如何在spring-data-elasticsearch中创建索引后更新索引设置

import org.elasticsearch.action.admin.indices.settings.put.UpdateSettingsRequest;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.common.settings.Settings;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;
import org.springframework.stereotype.Component;

@Component
public class IndexSettingsUpdater {

    @Autowired
    private RestHighLevelClient restHighLevelClient;

    @Autowired
    private ElasticsearchRestTemplate elasticsearchRestTemplate;

    public void updateIndexSettings(String indexName) throws IOException {
        Settings indexSettings = Settings.builder()
                .put("index.number_of_replicas", 2)
                .put("index.refresh_interval", "5s")
                .build();

        UpdateSettingsRequest request = new UpdateSettingsRequest(indexName)
                .settings(indexSettings);

        restHighLevelClient.indices().putSettings(request, RequestOptions.DEFAULT);
        elasticsearchRestTemplate.refresh(indexName);
    }
}
