【英文标题】：Error while initialising SolrRepository: Unsatisfied dependency expressed through field

【问题描述】：

这是给我以下异常的代码：

@SpringBootApplication
@ComponentScan(basePackages =  "com.ns.services.search", "com.ns.services.commons.exceptions" )
@EnableSolrRepositories(value = "com.ns.services.search", schemaCreationSupport = true, multicoreSupport =     true)
@EnableSwagger2
public class SearchServiceApplication 

    public static void main(String[] args) 
        SpringApplication.run(SearchServiceApplication.class, args);
    

    @Bean
    public HttpSolrClient solrClient() 
        return new HttpSolrClient("http://localhost:8983/solr");
    

    @Bean
    public SolrTemplate solrTemplate(SolrClient client) throws Exception 
        return new SolrTemplate(client);
    

    @Bean
    public Docket api() 
        return new Docket(DocumentationType.SWAGGER_2).select().apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any()).build();
    

    @Bean
    public SolrTemplate bookTemplate() throws Exception 
        SolrTemplate solrTemplate = new SolrTemplate(solrClient());
        solrTemplate.setSolrCore("demo");
        return solrTemplate;
    

BookRepository.java

@NoRepositoryBean
public interface BookRepository extends SolrCrudRepository<Book, String> 

    List<Book> findByName(String name);

BookService.java

public interface BookService 

    Book addBookToIndex(Book book);

BookServiceImpl.java

@Service
public class BookServiceImpl implements BookService 

    public BookServiceImpl() 
        super();
    

    @Autowired
    public BookRepository bookRepository;

    @Override
    public Book addBookToIndex(Book book) 
        return bookRepository.save(book);
    

尝试启动服务时出现异常跟踪：

【参考方案1】：

堆栈跟踪包含

没有符合条件的 bean 类型 [com.neighbourspoon.services.search.repositories.BookRepository]

这是因为 BookRepository 中的 @NoRepositoryBean 注释。你应该删除它。这仅用于自定义中间存储库。在这里，您直接扩展了 Spring Data 存储库。
