I am assuming you are using Eclipse as your developing environment. Eclipse Juno, Indigo and Kepler when using the bundled maven version(m2e), are not suppressing the message SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder”. This behaviour is present from the m2e version 1.1.0.20120530-0009 and onwards. Although, this is indicated as an error your logs will be … Read more
I am assuming that you’re referring to SLF4J’s convention of expanding parameters, e.g.: float f; … logger.debug(“My number is {}”, f); So, the answer is no. As of SLF4J 1.7.7, what you’re asking to do is impossible as SLF4J’s expansion algorithm doesn’t allow for custom renderers (such as the one available via Log4J). Seems worthy … Read more
Add the following to your logback.xml configuration file: <logger name=”org.hibernate.engine.jdbc.spi.SqlExceptionHelper” level=”OFF”/> The instruction: level=”OFF” tells Logback to disable all log output for a given logger.
You have included a dependency on the SLF4J API, which is what you use in your application for logging, but you must also include an implementation that does the real logging work. For example to log through Log4J you would add this dependency: <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.5.2</version> </dependency> The recommended implementation would be logback-classic, which … Read more
You will not ever have more than one root-logger, so your question is a bit misleading. What you are looking for is how to fine-tune which events each of the appenders does log. And for that, you add a ThresholdFilter to each of the appenders: http://logback.qos.ch/manual/filters.html#thresholdFilter <filter class=”ch.qos.logback.classic.filter.ThresholdFilter”> <level>INFO</level> </filter> Configure level INFO for the … Read more
Heiko’s approach will probably work, but will lead to none of the dependencies of the 3rd party lib to be downloaded. If you only want to exclude a specific one use exclude. libraryDependencies += “foo” % “bar” % “0.7.0” exclude(“org.baz”, “bam”) or … excludeAll( ExclusionRule(organization = “org.baz”) ) // does not work with generated poms!
You do not need to give the JVM a different log implementation. The logging code searches for the log4j.properties file using the classpath. So all you need to do is ensure that your test log4j.properties file is in a location that it will find before the release file. I use Maven, which lays out files … Read more
Better to always download as your first try, the most recent version from the developer’s site I had the same error message you had, and by downloading the jar from the above (slf4j-1.7.2.tar.gz most recent version as of 2012OCT13), untarring, uncompressing, adding 2 jars to build path in eclipse (or adding to classpath in comand … Read more
If you want to use slf4j simple, you need these jar files on your classpath: slf4j-api-1.6.1.jar slf4j-simple-1.6.1.jar If you want to use slf4j and log4j, you need these jar files on your classpath: slf4j-api-1.6.1.jar slf4j-log4j12-1.6.1.jar log4j-1.2.16.jar No more, no less. Using slf4j simple, you’ll get basic logging to your console at INFO level or higher. … Read more
The better way. I think, is to use SLF4J API + some of its implementation. For Android applications you can use the following: Android Logger is the lightweight but easy-to-configure SLF4J implementation (< 50 Kb). LOGBack is the most powerful and optimized implementation but its size is about 1 Mb. Any other by your taste: … Read more
