1. 该公共包提供了transport和jest的ES服务接口
2. 如果只需要transport请使用elasticsearch-transport-starter

#配置示例
spring:
  elasticsearch:
    cluster-name: jkzl #默认即为elasticsearch  集群名
    cluster-nodes: 172.19.103.45:9300,172.19.103.68:9300 #配置es节点信息，逗号分隔，如果没有指定，则启动ClientNode
    client-transport-sniff: false #是否开启嗅探
    jest:
      uris: http://172.19.103.45:9200,http://172.19.103.68:9200 #jest的uri
      connection-timeout: 60000 #Connection timeout in milliseconds.
      multi-threaded: true #Enable connection requests from multiple execution threads.
