Producing JSON
JSON is everywhere Today. So let's jump into the train too and produce a JSON result. To do this, Vert.x provides:
- the
Jsonclass providing object mapping methods, - the
JsonObjectandJsonArrayallowing to create and manipulate JSON structures.
We are going to use this second approach to return something like:
{
"message": "hello"
}
This object can be easily created using: new JsonObject().put("message", "hello"). Then, we just need to encode this JSON structure into the HTTP response:
Producing JSON
package io.vertx.playground;
import io.vertx.core.Vertx;
import io.vertx.core.json.JsonObject;
public class HttpServerJsonExample {
public static void main(String... args) {
Vertx vertx = Vertx.vertx();
