Spring Boot没有配置的节点可用的问题 [英] None of the configured nodes are available issue with spring boot

问题描述

你好朋友，我正在使用弹性搜索开发Spring Boot项目，我已经在本地计算机上设置了弹性搜索，并且已经安装了 Head 弹性搜索插件。我的弹性搜索设置正确，显示绿色标志。
我的项目中的application-dev.yml文件如下：

Hi friends i am developing spring boot project with elastic search i have setup elastic search on local machine and i have installed Head plugin in elastic search . My elastic search is setup correctly showing green sign. My application-dev.yml file in my project is as follows:

    port: 8080

    profiles:
        active: dev
    datasource:

弹性搜索服务正在我的机器上运行，但是当我尝试保存实体时，我的代码先将实体保存在mysql中，然后在弹性搜索中使用g 弹性搜索存储库，但是在将实体保存到弹性中时会引发错误：

Elastic search service is running on my machine but when i try to save entity first my code save entity in mysql then in elastic search using elastic search repository but on saving entity into elastic it throws error:
