[FIXED] How to show data without ID in Spring

Issue

I am showing some data to the user:

{
"id": 3,
"name": "AB:11",
"description": "AB:11 is an Imperial Black Barley Wine brewed with ginger, black raspberries and chipotle peppers. A 12.8% rollercoaster of ginger zestiness and chipotle smokiness, all bound together with dark berry tartness and the decadent residual body of a Black Barley Wine.",
"method": {
    "id": 3,
    "mash_temp": [
        {
            "id": 6,
            "temp": {
                "value": 68,
                "unit": "celsius"
            }
        }
    ]
}

}

But, I want to show it without "method" I only need to show what is inside "mesh_temp" field,so it would be something like this:

"id": 3,
"name": "AB:11",
"description": "AB:11 is an Imperial Black Barley Wine brewed with ginger, black raspberries and chipotle peppers. A 12.8% rollercoaster of ginger zestiness and chipotle smokiness, all bound together with dark berry tartness and the decadent residual body of a Black Barley Wine.",
"mash_temp": [
   {
       "temp": {
       "value": 68,
       "unit": "celsius"
        }
   }
  ]
}

Also, like you can see in first example I don't want to show id of the mesh_temp

Those are my Entities:

• Beer: Beer class
• Method: Method class
• Mash Temp: MashTemp class
• Temp: Temp class

So just to summarize: I want to show only: id, name, description and mash_temp field (without id). Any advices how to do this?

Solution

The simplest way is to create a DTO that is used in the response on your API with exactly the attributes you want. This is in fact a suggested pattern exactly because of use cases similar to this one: when your internal model is different from the model you want to make available via your API.
