無法連接到彈性搜索的java與springboot，說找不到xxx.jar

Question

我想快速學習elasticsearch，我知道使用springboot是快速的，所以我創建了一個項目與springboot，然後，我看彈性搜索的API，但最後，它拋出了一個例外。

我只是想學習elasticSearch。
我不知道是否衝突罐。
我該怎麼辦？

package com.test.Search; 

import java.net.InetAddress; 
import java.net.UnknownHostException; 

import org.elasticsearch.common.settings.Settings; 
import org.elasticsearch.common.transport.InetSocketTransportAddress; 
import org.elasticsearch.transport.client.PreBuiltTransportClient; 
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.ResponseBody; 


@Controller 
@EnableAutoConfiguration 
public class AppController { 

    @RequestMapping("/") 
    @ResponseBody 
    String home() throws UnknownHostException { 

     PreBuiltTransportClient client = new 
PreBuiltTransportClient(Settings.EMPTY); 
     client.addTransportAddress(new 
InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300)); 
     client.close(); 

     return "Hello World!"; 
    } 

    public static void main(String[] args) throws Exception { 
     SpringApplication.run(AppController.class, args); 
    } 
}
