elasticsearch的模糊查询

使用elasticsearch首先创建索引命令行创建的方法：curl -XPUT 127.0.0.1:9200/ikblockchain?pretty -d'{"mappings":{"server_log":{"properties":{"addTime":{"type":"date","format":"yyyy-MM-dd HH:mm:ss"},"appName":{"type":"...

使用elasticsearch首先创建索引
命令行创建的方法：

curl -XPUT 127.0.0.1:9200/ikblockchain?pretty -d  '{"mappings":{"server_log":{"properties":{"addTime":{"type":"date","format":"yyyy-MM-dd HH:mm:ss"},"appName":{"type":"text"},"blockHeight":{"type":"long"},"cropId":{"type":"text"},"filePath":{"type":"text","analyzer":"whitespace"},"message":{"type":"keyword"},"rawContent":{"type":"text","analyzer":"whitespace"},"rawJsonContent":{"type":"text"},"timestamp":{"type":"long"},"toolType":{"type":"text"},"transactionId":{"type":"long"}}}}}' -H "Content-Type: application/json"

这个命令注意：后边 -H “Content-Type: application/json” 很重要，不然会报错
通过postman创建
在这里插入图片描述
图中server_log是封装对象的表名
