consuming array of json object in jersey in java

Question

to consume a single object in jersey I have my method like this

 @POST
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
@Produces(MediaType.APPLICATION_JSON)
public Response postPerson(MultivaluedMap<String, String> personParams){
    ResponseBuilder response = Response.ok();
    return response.build();
    }

    its working well.

my doubt is how can i consume list of objects in jersey

    some thing like this 



 @POST
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
@Produces(MediaType.APPLICATION_JSON)
    public Response postPerson(List<Person> person){

     ResponseBuilder response = Response.ok();
    return response.build();

      }

I did some googling but didn't found any working example.

Answer 1

It seems you want to pass the form data as list:

@POST
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
@Produces(MediaType.APPLICATION_JSON)
    public Response postPerson(@FormParam("person") List<String> person){

     ResponseBuilder response = Response.ok();
    return response.build();

      }

<html><body>
<form action="http://localhost:9998/myresource" method="POST">
<input type="checkbox" name="person" value="a">A</input>
<input type="checkbox" name="person" value="b">B</input>
<input type="checkbox" name="person" value="c">C</input>
<input type="submit">OK</input>
</form>
</body></html>

similarly for Person object, you have to map the diffrent property so that it can post the list of person Source: JERSEY RESTful - How to work with multiselect checkboxes? this has worked for me.

Answer 2

I am using jersy as the RESTful webservice and angularJS to post all the todo objects at the same time use your person object to update data at the same time

//Define an angular module for our app
var sampleApp = angular.module('sampleApp', ['ngRoute','ngResource']);

sampleApp.config(['$routeProvider',
  function($routeProvider) {
    $routeProvider.
      when('/AddNewOrder', {
        templateUrl: 'add_order.jsp',
        controller: 'AddOrderController'
    }).
when('/TestArray', {
        templateUrl: 'list.html',
        controller: 'TestArrayController'
    }).    



      }).
      otherwise({
        redirectTo: '/AddNewOrder'
      });
}]);
sampleApp.controller( 'TestArrayController', function ( $scope, $location,$http,$resource) {

var array=new Array();
var postObject1 = new Object();
postObject1.description = "testDesc1";
postObject1.summary = "testSummary1";
array.push(postObject1);
var postObject2 = new Object();
postObject2.description = "testDesc2";
postObject2.summary = "testSummary2";
array.push(postObject2);

$http.post("/AngularJS/JerseyWebService/todo/arrayTest", array).success(function(data){
    //Callback function here.
    //"data" is the response from the server.
    $scope.updateMessage=data;
});
