尝试使用 ElasticSearch 存储和获取一些数据

Question

我有这个使用 ElasticSearch 的小配置，但由于我想存储一些数据，我收到以下错误：repository.save(new FileProperty("12dW", 123.123, "hii")); elasticSearch 使用 docker 在端口 9200 上运行

    Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.elasticsearch.UncategorizedElasticsearchException: Elasticsearch exception [type=illegal_argument_exception, reason=request [/index/_refresh] contains unrecognized parameter: [ignore_throttled]]; nested exception is ElasticsearchStatusException[Elasticsearch exception [type=illegal_argument_exception, reason=request [/index/_refresh] contains unrecognized parameter: [ignore_throttled]]]] with root cause

org.elasticsearch.ElasticsearchStatusException: Elasticsearch exception [type=illegal_argument_exception, reason=request [/index/_refresh] contains unrecognized parameter: [ignore_throttled]]

FileRepository.java

@Repository

public interface FileRepository extends ElasticsearchRepository<FileProperty, String> {

    List<FileProperty> findByName(String filename);

}

文件属性.java

@Document(indexName = "index", type = "user", shards = 2)
@Data
@AllArgsConstructor
@NoArgsConstructor
public class FileProperty {
    @Id
    private String id;
    private double filesize;
    private String name;
}

Config.java

公共类配置{

@Bean
public RestHighLevelClient client() {
    ClientConfiguration clientConfiguration
            = ClientConfiguration.builder()
            .connectedTo("localhost:9200")
            .build();

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

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

}

application.yml

      # Local Elasticsearch config
        spring.data.elasticsearch.repositories.enabled=true
        spring.data.elasticsearch.cluster-nodes=localhost:9200
        spring.data.elasticsearch.cluster-name=elasticsearch
        
        elasticsearch.index.name=index
        elasticsearch.user.type=user

Answer 1

您似乎正在使用版本 6 或 7 中的 Elasticsearch 客户端库来访问 Elasticsearch 5 集群。

请查看compatibility matrix 哪个版本的 Spring Data Elasticsearch 和 Spring Boot 与哪个版本的 Elasticsearch 一起使用。

另一件事：你应该使用

spring.elasticsearch.server=localhost:9200

配置您的 Elasticsearch 集群的运行位置并删除这两行：

spring.data.elasticsearch.cluster-nodes=localhost:9200
spring.data.elasticsearch.cluster-name=elasticsearch

这些是传输客户端的配置值，如果设置了这些属性，Spring Boot 将配置一个。
