使用ElasticSearch启动Spring启动应用程序时出错

Question

我想对Spring数据使用ElasticSearch。我使用的是Spring 5、Spring Boot 2和ElasticSearch 7.4。Docker compose：

version: '2.1'

services:
  elasticsearch:
    container_name: "elasticsearch"
    image: docker.elastic.co/elasticsearch/elasticsearch:7.4.0
    volumes:
      - ./docker-data/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:ro
    ports:
    - 9200:9200
    - 9300:9300
    expose:
      - 9200
      - 9300
    environment:
    - discovery.type=single-node
    networks:
      - elastic
  kibana:
    image: docker.elastic.co/kibana/kibana:7.4.2
    container_name: kibana
    volumes:
      - ./docker-data/kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml:ro
    ports:
    - 5601:5601
    networks:
      - elastic
    depends_on:
      - elasticsearch

马文：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-elasticsearch</artifactId>
        <version>3.2.4.RELEASE</version>
    </dependency>

存储库：

@Repository
public interface AddressElasticRepository extends ElasticsearchRepository<Address, String> {

}

@Data
@Document(indexName = "fias", type = "address")
public class Address {
    @Id
    private String id;
    private String fullAddress;
}

配置：

import org.elasticsearch.client.RestHighLevelClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.client.ClientConfiguration;
import org.springframework.data.elasticsearch.client.RestClients;
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@Configuration
@EnableElasticsearchRepositories
public class Config {
    @Bean
    RestHighLevelClient elasticsearchClient() {
        final ClientConfiguration configuration = ClientConfiguration.builder()
                .connectedTo("localhost:9200")
                .build();
        return RestClients.create(configuration).rest();
    }

    @Bean
    ElasticsearchRestTemplate elasticsearchTemplate() {
        return new ElasticsearchRestTemplate(elasticsearchClient());
    }
}

和错误时启动应用程序：

引起：java.lang.NoSuchMEDError：org.springframework.http.HttpHeaders.（Lorg/springframe/util/MultiValueMap；）V

错误发生在Config::elasticsearch chClient方法中：. build（）；

发生了什么？

我的解决方案：配置：

@Configuration
@EnableElasticsearchRepositories(queryLookupStrategy = QueryLookupStrategy.Key.CREATE_IF_NOT_FOUND)
public class ElasticSearchConfig {
    @Bean
    RestHighLevelClient elasticsearchClient() {
        RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(
                new HttpHost("localhost", 9200, "http")
        ));
        return client;
    }

    @Bean
    ElasticsearchRestTemplate elasticsearchTemplate() {
        return new ElasticsearchRestTemplate(elasticsearchClient());
    }
}

maven（可能可以删除某些依赖项）：
