+		<description>
+			Using a `@PostConstruct` method is usually only done when field injection is used and initialization needs to be performed after that.
+
+			It's better to do this directly in the constructor with constructor injection, so that all logic will be encapsulated there.
+			This also makes using the bean in environments where JavaEE is not present - for example in tests - a lot easier, as forgetting to call the `@PostConstruct` method is no longer possible.
