Added an integration-test that tests the exception-handling
* The integration-test uses WebTestClient to test the exception-handling
* Since this is a real integration-test, the exception-handling behave
exactly the same way
* The test-setup with the WebTestClient needs an additional dependency, to
work correctly - without it, the WebTestClient-Bean would not be intanciated
* The added test ExceptionHandlingApplicationIT tests exaclty the same stuff,
as ExceptionHandlingApplicationTest - this is no good test-design, but it
serves the intention, to compare the two approaches
* Since Spring-Boot configures the surefire-maven-plugin to ignore all tests,
that end with IT, the failsafe-maven-plugin has to be added to automatically
fire the new test - remember: you have to call "mvn verify" to fire IT

TODO... Passt der neue Test noch?
Added a working component-test for exceptions, thrown outside of controllers

TODO: An neuen Fehler anpassen, Separates Fehler-Template weg? Mehr...?
Added a working @ExceptionHandler
* Both handlers resolve the handled exception as 503 Internal Server Error
and are using the template "error/503", which was extended to print a
message, that the reported exception was catched and handled.
* If one starts the app, it is clearly visible, that the mechanism only
works for exceptions, that are thrown in the context of the controller.
* Also added a test-case, that shows, that MockMvc shows the expected
behaviour for exceptions, that are thrown inside the container.

WIP:Further refined the example...
* The view renders the question, if no answer is specified (initial request!)
* If a valid request is specified, the answer and the outcome is rendered
* If an invalid request (negative number!) is specified, the view generates
an exception, because it tries to resolve the Optional anyway

Added spring-boot-devtools
Kai Moritz [Sun, 27 Sep 2020 09:23:03 +0000 (11:23 +0200)]
Further refined the example
* Introduced an ExampleService
* The service checks the answer for
The Ultimate Question Of Life, The Universe And Everything
* Requests without any answer are tolarated, so that the page with the
question can be rendered
* Only numbers (Integer) are allowed as answer.
* Negative numbers are not allowed as answers: the service answers with an
empty Optional.
* The view contains a bug, that results in a 503 for negative answers.

Refined the example, to clearify the intent
* Removed unnecessary Annotation from test
* Renamed and pimped up the example templates
* Splitted up the test in separate units
* Remapped the controller to the root of the web-context
* Switched to @WebMvcTest, to load only the controller-layer

Renamed and repackaged the example for the blog-article

Initial Commit: Spring-Boot-Project, that pinns down a bug in a test-case
* I stumbled accros the unexpected behaviour of Springs MockMvc in a
test-case for one of my projects.
* This version pinned down the unexpected behaviour explicitly.
