elasticsearch批量插入数据的时候出现java.net.SocketTimeoutException: 30,000 milliseconds timeout on connection

elasticsearch每次都批量插入几万数据量，然后就会出现下列问题。看这个问题应该是配置的问题

解决办法（我仅处理elasticsearch7.8.0版本的，可以看到下面的方法出现的是RestHighLevelClient高级客户端的）：

创建下面列举的配置类即可，然后相应修改下自己的需要的时间

import org.apache.http.HttpHost;
import org.apache.http.client.config.RequestConfig;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestClientBuilder;
import org.elasticsearch.client.RestHighLevelClient;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
@Configuration
public class ElasticSearchClientConfig {
 
    @Bean
    @Qualifier("highLevelClient")
    public RestHighLevelClient restHighLevelClient() {
        // RestHighLevelClient highLevelClient = new RestHighLevelClient(
        // RestClient.builder(new HttpHost("127.0.0.1", 9200, "http")));
 
        RestHighLevelClient highLevelClient = new RestHighLevelClient(
                RestClient.builder(new HttpHost("127.0.0.1", 9200, "http"))
                        .setRequestConfigCallback(new RestClientBuilder.RequestConfigCallback() {
                            // 该方法接收一个RequestConfig.Builder对象，对该对象进行修改后然后返回。
                            @Override
                            public RequestConfig.Builder customizeRequestConfig(
                                    RequestConfig.Builder requestConfigBuilder) {
                                return requestConfigBuilder.setConnectTimeout(5000 * 1000) // 连接超时（默认为1秒）
                                        .setSocketTimeout(6000 * 1000);// 套接字超时（默认为30秒）//更改客户端的超时限制默认30秒现在改为100*1000分钟
                            }
                        }));// 调整最大重试超时时间（默认为30秒）.setMaxRetryTimeoutMillis(60000);
 
        return highLevelClient;
    }
 
}
RestClientBuilder支持同时提供一个RequestConfigCallback和一个HttpClientConfigCallback，你可以定制 the Apache Async Http Client 公开的配置。这两个回调函数可以修改某些特定的行为，而不会覆盖RestClient初始化的所有其他默认配置。 

使用elasticsearch查询百亿级数据必然会影响查询的速度但是es与客户端的的默认响应时间只有30秒，查询大量的数据时30秒的时间一般都不够用。
