HandlerResult now requires MethodParameter as input
HandlerAdapter's should always be able to provide a MethodParameter which in turn ensures that HandlerResultHandler's have full type information from method declarations. This commit also introduces ResolvableMethod for use in tests to make it easy to obtain MethodParameter return types. Issue: #128

|

* Convenience class for use in tests to resolve a {@link Method} and/or any of
|
||||
* its {@link MethodParameter}s based on some hints.
|
||||
*
|
||||
* <p>In tests we often create a class (e.g. TestController) with diverse method
|
||||
* signatures and annotations to test with. Use of descriptive method and argument
|
||||
* names combined with using reflection, it becomes challenging to read and write
|
||||
* tests and it becomes necessary to navigate to the actual method declaration
|
||||
* which is cumbersome and involves several steps.
|
||||
*
|
||||
* <p>The idea here is to provide enough hints to resolving a method uniquely
|
||||
* where the hints document exactly what is being tested and there is usually no
|
||||
* need to navigate to the actual method declaration. For example if testing
|
||||
* response handling, the return type may be used as a hint:
|
||||
*
|
||||
* <pre>
|
||||
* ResolvableMethod resolvableMethod = ResolvableMethod.on(TestController.class);
|
||||
|
||||
* ResolvableType type = ResolvableType.forClassWithGenerics(Mono.class, View.class);
|
||||
* Method method = resolvableMethod.returning(type).resolve();
|
||||
*
|
||||
* type = ResolvableType.forClassWithGenerics(Mono.class, String.class);
|
||||
* method = resolvableMethod.returning(type).resolve();
|
||||
*
|
||||
* // ...
|
||||
* </pre>
|
||||
*
|
||||
* <p>Additional {@code resolve} methods provide options to obtain one of the method
|
||||
* arguments or return type as a {@link MethodParameter}.
