Empty validatedBy in @Constraint

阅读更多关于 Empty validatedBy in @Constraint

问题 I noticed that all built-in constraints have an empty value for the validatedBy parameter in @Constraint . i.e. @Constraint(validatedBy = {}) First, why are they allowed to have an empty value for validatedBy ? I thought you can leave it blank only for constraint composition that does not need addtional validation? Also, note that the Hibernate Validator can still find a validator implementation class for each built-in constraint, despite the validatedBy is empty, but if I leave the

Is it possible to have both a validator for a form and annotation constraints? For example to have in a form object this field: @NotEmpty private String date; but then validate the date's pattern in a validator.

In the java world there is the bean validation framework JSR-303 which is a nicely well thought out strategy for performing data validation in both the presentation and persistence layers of an application.

Are there anything similar to JSR-303 in C#? There is the Enterprise Library Validation block. http://msdn.microsoft.com/en-us/library/ff648831.aspx It may not do some of the specific items you are asking about (i18n)
