If we have a POJO class, then we can map it with some incoming JSON. I am struggling to find out a way by which I can just have all plain json value inside.

For ex.

```
{
    "macro_tasks": [
        {
            "id": "cc5cee68-c1e5-4396-987b-c68559399186",
            "label": "consi-1",
            "name": "Consi 1",
            "project_id": "82d1e463-1bb1-42d3-9adc-9e0d5848d139",
            "creator_id": null,
            "created_at": null,
            "updated_at": null,
            "meta_data": {
                "key1": "value1",
                "key2": 321
          }
        }
    ]
}

```

Here `meta_data` is of JSON type which can keep changing its values inside. So I cannot map it with some POJO class.

```
public class MacroTask {

    private UUID id;
    private String label;
    private String name;

    private UUID projectId;

    private UUID creatorId;

    private String createdAt;

    private String updatedAt;

    private <some data type> meta_data;

//getter and setter

```

Is there any way to get plain JSON data and use it in code and dump into DB [we are using PostgreSQL, which supports `jsonb` type.]
