报错太长了，我提炼了一下，主要是说bean注入失败，各种service和controller全都寄了，后来看到里面有个elasticsearchRepository，又因为刚整合了elasticsearch，所以基本上可以确定问题就是出在elasticsearch上。

这里不得不说elasticsearch还是挺重视安全的，不能用root直接运行，要新建一个用户，并且把elasticsearch的拥有者转给这个用户才行。

然后我就先检查了配置文件，按理来说端口data，logs的路径什么的也都是默认的，基本上开箱即用。

没什么问题，于是我尝试用服务器本地访问服务器的9200端口，好家伙，果然不行。

然后我又去试了下curl

curl -X GET "119.91.222.49:9200/_cat/health?v"

果然也不行

最后千c万c最后发现了还是配置文件的问题，elasticsearch.yml有个这个

xpack.security.enabled: true

把这个改成false
