CAP in Motion 4.4 Input validation

Input validation | CAP in Motion 4.4 An order without a number. A quantity of zero. A product that doesn't exist. Each one will cause trouble later, far from where it came in. CAP checks input declaratively: annotations on the model, applied to every service and every client. Part 4 · Providing services · Episode 4.4 What you'll learn • @mandatory, @assert.range, @assert.format and @assert.target validate input declaratively. • Failures return 400, with a message and a target for each field. • Several failures come back together. • Custom messages use i18n keys, so they're translated with the request's language.
