java - Spring MVC requests processing order -

i have web service receives data clients , saves them map

@controller public class examplecontroller {     private final map<string, string> state = new concurrenthashmap<>();      @requestmapping(value = "/set-state", method = requestmethod.post)     public synchronized @responsebody void setstate(@requestparam string id,             @requestbody string updateddata) {         state.put(id, updateddata);     } } 

suppose client sends 2 requests 1 after another. both requests have same id, second request has updated data.

the question is, spring mvc guarantee setstate called request 1 data first? making method synchronized enough make sure i'll updated data request 2 in state map?
