找不到类型的属性

Question

当运行我的代码从 Solr 获取数据时，它无法编译并出现异常：

Caused by: org.springframework.data.mapping.PropertyReferenceException: No property findSubscriptions found for type Subscriptions!

我没有看到命名不一致或缺少方法。代码用于从 Solr 获取数据。我已经创建了一个文档，并且 Solr 已启动并在“ http://localhost:8983/solr/ ”上运行

1)

      @RestController

      public class SubscriptionsController {

      @Autowired

      SolrSubscriptionsRepository solrSubscriptionsRepository; 

      @GetMapping("/subscriptions/{subscriptionId}")

      public Subscriptions getSubscriptions(@PathVariable Long subscriptionId) {

        solrSubscriptionsRepository.findSubscriptions(subscriptionId);

        return solrSubscriptionsRepository.findSubscriptions(subscriptionId);

      }

2)

     @SolrDocument(collection= "Subscriptions")

     public class Subscriptions {

     @Id

     @Indexed(name="subscription_id", type="long")

     private Long subscriptionId;

     @Indexed(name="subscription_query", type="string")

     private String subscriptionQuery;

     @Indexed(name="subscription_type", type="string")

     private String subscriptionType;

     } 

3)

     public interface SolrSubscriptionsRepository extends 

     SolrCrudRepository<Subscriptions, Long>{

     Subscriptions findSubscriptions(Long subscriptionId);

     }

4)

      @Configuration

      @EnableSolrRepositories(basePackages="com.test.repository")

      @ComponentScan

      public class SolrConfig {

      @Value("spring.data.solr.host") String solrURL;

      @Bean

      public SolrClient solrClient() {

        return new HttpSolrClient.Builder(solrURL).build();

      }

      @Bean

      public SolrTemplate solrTemplate(SolrClient solrClient) throws Exception {

        return new SolrTemplate(solrClient);

        }

      }

5) application.properties

spring.data.solr.host=http://localhost:8983/solr/
