I am trying to return a response from the back end using java where the response is a list of json values.
Is it possible to return the data in this format?
{"someKey": someValue},
{"someKey2": someValue},
{"someKey2": someValue}
I noticed that json values are always returned wrapped in an array like this
[
{"someKey": someValue},
{"someKey2": someValue},
{"someKey2": someValue}
]
I was asked to return the json data without being in an array and I am having trouble doing that. Is it even possible to return a list of json objects without being wrapped in an array? This is in java using the ObjectMapper class
CodePudding user response:
List of json objects not wrapped in an array []
is a invalid json format and will give you error: multiple JSON root elements
Possibly you can modify the result to this JSON format?
{
"somekey": somevalue,
"someKey2": someValue,
"someKey3": someValue,
}
CodePudding user response:
As others have pointed out, a list of objects without the wrapping array.would be invalid JSON.
However, if you really must return that, you could arrange to get the JSON as a String, and then use String methods, of your choice (e.g. substring) to remove the square braces, and then return that. Ultimately, a JSON is a String.
