这个错误应该是 在spring boot 启动时 检查了一下 es的健康状态 然后请求走的是 9200端口 

我的es 安装在服务器上了 没有安装到本地

之所以报错  localhost:9200 拒绝很正常 因为本地就没有 

解决方法：

    　　

spring:
    elasticsearch:
        rest:
          uris: ["http://192.168.10.68:9200"]

但是好像需要什么插件吧 好像是 head  我没有用这种方法解决 比较懒 没有再去安装插件 

直接用简单暴力方法解决

management.health.elasticsearch.enabled=false

直接就是不去检查  （这种还是不推荐的）
