Overriding logback configurations

由 旧时模样 提交于 2019-12-20 10:26:34
问题 Is there any way that we can override the logback configurations? I know that we define the logback configurations in file named logback.xml (usually stored in the path src/resources) and i know that by using <include> tag we can set an external file to be added to logback.xml just like below: <configuration> <!--<include url="file:///d:/ServerConfig.xml"/>--> <include file="${outPut}/ServerConfig.xml"/> <logger name="Server" LEVEL="DEBUG"> <appender-ref ref="FILEOUT" /> </logger> <root level

问题 How to globally enable debug for all the slf4j.Logger objects? 回答1: Programmatically, with logback: setLoggingLevel(ch.qos.logback.classic.Level.DEBUG); where public static void setLoggingLevel(ch.qos.logback.classic.Level level) { ch.qos.logback.classic.Logger root = (ch.qos.logback.classic.Logger) org.slf4j.LoggerFactory.getLogger(ch.qos.logback.classic.Logger.ROOT_LOGGER_NAME); root.setLevel(level); } 回答2: exists various capability to switch debug log on: this article have good explanation

Difference between Simple Logging Facade for Java and Apache Commons Logging

由 牧云@^-^@ 提交于 2019-12-20 08:57:14
问题 What is the difference between Simple Logging Facade for Java and Apache Commons Logging? 回答1: From the SLF4J FAQ: SLF4J is conceptually very similar to JCL. As such, it can be thought of as yet another logging facade. However, SLF4J is much simpler in design and arguably more robust. In a nutshell, SLF4J avoid the class loader issues that plague JCL. Do a google for "JCL classloader issues" for more on this... 回答2: While SLF4J can be used as a facade over libraries like Log4j, or JUL, it can

How can I get complete stacktraces for exceptions thrown in tests when using sbt and testng?

由 佐手、 提交于 2019-12-20 08:35:04
问题 The stacktraces are truncated - e.g. they end with [info] ... Using last or changing traceLevel doesn't help - it simply prints the complete stacktrace of the sbt wrapper. This is testing with testng (also I believe using scalatest and sl4j) 回答1: Using hints found in the documentation here: (quoted) You can configure the output shown when running with sbt in four ways: 1) turn off color, 2) show short stack traces, 3) full stack traces, and 4) show durations for everything. To do so you must

jul-to-slf4j for specific classes only

由 a 夏天 提交于 2019-12-20 05:33:25
问题 I'm working on a JSF-Project with Primefaces on Websphere Application Server. Since Primefaces uses java.util.logging, I'm using the jul-to-slf4j Bridge to capture the Primefacs Logs into my Log4J Logfile. But using the jul-to-slf4j Bridge, all java.util.logging Messages will be in my Logfile, including general Websphere Messages like "Application started" or "Server started". Can the jul-to-slf4j be configured, so it only redirects specific Messages (e.g. everything from org.primefaces ) to

问题 Good day, After " play new todo " (new scala project) -> " cd todo " -> " play dependencies " I get this one unresolved dependency " org.slf4j:slf4j-api:1.6.1 required by "net.sf.ehcache:ehcache-core:2.5.0, org.hibernate:hibernate-validator:4.2.0.Final, play:play_2.9.1:2.0" reason " Evicted by 1.6.4 ".

How to read log4j output to a web page?

由 人盡茶涼 提交于 2019-12-18 13:34:47
问题 I have a web page, used for admin purposes, which runs a task (image fetching from a remote site). In order to be able to debug the task using the browser only, no ssh etc, I'd like to be able to read all log output from the executing thread and spit it out to the web page. The task boils down to: Changing log level for current thread at the beginning of the call and restore when the call is done. Reading all log output by current thread and storing it in a string. So in pseudocode my execute
