나는 많은 것을 시도했지만 내 저지 자원에서 나의 "searchservice"가 무작위로 인스턴스화 된 것으로 보인다. SearchResource의 SearchService는 거의 항상 null입니다.스프링 4 + 유니폼 통합 @Autowired
보시다시피 나는 스프링 저지 종속성을 추가했습니다.
@Component
public class SearchService {
private static final Logger LOGGER = Logger.getLogger(SearchService.class);
@Autowired
private IPublicationRepository repository;
@Autowired
private Neo4jTemplate template;
private static final Integer PAGE_SIZE = 20;
public SearchService() {
LOGGER.debug("search service initialzed " + this);
}
public Response searchQuery(String query) {
PageRequest request
= new PageRequest(1, PAGE_SIZE);
LOGGER.debug("repo : " + repository);
Page<Publication> res = repository.findPublicationByTitle(query, request);
//repository.query(query, null);
return Response.ok().entity(res.getContent()).build();
}
public IPublicationRepository getRepository() {
return repository;
}
public void setRepository(IPublicationRepository repository) {
this.repository = repository;
}
public Neo4jTemplate getTemplate() {
return template;
}
public void setTemplate(Neo4jTemplate template) {
this.template = template;
}
}
