As the previous examples have shown as well as those to follow, Log4j allows you to easily redefine logging behavior without needing to modify your application. It is possible to disable logging for certain part
You can see in above code examples that every time we define a LoggerConfig, we also provide logging level. By default log4j2 logging is additive. It means that all the parent loggers will also be used when a specific logger is used. Below image clarifies this situation. And herein poin...
Inserting log requests into the application code requires a fair amount of planning and effort. Observation shows that approximately 4 percent of code is dedicated to logging. Consequently, even moderately sized applications will have thousands of logging statements embedded within their code. Given thei...
