log4j2

问题 So I'm trying to learn log4j2 and wrap my head around the loggers and their levels and parental propagation. Currently my source hierarchy runs is: ├── main │ ├── java │ │ └── calculatorMain │ │ ├── Main.java │ │ ├── someClass2.java │ │ └── someClass1.java │ └── resources │ ├── Excels │ │ └── TestExcel.xlsx │ ├── FXMLs │ │ └── mainWindow.fxml │ └── log4j2.xml and my calculatorMain is: Public class Main extends Application { private static final String mainWindow = //FXML stuff private static

问题 I have an WebSphere Application Server which runs an WebApp. I start the Server from Eclipse. The main logging framework in that application is log4j2, but there are some third party libraries which use java.util.logging. I want to redirect those logs to log4j2 so it uses my filters, log format etc. Therefore I tried to add the Log4j JDK Logging Adapter. I added the necessary JAR (I lacked only log4j-jul as I already had the other log4j-jars for other purposes) to the Build Path and to the

问题 I use log4j2 2.10.0 and have the following code: SingleChronicleQueue q = SingleChronicleQueueBuilder.binary(args[0]).blockSize(536870912).build(); ExcerptAppender a = q.acquireAppender(); char[] chars = "abcdefghijklmnopqrstuvwxyz".toCharArray(); StringBuilder sb = new StringBuilder(); Random random = new Random(); for (int i = 0; i < 1000; i++) { char c = chars[random.nextInt(chars.length)]; sb.append(c); } String t = sb.toString(); for (int i = 0; i < 1000000; i ++ ) { m_logger.info(i + "

问题 I am using the SystemPropertiesLookup lookup to configure my Log4J2 configuration. The system properties get set as the first line in my main method. The problem is that, when Log4J loads the configuration, the main method is not yet called, and so, the system properties are not yet filled in. Here is my log4j2.xml: <?xml version="1.0" encoding="UTF-8"?> <configuration status="WARN" packages="org.base"> <appenders> <Console name="Console" target="SYSTEM_OUT"> <PatternLayout pattern="

问题 Within my Servlet-based application, I would like to log events for startup and shutdown. I've tried to implement the ServletContextListener interface to do this: public class DiagnosticListener implements ServletContextListener { private static final Logger LOG = LogManager.getLogger(DiagnosticListener.class); @Override public void contextInitialized( final ServletContextEvent sce ) { LOG.info("Context initialized."); } @Override public void contextDestroyed( final ServletContextEvent sce )

问题 I am trying to implement log4j 2 but it keeps throwing the following error. > ERROR StatusLogger Log4j2 could not find a logging implementation. > Please add log4j-core to the classpath. Using SimpleLogger to log to > the console... > ERROR LogExample This Will Be Printed On Error > FATAL LogExample This Will Be Printed On Fatal I have tried the solution given on the net. But the don't seem to be working for me. This is the code that I am trying to run. package demo; import org.apache.logging

问题 I'm trying to use log4j2 on Android Project (I'm working on Android Studio). In order to simplify this question, I will explaine what I've done in a simple dummy project (I got the same error in the real project than in this dummy project). I create a simple dummy project with a main activity. I add the log4j2 libs... This is the gradle: apply plugin: 'com.android.application' android { packagingOptions { exclude 'META-INF/LICENSE' exclude 'META-INF/NOTICE' } compileSdkVersion 21

问题 ( F.Y.I. I already searched out many documents in Internet. I'm using storm-0.10.0-beta1. Configuration file of log4j2 in Storm is worker.xml ) Now, I try to use log4j2. I'm searching out way of deleting old logs but I cannot find out. Part of configuration is like below. <RollingFile name="SERVICE_APPENDER" fileName="${sys:storm.home}/logs/${sys:logfile.name}.service" filePattern="${sys:storm.home}/logs/${sys:logfile.name}.service.%d{yyyyMMdd}"> <PatternLayout> <pattern>${pattern}</pattern>

问题 I would like to change some properties from the log4j2.xml file depending on the my application.properties, so for example define some properties and then substitute in the log4j2 those properties that are parameters. I ran different approaches but I still not get the right thing. I would like to have different configs depending on the environment (DEV, QA or PROD). Can someone guide me how to accomplish this? So, I'm trying to have this in my properties #Place holders for log4j2.xml file log

问题 I am using log4j2 and slf4j in my project & using maven for the build. I am using the following pom file (releveant dependencies shown only) but I am getting the error copied below with this pom file - any idea what I need to add/remove to get this to work. I have already visited the url in the error as well as the log4j2 dependencies page so please do not just point to URLs in your response. Message: SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no
