I would say that you probably should write the validator to be thread-safe (just to be sure). But, that being said, from a quick look at the validation framework (check classes like DefaultValidationFactory, ValidationInterceptor, etc. inside of xwork), it looks like xwork caches the "validator config" and asks the validator factory for instances when they are needed. The validator factory retrieves the instance from the Object Factory, which is creating and injecting a new instance for each validation.
I say that you should still make them thread-safe because I would imagine at some point, the framework might create instances and cache / reuse them since reflections-based instantiation can be slow. -Wes On Sat, Jul 17, 2010 at 6:25 PM, Marshall Gunter <marsh...@mate1inc.com> wrote: > Writing my own. > > On 10-07-15 08:33 PM, Christopher Schultz wrote: >> >> -----BEGIN PGP SIGNED MESSAGE----- >> Hash: SHA1 >> >> Marshall, >> >> On 7/15/2010 9:27 AM, Marshall Gunter wrote: >> >>> >>> Do Struts 2 field validators need to be thread safe? >>> >> >> That depends on what you want to do with them.
