spring数据elasticsearch：设置和映射配置，注释不起作用

Question

我正在使用带有Spring启动的嵌入式elasticsearch，并且我试图使用注释来配置设置和映射。我遵循了本教程，其中解释了如何实现对多个字段的搜索。无论如何，我已经在我的文档实体中定义了settings.json和mappings.json，如下所述，但它似乎没有读取文件，因为卷曲映射不会返回文件中定义的相应配置。

索引由spring批处理执行。它从数据库读取数据并将其写入elasticsearch。这非常有效。

当我向http://localhost:9200/profile/_search发出POST请求时，我没有得到任何结果（应该返回7个项目）：

{
   "size": 10,
   "query": {
       "match": {
       "_all": {
           "query": "user male",
           "operator": "and"
       }
    }
  }
}

如果我将查询更改为“user5”，它将返回具有此昵称的用户。

如果有人能给我一个提示，我将不胜感激。配置有什么问题？

配置

@Configuration
@EnableElasticsearchRepositories(basePackages ="com.company.searchengine.repository")
public class ElasticSearchConfiguration {
    @Value("${elasticsearch.clustername}")
    private String esClusterName;

    @Bean
    public ElasticsearchOperations elasticsearchTemplate() throws IOException {
        return new ElasticsearchTemplate(nodeBuilder().local(true).clusterName
            (esClusterName).node()
            .client());
    }
}

文档

@EqualsAndHashCode(of = "uuid")
@ToString(exclude = "uuid")
@NoArgsConstructor(onConstructor = @__({@JsonCreator}))
@Getter
@Setter
@Document(indexName = "profiles", type = "profile", createIndex = false)
@Setting(settingPath = "/settings/settings.json")
@Mapping(mappingPath = "/mappings/mappings.json")
public class IndexedProfile {
    @Id
    @NonNull
    private String uuid;
    @NonNull
    //@Field(index = FieldIndex.not_analyzed, type = FieldType.String)
    private String nickname;
    @NonNull
    //@Field(index = FieldIndex.not_analyzed, type = FieldType.String)
    private String gender;
    //@Field(index = FieldIndex.not_analyzed, type = FieldType.String)
    private String about;
    private GeoPoint location;
    @Field(type = FieldType.Date, format = DateFormat.year_month_day)
    private Date birthdate;
}

批量作业

@Override
public void write(List<? extends IndexedProfile> items) throws Exception {
    List<IndexQuery> indexQueries = items.stream()
            .map(item -> new IndexQueryBuilder().withObject(item).withId(String.valueOf(item.getUuid())))
            .map(builder -> builder.withType(DOCUMENT_TYPE))
            .map(builder -> builder.withIndexName(INDEX_NAME + runId))
            .map(IndexQueryBuilder::build)
            .collect(Collectors.toList());

    this.elasticsearchTemplate.bulkIndex(indexQueries);
}

                "type": "string",
                "index": "not_analyzed"
           },
           ....

    }

@Setting(settingPath = "studentdoc_setting_index_mapping_type_overlayadjacency.json")
public class StudentDoc {
}

Answer 2

设置和映射JSON结构不正确，请尝试使用以下参考示例进行调整：

映射：https://github.com/spring-projects/spring-data-elasticsearch/tree/master/src/test/resources/mappings

设置：https://github.com/spring-projects/spring-data-elasticsearch/tree/master/src/test/resources/settings

Answer 3

根据org.springframework.data.elasticsearch.core.mapping.SimpleElasticsearch chPeristentEntity，设置createIndex=false将导致框架不创建索引和映射！所以您应该删除该设置或将其设置为true。
