Is it possible to work with json type in java spring boot?

Is it possible to work with json type as in javascript without generating JSONOject in java spring boot? Is it possible to work with the { } format without creating a JSONObject?

Answer

JSON stands for “JavaScript Object Notation”. The Java Syntax does not support JSON. Therefore, we cannot use JSON to declare any object in Java like

MyAwesomeObject object = { "name": "foo", "age": 42 };

We can, however, convert a String that contains a JSON-string into a JSONObject. See this question by dogbane for details.

If we use, for example, jackson, we can convert a String to an object through jackson’s ObjectMapper:

final String json = "{ "name": "foo", "age": 42 }";
try {
    MyAwesomeObject object = objectMapper.readValue(json, MyAwesomeObject.class);
} catch (IOException e) {
    ...
}
