在Elasticsearch服务器中索引（存储）文档时，我们的应用程序encoutner超时异常。它不经常发生，但大约每天一次。这是详细信息。

pom.xml

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
    <version>6.0.0</version>
</dependency>

初始化

@Bean
public RestHighLevelClient buildHighLevelClient() {
    RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(httplist.toArray(new HttpHost[]{})));
    return client;
}
