我要评论elasticsearch这里安装在了windows下
安装elasticsearch，我这里选择的是最新版本（8.3.3）
下载地址： https://www.elastic.co/cn/downloads/elasticsearch
下载完之后解压文件夹
进入bin
双击执行
执行完成后会显示以下内容
-> elasticsearch security features have been automatically configured!
-> authentication is enabled and cluster connections are encrypted.
-> password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
01avmpeg7*bwmggaxnv0
-> http ca certificate sha-256 fingerprint:
1ae7d35f3165a808fe6b55fc6090ff938dadc55ac86b3330548ef6b9a896f5b8
-> configure kibana to use this cluster:
* run kibana and click the configuration link in the terminal when kibana starts.
* copy the following enrollment token and paste it into kibana in your browser (valid for the next 30 minutes):

-> configure other nodes to join this cluster:
* on this node:
- create an enrollment token with `bin/elasticsearch-create-enrollment-token -s node`.
- uncomment the transport.host setting at the end of config/elasticsearch.yml.
- restart elasticsearch.
* on other nodes:
- start elasticsearch with `bin/elasticsearch --enrollment-token <token>`, using the enrollment token that you generated.
其中，需要注意两处
elastic为登录账号，01avmpeg7*bwmggaxnv0为登录密码，密码是随机生成，不可直接复制本文中的。
安装完成后，进入config文件夹
打开elasticsearch.yml文件
访问访问localhost:9200，出现下图，则成功
jeecgboot的配置
因为在application-dev.yml的配置中，没有配置登录的账户和密码，所以这里我们选择elasticsearch为免密登录
完成以上配置，直接启动项目即可
