java - Spring injection with @autowired doesn't work -
i'm building sample application jersey , spring.
all works good, can call controller found, when i'm trying access service, null. it's autowired spring, should not null.
this restcontroller
@path("/restexample") @component @scope("request") @produces({ mediatype.application_json }) @consumes({ mediatype.application_json }) public class restresources { @autowired protected restservices restservices; @get @path("/resource/{id}") public response getresourcewithid(@pathparam("id") integer resourceid) { return eomutils.buildsuccessresponse(restservices.getdata(resourceid)); } } this restservices class
@service public class restservicesimpl implements restservices { @autowired protected restdao restdao; @override public string getdata(integer resourceid) { return restdao.getdata(resourceid); } @override public string getdata() { return restdao.getdata(); } and application-context xml configuration file

i can enter in restresource classes, restservices class null.
where i'm wrong?
i haven't done spring in forever, believe issue not loading restresources class ioc container.
you need define restresources in application-context , load applicationcontext.
i see have context:component-scan com.ep.eom.poc.*. restresources under com.ep.eom.poc package?
if you're trying grab class "raw", won't have dependencies injected it.
