1、先创建一个索引
curl -XPUT 'http://10.128.xx.yy:9200/wechat_data'
2、再创建mapping。 例如：
curl -XPOST 'http://10.128.XX.YY:9200/wechat_data/wechat_data/_mapping?pretty' -H 'Content-Type:application/json' -d' {"wechat_data": { "dynamic": "false", "properties": { "wechat_id": { "store": true, "type": "keyword" }, "creator": { "store": true, "type": "keyword" }, "groupId": { "store": true, "type": "keyword" }, "description": { "analyzer": "standard", "type": "text" }, "insert_time": { "format": "yyyy-MM-dd HH:mm:ss", "store": true, "type": "date" }, "reading": { "store": true, "type": "integer" }, "auto_id": { "store": true, "type": "long" }, "createDate": { "format": "yyyy-MM-dd HH:mm:ss", "store": true, "type": "date" } } }}'
