问题 I have spring boot application with Logback configured in logback.xml . This app is deployed as *.war to WildFly 8.2.1 (standalone mode) and has excluded WildFly's logging. During deployment WildFly logs all messages to console until logback for my application is configured. Last message is like "ch.qos.logback.classic.joran.JoranConfigurator@5ab89105 - Registering current configuration as safe fallback point" . After it, my app continues logging into file, but all messages from WildFly are

最强最全常用开发库 - 日志类库详解

Java日志库是最能体现Java库在进化中的渊源关系的,在理解时重点理解日志框架本身和日志门面,以及比较好的实践等。要关注其历史渊源和设计(比如桥接),而具体在使用时查询接口即可, 否则会陷入JUL(Java Util Log), JCL(Commons Logging), Log4j, SLF4J, Logback,Log4j2傻傻分不清楚的境地。@pdai 日志库简介 我认为全面理解日志库需要从下面三个角度去理解:@pdai 最重要的一点是 区分 日志系统 和 日志门面 ; 其次是日志库的使用, 包含配置与API使用;配置侧重于日志系统的配置,API使用侧重于日志门面; 最后是选型,改造和最佳实践等 日志库之日志系统 java.util.logging (JUL) JDK1.4 开始,通过 java.util.logging 提供日志功能。虽然是官方自带的log lib,JUL的使用确不广泛。主要原因: JUL从JDK1.4 才开始加入(2002年),当时各种第三方log lib已经被广泛使用了 JUL早期存在性能问题,到JDK1.5上才有了不错的进步,但现在和Logback/Log4j2相比还是有所不如 JUL的功能不如Logback/Log4j2等完善,比如Output Handler就没有Logback/Log4j2的丰富,有时候需要自己来继承定制

logbback generating too many logs on Tomcat console at startup

风流意气都作罢 提交于 2020-01-12 06:20:08
问题 When putting logback.xml in src/main/resources/ folder of my web-application, its working fine. However, when using LogbackConfigListener (as explained here) in web.xml to configure location of logback.xml file. The log file is generated successfully. But, additionally there are too many DEBUG logging messages appears on the console of tomcat server. It delays tomcat server start-up time. These DEBUG messages are part of 3rd party library files like Hibernate. logback.xml file: <configuration

Logback Do not inherit root appenders

老子叫甜甜 提交于 2020-01-11 09:39:06
问题 I have a logback config where I have one logger that should not inherit the syslog appender that has been added to the root logger. I can't find anywhere in the documentation how to do this. <root level="DEBUG"> <appender-ref ref="STDOUT" /> <appender-ref ref="FILE" /> <appender-ref ref="SYSLOG" /> </root> <logger name="jsonlogger" level="INFO"> <appender-ref ref="SYSLOGJSON" /> </logger> In this example, I do not want jsonlogger to inherit the syslog appender-ref from root. 回答1: Turn off

Java可以如何实现文件的监听

应用中使用logback作为日志输出组件的话,大部分会去配置 logback.xml 这个文件,而且生产环境下,直接去修改logback.xml文件中的日志级别,不用重启应用就可以生效 那么,这个功能是怎么实现的呢? 应用中使用logback作为日志输出组件的话,大部分会去配置 logback.xml 这个文件,而且生产环境下,直接去修改logback.xml文件中的日志级别,不用重启应用就可以生效 那么,这个功能是怎么实现的呢? I. 问题描述及分析 针对上面的这个问题,首先抛出一个实际的case,在我的个人网站 Z+中,所有的小工具都是通过配置文件来动态新增和隐藏的,因为只有一台服务器,所以配置文件就简化的直接放在了服务器的某个目录下 现在的问题时,我需要在这个文件的内容发生变动时,应用可以感知这种变动,并重新加载文件内容,更新应用内部缓存 一个最容易想到的方法,就是轮询,判断文件是否发生修改,如果修改了,则重新加载,并刷新内存,所以主要需要关心的问题如下: 如何轮询? 如何判断文件是否修改? 配置异常,会不会导致服务不可用?(即容错,这个与本次主题关联不大,但又比较重要...) II. 设计与实现 问题抽象出来之后,对应的解决方案就比较清晰了 如何轮询 ? --》 定时器 Timer, ScheduledExecutorService 都可以实现 如何判断文件修改? --
