public class Logger extends Object
Example, logging with the default application logger:
Logger.info("Hello!");
Example, logging with a custom logger:
Logger.of("my.logger").info("Hello!")
Each of the logging methods is overloaded to be able to take an array of arguments. These are
formatted into the message String, replacing occurrences of '{}'. For example:
Logger.info("A {} request was received at {}", request.method(), request.uri());
This might print out:
A POST request was received at /api/itemsThis saves on the cost of String construction when logging is turned off.
This API is intended as a simple logging API to meet 99% percent of the most common logging needs with minimal code overhead. For more complex needs, the underlying() methods may be used to get the underlying SLF4J logger, or SLF4J may be used directly.
