es Spring boot 整合elesticsearch报错 解决思路

1. 报错类型
   报错None of the configured nodes are available

2. 云服务部署的es版本 为5.6.16

3. 项目依赖

<parent>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-parentartifactId>
        <version>2.1.6.RELEASEversion>
        <relativePath/> 
    parent>
         <dependency>
            <groupId>org.springframework.datagroupId>
            <artifactId>spring-data-elasticsearchartifactId>
        dependency>

4. 项目配置

spring.data.elasticsearch.cluster-name=elasticsearch
spring.data.elasticsearch.cluster-nodes=172.30.0.8:9300
spring.data.elasticsearch.repositories.enabled=true

通过http 的方式是 直接访问9200端口是可以访问的 http://172.30.0.8:9200 显示内容为

    "cluster_uuid": "Gcrn0TsYStW_jNl6fsxdAQ",
    "version": {
   
        "number": "5.6.16",
        "build_hash": "3a740d1",
        "build_date"
