I have a REST controller that returns a list of products like so:
Current output
[
{
"id":1,
"name":"Money market"
},
{
"id":2,
"name":"Certificate of Deposit"
},
{
"id":3,
"name":"Personal Savings"
}
]
In order to get things working with our JS grid library, I need the modify the response to look like:
Desired output
{ "data" :
[
{
"id":1,
"name":"Money market"
},
{
"id":2,
"name":"Certificate of Deposit"
},
{
"id":3,
"name":"Personal Savings"
}
]
}
Controller
@RequestMapping(value = "/api/products", method = RequestMethod.GET)
public ResponseEntity<?> getAllProducts() {
List<Product> result = productService.findAll();
return ResponseEntity.ok(result);
}
Is there an easy way to modify the JSON response using native Spring libraries?
You can put result object into a Map with key "data" and value as result.
map.put("data", result);
Then return the map object from the rest method.
return ResponseEntity.ok(map);
