java构造函数TransportClient（）未定义？

Question

我正在使用mongo db进行弹性搜索。导入传输客户端时，它会显示

The constructor TransportClient() is undefined.

我将其配置如下：

package com.appointment.api.mobile.config;

import javax.annotation.Resource;

import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.common.transport.TransportAddress;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@Configuration
@PropertySource(value = "classpath:elasticsearch.properties")
@EnableElasticsearchRepositories(basePackages = "com.appointment.api")
public class ElasticsearchConfiguration {

    @Resource
    private Environment environment;

    @Bean
    public Client client() {
        TransportClient client = new TransportClient();
     /*   TransportAddress address = new InetSocketTransportAddress(environment.getProperty("elasticsearch.host"), Integer.parseInt(environment.getProperty("elasticsearch.port")));
        client.addTransportAddress(address); */
        return client;
    }

    @Bean
    public ElasticsearchOperations elasticsearchTemplate() {
        return new ElasticsearchTemplate(client());
    }


}

依赖项：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

项目：

Spring boot maven project.

根据dochere，TransportClient没有公共默认构造函数，您需要执行以下操作：

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
