How does nIFi implement JSON parsing and merging

[#1]

mqtt -> flattenjosn -> spiltjson -> evajsonpath

Data received by MQTT:

{"device_name":"Device37","device_id":"GanghuaLianXian","date":"2021-09-24 17:45:44","sensor":[{"sensor_id":"Data05_37_alarm","value ":"0"},{"sensor_id":"Data06_37_alarm","value":"0"},{"sensor_id":"Data07_37_alarm","value":"0"},
],"status":1 }

Parsing json:  

"sensor":[{"sensor_id":"Data05_37_alarm","value":"0"},{"sensor_id":"Data06_37_alarm","value":"0"},{"sensor_id":"Data07_37_alarm", "值":"0"},
],

Merge the json:

{"device_name":"Device37","device_id":"GangHuaLianXian","date":"2021-09-24 17:45:44","sensor_id":"Data05_37_alarm","value":"0"} ,

{"device_name":"Device37","device_id":"GangHuaLianXian","date":"2021-09-24 17:45:44","sensor_id":"Data06_37_alarm","value":"0"} ,

{"device_name":"Device37","device_id":"GangHuaLianXian","date":"2021-09-24 17:45:44","sensor_id":"Data07_37_alarm","value":"0"} ,

How to achieve?

我是这样做的.

EvaluateJsonPath

SplitJson

ExtractText

ReplaceText

就是不知道怎么把splitjson里面的数据用ReplaceText合并.
