我的配置：

@Configuration
@EnableElasticsearchRepositories(
    basePackages = { "com.aj.new.repositories" })
public class ElasticDataSourceConfig {

    @Bean
    public RestHighLevelClient client() {

        ClientConfiguration clientConfiguration = ClientConfiguration.builder()
            .connectedTo("localhost:9200")
            .build();

        return RestClients.create(clientConfiguration).rest();
    }

    @Bean
    public ElasticsearchRestTemplate elasticsearchTemplate() {
        return new ElasticsearchRestTemplate(client());
    }
}

文档：

@Document(indexName = "provider_search")
public class Provider {

    @Id @Field
    private Long id;

    @Field(type = FieldType.Keyword)
    private String search;

    @Field(name = "ProviderName", type = FieldType.Keyword)
    private String providerName;

    @Field(name = "Address")
    private String address;

    @Field(name = "City")
    private String city;

    @Field(name = "State")
    private String state;

   ...getters...
   ...setters...
}

用法：

@Service
public class MySearchService {
    
  @Autowired
  private ElasticsearchRestTemplate elasticsearchRestTemplate;

  public List<Provider> searchProvidersUsingElastic(final String 
    providerName, final AddressSearchCriteriaBean addressCriteria) {

    final NativeSearchQueryBuilder searchQueryBuilder = new 
      NativeSearchQueryBuilder();
    
    if (providerName != null) {
      final String regex = ".*" + providerName + ".*";
      searchQueryBuilder.withQuery(regexpQuery("providerName", regex));
    }
    
    if (addressCriteria.getState() != null) {
      searchQueryBuilder.withFilter(matchQuery("state", 
        addressCriteria.getState())
       .fuzziness(Fuzziness.ONE));
    }   
    
    SearchHits<Provider> articles = 
      elasticsearchRestTemplate.search(searchQueryBuilder.build(), 
      Provider.class, IndexCoordinates.of("provider_search"));
    
    final List<Provider> providers = articles
      .stream()
      .map(SearchHit::getContent)
      .collect(Collectors.toList());
    
    return providers;
  }
}

在使用或不使用过滤器进行调试时，我得到的提供者只填充了他们的 ID 字段。像“搜索”、“状态”等所有其他字段都是空的。

这是我在 ElasticSearch 世界中的第一次冒险，我不确定这里出了什么问题。任何帮助表示赞赏。

请注意，出于测试目的，我没有在 Java 端映射 Provider 的每个字段。如果这有问题，请告诉我。

第二次更新：

我已更改 Provider 文档以按原样映射字段名称。尽管如此，除了 id 之外的所有内容仍然为空。

@Document(indexName = "provider_search")
    public class Provider {
    
        @Id
        private Long id;
    
        private String search;
    
        private String ProviderName;
    
        private String Address;
    
        private String City;
    
        private String State;
    
       ...getters...
       ...setters...
    }

更新：

原来 Elasticsearch 索引有一个错误，我在 Java 端映射的字段在 ES 索引上不可用。它已被修复，我看到所有值都正确填充。

您在使用属性名称（Provider实体的属性）和相应的字段名称（Elasticsearch 中的名称）时存在不一致。

您的属性以小写字母开头，然后是驼峰式 ( providerName, )，对于 Spring Data Elasticsearch，您将它们定义为映射到以大写字母 ( , )state开头并带有注释的版本。因此 Spring Data Elasticsearch 期望 Elasticsearch 返回一个值，然后将其存储在属性中。ProviderNameState@FieldProviderNameproviderName

索引中的字段名称是否以大写字母开头？http://localhost:9200/provider_search/_mappings 显示什么？这是一个猜测，因为您没有显示 Elasticsearch 返回的内容，但会解释您的错误。
