The Clean Code book states:
"The ideal number of arguments for a function is zero (niladic)." (...) "Arguments are hard. They take a lot of conceptual power. That's why I got rid of almost all of them from the example. Consider, for instance, the StringBuffer in the example. We could have passed it around as an argument rather than making it an instance variable, but then our readers would have had to interpret it each time they saw it. When you are reading the story told by the module, includeSetupPage() is easier to understand then includeSetupPageInto(newPageContent). The argument is at a different level of abstraction than the function name and forces you to know a detail. In other others, StringBuffer that isn't particularly important at that point."
But using that specific clean-code technique is dangerous when using default SpringBoot settings.
Let's understand this issue well with an experiment.
