web services - Set Jackson DeserializationContext Attribute in per-request, thread-safe manner -
i'm looking able add request-scoped attribute (a jax-rs containerrequestcontext because rather use jackson convert parameters objects jax-rs's ill conceived , clunky parameterconverterproviders ) deserializationcontext can obtained within jsondeserializer . must call convertvalue() rather readvalue() (not dealing actual json) not able create objectreader in each thread unless willing serialize map json string first , read -which incredibly inefficient. i'd able accomplishes following in per request manner: objectmapper om = new objectmapper(); //in request-scoped context: om.getdeserializationcontext().setattribute("requestcontext",containerrequestcontext) map<string,object> mapofrequestparameters = ... beanofvastimportance bean = om.convertvalue(mapofrequestparameters,beanofvastimportance.class) how can achieve without massive, superfluous overhead of needing create new objectmapper each individual request thread? this can achieve...
