编码：配置文件
- 先准备好配置文件application.yml，内容如下，很简单，只有es的地址信息
elasticsearch:
# 多个IP逗号隔开
hosts: 127.0.0.1:9200
编码：配置类
- 首先把启动类写好，平平无奇的启动类BasicCrudApplication.java
@SpringBootApplication
public class BasicCrudApplication {
public static void main(String[] args) {
SpringApplication.run(BasicCrudApplication.class, args);
}
}
- 然后是配置类ClientConfig.java，这是本篇的关键，操作ES所需的ElasticsearchClient实例如何创建，ES的IP地址如何传入，全部写在这里了
package com.bolingcavalry.basic.config;
import co.elastic.clients.elasticsearch.ElasticsearchAsyncClient;
