i have spring mvc rest channel:

@controller @requestmapping("/rest") public class rest {

and have method:

@requestmapping(value = "/dosomething") public @responsebody dosomethingresultdto dosomething(     @requestbody dosomethingrequestdto)

now need name of user logged in. method

httpservletrequest.getuserprincipal()

but how here? have annotations headers (@requestheader), or cookies (@cookievalue). how can principal in method?

you can inject principal object controller handler method

@requestmapping(value = "/dosomething") public @responsebody dosomethingresultdto dosomething(     @requestbody dosomethingrequestdto, principal principal)
