JQuery Full Calendar with Spring MVC ..无法调用 Controller 来获取JSON对象

Question

我正在尝试使用 JQuery Full Calendar以及 Spring MVC + Freemarker。

我做了一个类似 that 的演示.

目标:我需要调用 Controller 来获取包含要在日历上呈现的事件的 JSON 对象。

问题: 我有以下 freemarker，它应该转到 Controller 并获取要渲染的 JSON 对象，但它没有去？!!

终于，我成功了:) 我使用 $.getJSON 来获取 json 对象。

   $(document).ready(function() {
            var date = new Date();
            var d = date.getDate();
            var m = date.getMonth();
            var y = date.getFullYear();
          $.getJSON('[@spring.url '/vacation/getVacation'/]', function (data) {
            var calendar = $('#calendar').fullCalendar({
                header: {
                    left: 'prev,next today',
                    center: 'title',
                    right: 'month,agendaWeek,agendaDay'
                },
                selectable: true,
                selectHelper: true,
                select: function(start, end, allDay) {
                    var title = prompt('Event Title:');
                    if (title) {
                        calendar.fullCalendar('renderEvent',
                        {
                            title: title,
                            start: start,
                            end: end,
                            allDay: allDay
                        },
                                true // make the event "stick"
                                );
                    }
                    calendar.fullCalendar('unselect');
                },
                editable: true,
                events:[data]
            });
         });
        });

Java Controller :

@RequestMapping(value = "/vacation/getVacation", method = RequestMethod.GET)
    public
    @ResponseBody
    String getVacation(HttpServletResponse response) {
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("id", 111);
        map.put("title", "event1");
        map.put("start", "2012-4-15");
        map.put("url", "http://yahoo.com/");

        // Convert to JSON string.
        String json = new Gson().toJson(map);

        // Write JSON string.
        response.setContentType("application/json");
        response.setCharacterEncoding("UTF-8");

        return json;
    }
