Json 字符串到 Json 使用 Java 和 Jolt

Question

I have a json string eg.

 { "value": "{\"userSuspended\":false}" }

What would be the correct Jolt spec to map 'userSuspended' to 'state'?

Answer 1

It needed two transforms and a Javaclass to map the key/value:

1. Shift "Value":"Value"
2. Map the keys 'userSuspended' and 'false' through a javaclass to key/value pairs
3. Shift the output to "userSuspended":"State"

Answer 2

One way of doing it is to split the value and save what you wanted to state.

[
  {
    "operation": "modify-overwrite-beta",
    "spec": {
      "stateArray": "=split('\"',@(1,value))"
    }
  },
  {
    "operation": "shift",
    "spec": {
      "stateArray": {
        "1": "state"
      }
    }
  }
]
