这段代码使用了Elasticsearch的Java High Level REST Client，需要导入以下依赖：

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
    <version>7.12.0</version>
</dependency>

同时需要导入以下包：

import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.action.bulk.BulkRequest;
import org.elasticsearch.action.bulk.BulkResponse;
import org.elasticsearch.action.index.IndexRequest;
import org.elasticsearch.common.xcontent.XContentFactory;

另外，需要注意的是，这段代码是使用POST方法来插入数据到Elasticsearch中，因此需要在Controller类上添加`@RestController`和`@RequestMapping`注解，同时在该方法上添加`@PostMapping`注解以映射HTTP POST请求。
