for reason, spring isn't able auto wire repo service class. i've gone through every thread deals similar problems , couldn't solve problem,
here code.
public interface wprocessitemdetailsrepo extends pagingandsortingrepository<wprocessitemdetail, long>, jpaspecificationexecutor<wprocessitemdetail>{ } and service class
@service("processitemdetailsservice") @transactional public class wprocessitemdetailsservice implements serializable{ /** * */ private static final long serialversionuid = 2395733723021028217l; @autowired wprocessitemdetailsrepo detailsrepo; public wprocessitemdetail save(wprocessitemdetail detail){ return detailsrepo.save(detail); } public list<wprocessitemdetail> save(list<wprocessitemdetail> details){ return (list<wprocessitemdetail>) detailsrepo.save(details); } } when try run program, fails following stack trace

i think forgot annotation interface:
@repository public interface wprocessitemdetailsrepo extends pagingandsortingrepository<wprocessitemdetail, long>, jpaspecificationexecutor<wprocessitemdetail> {}
