destroy method name
for a bean as opposed to
explicit specification of a method name. The value "(inferred)" is specifically
designed to include characters otherwise illegal in a method name, ensuring
no possibility of collisions with legitimately named methods having the same
name.
Currently, the method names detected during destroy method inference are "close" and "shutdown", if present on the specific bean class.

The default is singleton status, although this is only applied once
a bean definition becomes active in the containing factory. A bean
definition may eventually inherit its scope from a parent bean definition.
For this reason, the default scope name is an empty string (i.e., ""
),
with singleton status being assumed until a resolved scope is set.

This applies to constructor resolution, factory method resolution, and also init/destroy methods. Bean property accessors have to be public in any case and are not affected by this setting.
