正在获取ElasticsearchStatusException和ElasticsearchResponseException？

Posted 2021-04-30

什么是ElasticsearchStatusException和ElasticsearchResponseException？

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

Caused by: org.elasticsearch.client.ResponseException: method [POST], host [http://HOST_NAME:PORT], URI [/user_context/_refresh?ignore_throttled=false&ignore_unavailable=false&expand_wildcards=open&allow_no_indices=true], status line [HTTP/1.1 400 Bad Request]

这是我尝试运行JavaSpring代码时得到的，

ERROR 26299 --- [           main] .d.e.r.s.AbstractElasticsearchRepository : failed to load elasticsearch nodes : ElasticsearchStatusException[method [HEAD], host [] ...............

pom.xml中的ElasticSearch版本：6.8.1，带有Spring Data Elasticsearch版本：3.2.6

远程服务器的ElasticSearch版本：6.2.2

我正在使用High Level Rest Client。

 @Override
 @Bean
 public RestHighLevelClient elasticsearchClient() {
 final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
     .connectedTo(elasticsearch_host + ":" + elasticsearch_port).build();
 return RestClients.create(clientConfiguration).rest();
}

春季版：2.2.4

答案

看起来您是elasticsearch主机是空的，如以下错误所示：

AbstractElasticsearchRepository : failed to load elasticsearch nodes : ElasticsearchStatusException[method [HEAD], host []

如果您使用9200端口在本地运行Elasticsearch，则可以使用以下方式创建Rest高级客户端：

[AbstractElasticsearchRepository：无法加载elasticsearch节点：ElasticsearchStatusException [方法[HEAD]，主机[]

import org.springframework.beans.factory.annotation.Autowired;@Configuration
static class Config {

      @Bean
      RestHighLevelClient client() {

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

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