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

解决方案1

@Autowired

  SolrSubscriptionsRepository solrSubscriptionsRepository; 

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

  public Subscriptions getSubscriptions(@PathVariable Long subscriptionId) {

    solrSubscriptionsRepository.findSubscriptions(subscriptionId);

    return solrSubscriptionsRepository.findById(subscriptionId);

  }

解决方案2：

@Autowired

  SolrSubscriptionsRepository solrSubscriptionsRepository; 

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

  public Subscriptions getSubscriptions(@PathVariable Long subscriptionId) {

    solrSubscriptionsRepository.findSubscriptions(subscriptionId);

    return solrSubscriptionsRepository.findBySubscriptionId(subscriptionId);

  }

public interface SolrSubscriptionsRepository extends SolrCrudRepository{

 Subscriptions findBySubscriptionId(Long subscriptionId);

 }
