Spring Data Solr with Solr 4.1 multicores

问题

    Trying to implement Spring-Data-Solr with Solr 4.1 multicores, 

At server startup getting following exception, I guess it expecting a default constructor somewhere. So, is there a limitation of spring-data-solr with solr muticores implementation, here is my implementation,

repositories

    public interface MembershipDocumentRepository extends
            CustomMembershipDocumentRepository,
            SolrCrudRepository<MembershipDocument, String> {
    }


 created 'repository' manually instead of autowiring/injection.......

    @Service
    public class RepositoryMembershipIndexService implements MembershipIndexService {   
        @Autowired
        private SolrTemplate solrMembershipTemplate;

        private MembershipDocumentRepository repository = new SolrRepositoryFactory(
                this.solrMembershipTemplate)
                .getRepository(MembershipDocumentRepository.class);

        @Transactional
        @Override
        public void addToIndex(Membership membershipEntry) {
            MembershipDocument document = MembershipDocument.getBuilder(
                    ...           
            repository.save(document);
        }
    }

applicationContext-solr.xml

        <solr:repositories
            base-package="net.pegonwheels.spring.datasolr.domain.repository.solr" />
        <beans profile="prod">
            <solr:solr-server id="solrMembershipServer" url="${solr.server.url.membership}" />
            <bean id="solrMembershipTemplate" class="org.springframework.data.solr.core.SolrTemplate">
                <constructor-arg ref="solrMembershipServer" />
            </bean>
        </beans>

exception

    At server startup getting following exception, I guess it expecting a default constructor somewhere. So, is there a limitation of spring-data-solr with solr muticores implementation. Can somebody please help me, thanks a ton in advance.

回答1:

in code u have

private MembershipDocumentRepository repository = new SolrRepositoryFactory(this.solrMembershipTemplate)
       .getRepository(MembershipDocumentRepository.class);

but your MembershipDocumentRepository can not be build with out custom implemention of CustomMembershipDocumentRepository.

if you implemented it check the name.it must be in the same package as MembershipDocumentRepository and named MembershipDocumentRepositoryImpl ( this is the default naming for it.
