java 8 project and my configuration file was in resource folder and everything worked fine. Now I switched to Java 9, added requirement for log4j.api , and configuration file cannot be found anymore. Do I need to add something else in my module-info file for the logger to find it's config? For now, it's like this module project.main { requires jdk.incubator.httpclient; requires jackson.databind; requires jackson.core; requires jackson.annotations; requires log4j.api; } The Project

问题 I'm trying to use Log4j2 to print the spring logs into a file and console. I guess it is a problem in my Log4j2 configuration. I have not been able to get it working. I have this configuration in my log4j2.xml file: <?xml version="1.0" encoding="UTF-8"?> <configuration name="defaultConfiguration" status="warn" strict="true" monitorInterval="5"> <properties> <property name="patternlayout">%d{ISO8601} [%t] %-5level %logger{36} - %msg%n%throwable{full}</property> <property name="filename">${env

问题 I am using log4j2 to log messages in console and in a file. I am getting a lot of Warn message which I do not want. I only want to see Debug and other messages. is it possible to suppress Warn messages while allowing Debug, Error and any other types of messages? I have looked at other answers here on stack overflow but they only tell about the suppression that suppresses all of the messages below that specific message level. For example, if I change my log level to Error I will automatically

问题 I am very confused with setting up logging with Apache Spark. Apache spark used Log4j for logging and it generates huge amount of log data. Is there a way to setup log4j for spark logs and use logback for application log. I am quite conversant with logback but it seems spark only support log4j. Below piece of code was working fine till i introduced apache spark. Any help in this regard will be helpful. import com.typesafe.scalalogging.LazyLogging import scala.util.{Failure, Success} import
