es when integrated with springboot frequently reported problem node es can not be found. There are two steps
network.host: 0.0.0.0
transport.tcp.port: 9300
http.port: 9200
Access to the network settings can be.
The most critical point is to see
introduced under spring-data-elasticsearch es which version of the package,
it requires these corresponding to the two versions, versions require kibana comprising the same version
