Using Logback but Log4j started displaying WARN no Appenders

混江龙づ霸主 提交于 2019-12-22 03:22:47
问题 I am using logback for my logging and it has been working however; the other day I started getting a warning log4j:WARN No appenders could be found for logger (org.apache.axis.i18n.ProjectResourceBundle). log4j:WARN Please initialize the log4j system properly. I am not using log4j nor have I ever with this project. I have a logback.xml in my resources folder. Any ideas on why this warning started to show up? 回答1: You must be using a library that does use log4j. Can you post anything more

问题 We've hit an issue when upgrading from spring-boot 1.3.2 to the recently released 1.3.3. Our application has been making use of the following dependencies, each the latest, without issue: <neo4j.version>2.3.2</neo4j.version> <sdn.version>4.0.0.RELEASE</sdn.version> <sdn.rest.version>3.4.0.RELEASE</sdn.rest.version> <neo4j.ogm.version>1.1.5</neo4j.ogm.version> Today I upgraded our spring-boot and Spring Data Neo4j -based application, which starts and works well with spring-boot 1.3.2.RELEASE,

tail logback log files with log level coloring in linux server

问题 We are migrating from log4j to logback, and with log4j we are using multitail with colorscheme to tail our log files with log level coloring. Can multitail do the same for logback ? is there any other simple solution for logback file tailing with color ? 回答1: I don't know what file formats are supported by multitail per default but you can easily create a new color scheme for logback (see multitail.conf). I added the current log4j colorscheme as an example: colorscheme:log4j cs_re:magenta::

SpringBoot整合日志框架LogBack

日志可以记录我们应用程序的运行情况,我们可以通过日志信息去获取应用程序更多的信息。常用处理java日志的组件有:slf4j、log4j、logback、common-logging等。其中log4j是使用得最多的日志组件。 而LogBack是基于Log4j基础上大量改良的一种日志框架,但是它不能单独使用,推荐配合日志框架SLF4J来使用。 LogBack当前分成三个模块:logback-core、logback-classic和logback-access;其中logback-core是其它两个模块的基础,就像spring框架里的spring-core一样。 Logback的核心对象 Logger:日志记录器 Appender:指定日志输出的目的地,目的地可以是控制台,文件 Layout:日志布局,指定日志信息的输出的格式 日志级别 DEBUG INFO WARN ERROR DEBUG < INFO < WARN < ERROR 我们一般不会去选择DEBUG级别,因为DEBUG级别会输出很多信息,包括一些无用的信息。 Log4j转换到LogBack 因为目前使用得最广泛的还是Log4j,要想转换到LogBack,可以使用这个 转换工具 。 比方说我们现在有一个log4j.properties文件。 ### 设置日志记录器### log4j.rootLogger = debug

1.简介   LogBack是一个日志框架,它与Log4j可以说是同出一源,都出自Ceki Gülcü之手。(log4j的原型是早前由Ceki Gülcü贡献给Apache基金会的) 1.1 LogBack,Slf4j,Log4j之间的关系   Slf4j是The Simple Logging Facade for Java的简称,是一个简单日志门面抽象框架,它本身只提供了日志Facade API和一个简单的日志类实现,一般常配合Log4j,LogBack,java.util.logging使用。Slf4j作为应用层的Log接入时,程序可以根据实际应用场景动态调整底层的日志实现框架(Log4j/LogBack/JdkLog...);   LogBack和Log4j都是开源日记工具库,LogBack是Log4j的改良版本,比Log4j拥有更多的特性,同时也带来很大性能提升。详细数据可参照下面地址: Reasons to prefer logback over log4j   LogBack官方建议配合Slf4j使用,这样可以灵活地替换底层日志框架。   (note: 为了优化log4j,以及更大性能的提升,Apache基金会已经着手开发了log4j 2.0, 其中也借鉴和吸收了logback的一些先进特性,目前log4j2还处于beta阶段) 1.2 LogBack的结构

Is it possible to find logback log files programmatically?

问题 It would be useful to automatically attach log files to support emails. I could set the path programmatically (as in Setting Logback Appender path programmatically), but I'd prefer to let users configure logging in the familiar way via logback.xml . So, can I find the files logback uses for logging? 回答1: You can get the list of all appenders in a certain context. To do this: LoggerContext context = (LoggerContext)LoggerFactory.getILoggerFactory(); for (Logger logger : context.getLoggerList())

How to get back MDC “inheritance” with modern logback?

问题 After going back to an older project and getting around to update its dependencies I had to realize that logback does not anymore propagate MDCs to children since version 1.1.5 : https://github.com/qos-ch/logback/commit/aa7d584ecdb1638bfc4c7223f4a5ff92d5ee6273 This change makes most of the logs nigh useless. While I can understand the arguments given in the linked issues, I can not understand why this change could not have been made in a more backwards compatible manner (as is generally usual

Creating logback logger programmatically

问题 I have a problem regarding to logback project. My requirement is I have to create log properties dynamically. Let me explain this by an example. My project creates socket communication with external system and it may have multiple sockets. For each socket, I want to have different log files which will contain the messages that is read and sent. To accomplish this, I create the logger for sockets programmatically. Problem is when I want to reconfigure loggers based on logback.xml (by adding
