What is global error (in spring validation)?

Question

I'm checking spring-validation Errors(BindingResult) interface. It mentions global errors in contrast with field erros. What are global errors?

Answer 1

FieldError (javadoc)

• registered via rejectValue (javadoc)

• attached to a field

  Example:

  errors.rejectValue("name", "name.empty", "cannot be empty")`
  

ObjectError (global error) (javadoc)

• registered via reject (javadoc)

• not attached to a specific field (either multifield or not field related)

  Examples:

  errors.reject("password.mismatch", "Password doesn't match confirm password")
  errors.reject("optimistic.out-out-date", "This page has been saved in the meantime. Reload it and start editing it again")
