log4j

问题 I don't know how to add dependency. My module needs Log4j. I added requirement to module info. I added also to gradle dependencies. I can run project, but I can't create custom runtime image. plugins { id 'java' id 'application' id 'org.openjfx.javafxplugin' version '0.0.5' } group 'eu.sample' version '2.0' repositories { mavenCentral() } javafx { modules = [ 'javafx.controls', 'javafx.fxml' ] } mainClassName = "$moduleName/eu.sample.app.Main" def lin_java_home = hasProperty('org.gradle.java

问题 I am using log4j for loggin purpose in my application. Since now to configure the logging i was using the following code : LogManager.resetConfiguration(); InputStream stream = Thread.currentThread().getContextClassLoader().getResourceAsStream("log4j.properties"); Properties props= new Properties(); props.load(stream); PropertyConfigurator.configure(props); But the problem with this was , that whenever i wanted to change the logging level during the process, i had to restart the server. So i

问题 for example I want to replace before compilation: #debug("${enclosing_method} this is debug message for " + userName) with: if (log.isDebugEnabled()) { log.debug("<real method name> this is debug message for " + userName); } 回答1: Don't. Use slf4j instead which allows you to avoid the check with {}. 回答2: Consider using log4j if your example reflects your primary aim. Quote needed: Preprocessor usage is bad OO practice could be of interest as well. 来源： https://stackoverflow.com/questions

问题 I want to migrate from Log4j 1.x to Log4j 2.x. So I'm trying to use log4j-1.2-api.jar as mentioned here. My application has an implementation of org.apache.log4j.spi.LoggingEvent , but I cannot find a way to use LoggingEvent with the log4j 2.x api bridge. Is there anyway that I can use LoggingEvent with log4j 2.2 ? Thanks. 回答1: Internally, log4j uses a LogEvent to carry all the data pieces (the log message, thread name, timestamp, markers, logger name, etc) to the appenders where they may

问题 I have multiple properties files in my Spring project. The spring context loads these properties and handles property overriding in a convenient manner. Is there a way to take the properties that are available to my Spring configuration XML files (ie. ${myprop} ) and use them in a similar fashion in my log4j.xml file? I know that I can pass system properties to log4j using -Dprop=value on startup, but I would prefer having all of the configuration in the properties files in my project. Is

问题 Is there a standard way to share a logging config (for log4j or logback for example) across all sub projects in a gradle project layout? What I do right now is put a copy of logback.xml (or log4j.properties ) in src/main/resources in each sub-project but this results in a lot of unnecessary duplication of this config file 回答1: This can be easily overcome using multiple working sets in gradle. Add a new folder in the root of the project, example "shared-resources" put our configs inside it,

问题 log4j.rootCategory feild in log4j.properties can have 4 different values namely: DEBUG,WARN,INFO and ERROR . Can you tell me which is most suitable for what cases? 回答1: From the least severe to the most one: ALL < DEBUG < INFO < WARN < ERROR < FATAL < OFF If you choose one of them log4j will print all messages of that type and of more severe type. Purposes: ALL : prints all messages* DEBUG : debug messages INFO : information that aren't problems WARN : not error but something that could cause

问题 I am planing to move web application to cloudfoundry along with mysql service. But I am getting below error. Its working fine with local environment. log file get generated also.

问题 I have a log4j logger that currently writes the log both to console and to a file, which works fine. Later I'd like to configure it to log INFO + ERROR to the logfile, but only show ERROR on console. What would I have to change to achieve this? log4j.rootLogger=INFO, console, MyFileAppender log4j.logger.org.apache.cxf=INFO, console log4j.logger.org.apache.cxf.interceptor.LoggingInInterceptor=INFO, console log4j.logger.org.apache.cxf.interceptor.LoggingOutInterceptor=INFO, console log4j

问题 I'm having trouble with an application that crashes when I deploy it to other computers who are running JRE 1.7. When I run this inside of NetBeans (or even directly from the JAR file) on my PC, everything is fine. But on another computer it fails at specific events (button clicks) during execution. So, I learned about logging using the log4j library. This gave me some information on a problem in my application, and the logging works perfectly, again on MY computer. But when I deploy the JAR
