原文链接：https://blog.csdn.net/magic_1024/article/details/103246719

版本：springboot 2.2.2 + es 6.8.4

如果你的 es 和 redis 版本冲突了，试试更高版本的 netty:

	<!-- 解决 mq 和 es 的冲突 -->
	   <dependency>
	       <groupId>io.netty</groupId>
	       <artifactId>netty-all</artifactId>
	       <version>4.1.68.Final</version>
	   </dependency>

3.创建Elasticsearch配置类

package com.example.demo.config;

import lombok.extern.slf4j.Slf4j;
import org.elasticsearch.client.Client;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.TransportAddress;
import org.elasticsearch.transport.client.PreBuiltTransportClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

import java.net.InetAddress;

@Slf4j
@Configuration
@EnableElasticsearchRepositories(basePackages = "com.example.demo.dao")
public class ElasticsearchConfig {
   

    @Value("${elasticsearch.host}")
    private String esHost;

    @Value("${elasticsearch.port}")
    private int esPort;
