JarCastingSemantic Logger
Java: 
This little library is inspired by the talk Observability in einer Microservice Welt held on Berlin Expert Days 2018 by Andreas Weigel and Jakob Fels.
If you prefer to have some semantic to your logging and improve code readability you can use the SemanticLogger and its SemanticLoggerFactory which adds a thin layer around Slf4j.
The SemanticLoggerFactory can be used like the Slf4j LoggerFactory to create a new Logger by class, name or a delegateLogger:
SemanticLogger logger = SemanticLogger. getLogger(SomeClass.class);
SemanticLogger logger = SemanticLogger. getLogger("SomeLoggerName");
Logger delegateLogger = org.slf4j.LoggerFactory.getLogger(SomeClass.class);
SemanticLogger logger = SemanticLogger. getLogger(delegateLogger);
The SemanticLogger itself provides the following methods for logging:
SemanticLogger log = SemanticLoggerFactory.getLogger(MyClass.class); log.forTestPurpose(...); // will log a debug event log.asExpectedByDefault(...); // will log an info event log.toInvestigateTomorrow(...); // will log a warn event log.wakeMeUpInTheMiddleOfTheNight(...); // will log an error event
