Java Spring Annotations and Validation: A question.

[null]

Does anyone here know Spring?

I am seeing a difference between how automated validation (@Valid DTO name, BindingRequest) and manual validation work.

Manual validation by injected validator catches errors (against annotated constraints in DTO class) that automated validated misses.

So bindingResult has no errors when automated but Set<ConstraintViolation<>> is non empty when called on the same object using injected validator.validate(name)

Is this normal?

A: no it is not normal.

<mvc:annotation-driven/> has to go in the application context for automated checking to work properly
