java - Spring MVC and JSR 303 - Manual Validation -

-

i'm using spring mvc 3 , jsr 303. have form backing object has beans of different types in it. depending on request parameter value, i'll have choose bean validate , save. can't use @valid validation since bean validate not known until runtime.

i able inject javax.validation.validator controller, i'm not sure how validate bean , store errors in bindingresult/error in "spring way".

i need in handler method, rather initbinder method, because of request mapping.

[edit]

the problem i'm having validate(object, errors) doesn't recognize nested beans. bean validate accessed through foo.getbar().getbean(), foo form backing object. when validate(foo.getbar().getbean(), errors), following error message.

jsr-303 validated property 'property-name' not have corresponding accessor spring data binding

has done before? thanks.

just guess, have tried

 errors.pushnestedpath("bar.bean"); // path nested bean  validate(foo.getbar().getbean(), errors)  errors.popnestedpath();

that's how bindingresult used validation of nested beans.
