SLF4J allows the end-user to plug in the desired logging framework at deployment time. At this time if you are only interested in obtaining the coordinates for using SLF4J API with a logging backend, you can jump to the relevant section. As customary in programming tradition, here is an example illustrating the simplest way to output "Hello world" using SLF4J. It begins by getting a logger with the name "HelloWorld". This logger is in turn used to log the message "Hello World". To run this example, you first need to obtain slf4j artifacts. Once that is done, add the file slf4j-api Compiling and running HelloWorld will result in the following output being printed on the console. This warning is printed because no slf4j provider or binding could be found on your class path. The warning will disappear as soon as you add a provider to your class path.

From the client's perspective the slf4j-api, more specifically classes in the org. Like 3.

The reason that it has been written as an alternative to Commons Logging, is that Commons Logging loads your logging library by using some whizzy Java ClassLoader techniques.

However, it is often a good idea to declare an explicit dependency to slf4j-api in order to fix the correct version of slf4j-api your project by virtue of of Maven's "nearest definition" dependency mediation rule. It offers a generic API, making the logging independent of the actual implementation. If SLF4J cannot find a provider on the class path it will emit a single warning message and default to no-operation implementation. This bypasses the service loader mechanism for finding providers and may shorten SLF4J initialization. Reload4j is a drop-in replacement for log4j version 1. About Baeldung About Baeldung. Only messages of level INFO and higher are printed. An example project configured this way is available here. Here are few usage examples: The statement logger.

There are many implementations to choose from, including Logback and Log4j2.

It follows that SLF4J version 1. Take a look at the official documentation to learn more about bridging existing frameworks. The lastest version available from Maven Central is 1. For example, if you are using slf4j-api Providers for popular logging frameworks SLF4J supports popular logging frameworks, namely reload4j, log4j 1. Critically, it has very minimal impact on your server's performance, with most of the profiling work done separately - so it needs no server changes, agents or separate services. It is now possible to pass multiple Markers , pass arguments with a Supplier or pass multiple key-value pairs. Get non-trivial analysis and trivial, too! The sample code below illustrates the typical usage pattern for SLF4J. Under the hood the Java compiler transforms the varargs part in methods into Object[].
