Question

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

在服务器启动时遇到以下异常，我猜它希望某处有一个默认构造函数。那么，spring-data-solr是否存在solr muticores实现的限制，这是我的实现，

存储库

    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);
        }
    }

的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>

例外

    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.

代码中的

有

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

但是您的MembershipDocumentRepository无法使用CustomMembershipDocumentRepository的自定义实现进行构建。

如果你实现了它，请检查name.it必须与MembershipDocumentRepository在同一个包中并命名为MembershipDocumentRepositoryImpl（这是它的默认命名。

采用Solr 4.1多核的Spring Data Solr

存储库

的applicationContext-solr.xml
