Configuring async loggers in log4j2.properties

由 别说谁变了你拦得住时间么 提交于 2019-12-07 10:58:43
问题 I want to make some loggers asynchronous in log4j2.properties file. In the xml format you can add as <Loggers> <AsyncLogger name="com.foo.Bar" level="info"> </AsyncLogger> </Loggers> I tried it in log4j2.properties as loggers = com-foo-Bar asyncLogger.com-foo-Bar.name = com.foo.Bar asyncLogger.com-foo-Bar.level = INFO But this syntax seems to be wrong. What is the correct way to configure it? 回答1: Below is one way of using AsyncLogger in log4j2 properties file - logger.com.foo.Bar.type =

BasicConfigurator replacement in log4j2

由 佐手、 提交于 2019-12-07 09:43:51
问题 I am working on a log4j 1 to log4j 2 migration. Inside a AppConfigInitializer file we use something like this - BasicConfigurator.configure(consoleAppender); What shall I replace this with to get it working in log4j2. I am using the backward compatibility bridge as well but that has broken BasicConfigurator implementation. I think I need to do this using config file, but not able to find how. 回答1: The solution above works, but since default log level is ERROR, not all logs are shown. Log

How to include multiple log4j2.xml files in a project?

由 一笑奈何 提交于 2019-12-07 08:25:32
问题 My Project is composed of multiple modules. Each module can run on its own and have a separate log4j2.xml Say Project X is composed of three modules: Module A has log4j2.xml (contains Loggers and Appenders) Module B has log4j2.xml Module C has log4j2.xml While integrating the modules, I have to manually copy-paste the Loggers and Appenders from each module's log4j2.xml into the project specific log4j2.xml file. To avoid copy-paste, I've looked for XInclude to include multiple files but it

Getting properties programmatically from Log4j2 XML config

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-07 05:07:51
问题 In my Log4j2 config file, I have this: <?xml version="1.0" encoding="UTF-8"?> <Configuration status="WARN" strict="true" name="XMLConfig" packages="org.apache.logging.log4j.test"> <Properties> <Property name="baseDir">log-dir/</Property> <Property name="defaultLogfileName">default-log-file</Property> </Properties> Now, in some of my code, I create custom loggers. I need to access the value of "baseDir" and change it. I've tried using getProperties from the context like this: LoggerContext

springboot整合日志(二)----------logback( log4j2调整为logback )

由 早过忘川 提交于 2019-12-07 04:51:15
springboot的日志框架别的博客上说的也比较多，很多都可用。但是我这里是有一些特殊的项目经历，值得一说。 原本项目中使用的log4j2，也就是上一篇 springboot整合日志(一)----------log4j2 中讲的。结果由于要部署到京东云上，他们的日志收集系统要求用logback的控制台输出日志。通过控制台就能收集到日志，并声称日志文件。所以我们的项目就要改造成logback的日志系统。 然后发现稍微调整log4j2的日志配置就能实现logback控制台输出。调整如下： 1.pom.xml中的日志依赖改为logback。 2. 删除掉resource文件下的log4j2的日志配置。 3.在yml文件中删除掉对应日志文件的引入即可。即下面这行去掉 logging: config: classpath:log4j2.xml 4.在类上加上lomback的注解不变。即可在方法上引入日志。 5.启动项目，即可发现日志已经生效。打印出彩色日志在控制台。满足了要求。 但是，等部署到测试环境，要去看日志文件时，发现，这个日志配置虽然满足了生产环境的要求，却不满足测试环境输出日志文件的需求。还是要加上配置文件，给出控制台打印或者日志打印的日志输出模式。实际经过上面的修改后。logback的日志框架引入什么都没有了只剩下一个@Slf4j这样一个类上面的注解。只要注解在，加上log

Bridging from log4j2 to slf4j

由 左心房为你撑大大i 提交于 2019-12-07 04:35:51
问题 I'm using Slf4j 1.7.x in conjunction with Logback in my applications (it is a Dropwizard-application). Now we have libraries that use the log4j2 (not log4j), and the logging goes to /dev/null . I can't find a logj2-over-slf4j or log4j2-to-slf4j library in any exising maven application, what is the trick? 回答1: You may use the Log4j 2 to SLF4J Adapter to route your Log4j2 logs to your slf4j implementation. You are right that slf4j itself does not provide an adapter for log4j2. 来源： https:/

log4j2: registering custom TriggeringPolicy

由 随声附和 提交于 2019-12-06 12:35:50
问题 I have written a custom TriggeringPolicy for log4j2 that is suppose to roll-over .log file at the end of every hour/day/your_interval following advices from this SO post. Though I followed TimeBasedTriggeringPolicy conventions (naming, etc) I am not able to see my policy being instantiated and used. Solution comprise of 3 java files + a maven file and is available at the github. Here you can find main lines from the policy itself: @Plugin(name = "FTimeBasedTriggeringPolicy", category = "Core"
