我试图创建一个ESClient bean，如下所示。我正在使用弹簧启动，我的ElasticSearch已启动并在端口9200上运行
import org.springframework.stereotype.Component;
import org.apache.http.HttpHost;
import org.elasticsearch.action.index.IndexRequest;
import org.elasticsearch.action.index.IndexResponse;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.common.xcontent.XContentType;
import java.io.IOException;
import javax.annotation.PostConstruct;
@Component
public class EsClient {
private RestHighLevelClient esClient;
@PostConstruct
public void makeEsClient(){
esClient = new RestHighLevelClient(
RestClient.builder(
new HttpHost("localhost", 9200, "http")));
}
public void insertES(String message) throws IOException{
String jsonString = "{\"foo\":\"bar\"}";
IndexRequest indexRequest = new IndexRequest("product", "default").source(jsonString, XContentType.JSON);
IndexResponse indexResponse = esClient.index(indexRequest, RequestOptions.DEFAULT);
esClient.close();
}
}
启动应用程序时出现错误
创建名称为'esClient'的bean时出错：初始化方法的调用 失败嵌套的异常是java.lang.NoClassDefFoundError： org / elasticsearch / common / xcontent / DeprecationHandler

我对Java世界几乎是新手。在这里无法理解该问题。
