Example validation annotations

[HarryEH]

#3053

Problem:

As described in the Issue #3053, the Saying validation annotation doesn't entirely make sense.

Solution:

I have removed the @Max annotation from the Saying class and removed the @Valid annotation from the resource. To still show the annotation in use I have modified the Person class in core and the people resource to reflect that. I have also added a test to show the validation in action on the resource.

Result:

I know adding age to a person isn't a particularly sensible thing to do normally, but it is a good way to show basic use of these annotations in action. Feedback on the test would also be appreciated, without an exception mapper I'm not sure what to test for - other than what I have implemented.

Seems good overall, some minor things:

• if you'd like to make the example a bit more sensible, perhaps you could use a year of birth field instead of age. @Max and @Min would work with that too.
• the documentation also needs to be updated, the line "Lastly, the bean leverages validation to ensure the content size is no greater than 3." should be removed from here.

Thanks!! I have made the changes suggested, and updated the documentation 😄. Also added a test for the @Max(value = 9999).
