Merge two JSON Objects using json-smart as provider

Suppose you have the following JSON documents previously loaded using json-smart as provider:

• JSONObject json1

  {
    "agents": [
      {
        "class": "Agent1",
        "interval": "1 minute"
      },
      {
        "class": "Agent2",
        "interval": "2 minutes"
      }
    ]
  }

• JSONObject json2

  {
    "agents": [
      {
        "class": "Agent2",
        "interval": "2 hours"
      },
      {
        "class": "Agent3",
        "interval": "3 minutes"
      }
    ]
  }

1. Create a JsonMerger of type net.minidev.json.JSONObject with the JsonSmartJsonProvider:

import net.minidev.json.JSONObject;
import net.obvj.jsonmerge.*;
import net.obvj.jsonmerge.provider.JsonSmartJsonProvider;
...
JsonMerger<JSONObject> merger = new JsonMerger<>(new JsonSmartJsonProvider());

2. Merge both objects, defining a distinct key class to identify each object in the agents list:

JSONObject merged = merger.merge(json1, json2,
        JsonMergeOption.distinctKey("$.agents", "class"));

💡 The JSON generated by the merge operation will be as follows:

{
  "agents": [
    {
      "class": "Agent1",
      "interval": "1 minute"
    },
    {
      "class": "Agent2",
      "interval": "2 minutes"
    },
    {
      "class": "Agent3",
      "interval": "3 minutes"
    }
  ]
}
