2.8. 使用 JSON API 进行 JSON 处理(JSON-P)

JsonObject obj = Json.createObjectBuilder().add("name", "Bill").build();

{
  "name":"Bill"
}

JsonArray array =
  Json.createArrayBuilder()
    .add(Json.createObjectBuilder().add("name", "Bill").build())
    .add(Json.createObjectBuilder().add("name", "Monica").build()).build();

[
  {
  "name":"Bill"
  },
  {
  "name":"Monica"
  }
]

JsonObject obj = Json.createObjectBuilder().add("name", "Bill").build();

JsonArray array =
  Json.createArrayBuilder()
    .add(Json.createObjectBuilder().add("name", "Bill").build())
    .add(Json.createObjectBuilder().add("name", "Monica").build()).build();

JsonStructure sObj = (JsonStructure) obj;
JsonStructure sArray = (JsonStructure) array;

@Path("object")
@POST
@Produces("application/json")
@Consumes("application/json")
public JsonObject object(JsonObject obj) {
  // do something
  return obj;
 }

@Path("array")
@POST
@Produces("application/json")
@Consumes("application/json")
public JsonArray array(JsonArray array) {
  // do something
  return array;
}

@Path("structure")
@POST
@Produces("application/json")
@Consumes("application/json")
public JsonStructure structure(JsonStructure structure) {
  // do something
  return structure;
}

WebTarget target = client.target(...);
JsonObject obj = Json.createObjectBuilder().add("name", "Bill").build();
JsonObject newObj = target.request().post(Entity.json(obj), JsonObject.class);
