* Make java spring controller constructor public.
This lets users manually create the controller and inject the delegate in the
spring configuration file, instead of letting spring scan for controllers and
autowire the delegate.
* Ran spring-all-pestore.sh.
* Update spring samples with current code.
This is done so I can see my own changes better.
* Regenerate samples after 2.2.2.
* use baseName instead of paramName for spring annotations.
* update spring petstore samples to show the effects.
* Issue #4606 (Spring) SubClass annotations are missing from the base class
