在Java中使用Highcharts+Ajax+Json生成动态饼图

1.由于HighCharts运行于jQuery，所以需要引入jQuery。 jquery-1.8.3.min 
HighCharts核心js文件 highcharts.js 
导出功能需要引入的js exporting.js 
完整文件 Highcharts-4.2.5 
2.在jsp页面引入如上文件

<script type="text/javascript">
        var chart;
$(function () {

    $(document).ready(function() {
        chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container',
                plotBackgroundColor: null,
                plotBorderWidth: null,
                plotShadow: false
            },title: {
                text: '教师绩效分析图'
            },
            tooltip: {
                pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
            },
            plotOptions: {
                pie: {
                    allowPointSelect: true,
                    cursor: 'pointer',
                    dataLabels: {
                        enabled: true,
                        color: '#000000',
                        connectorColor: '#000000',
                        format: '<b>{point.name}</b>: {point.percentage:.1f} %'
                    },
                    showInLegend: true
                }
            },
            series: [{
                type: 'pie',
                name: '所占比例',
            }]
        });
    });
      //调用查询，加载数据
      chaxun();
});
    function chaxun(){
        var arr = [];
        var param = $('#groupS').val();
           if($('#departmentS').val()!="全部"){
               param += "&department="+$('#departmentS').val();
           }
           if($('#typeS').val()!="全部"){
               param += "&type="+$('#typeS').val();
           }
        $.ajax({
            type:'get',
            url:'/SX2/WorkloadAnalysis/getData?group='+param,//请求数据的地址
            beforeSend:function(XMLHttpRequest){ 
                   $('#loading').show();
                   $('#contentDIV').hide();
                   $('#loading').html("<img src='<%=path%>/image/loading.gif' />"); 
               }, 
             success: function(data){
                $('#contentDIV').show();
                $('#loading').hide();

                $(data.data).each(function(index,item){
                    arr.push([item.name,item.num]);
                });
               chart.series[0].setData(arr);//数据填充到highcharts上面 
            },
            error:function(e){
                alert("不好意思，请要访问的图标跑到火星去了。。。。");
            } 
        });
    };
        </script>

3.Controller代码

 @RequestMapping("getData")
    @ResponseBody
    public Map<String,Object> getData(Integer department,Integer group,String type){
        Map<String,Object> map = new HashMap<String,Object>();
        map.put("title", "教师绩效考核结果分析");
        HashMap<String,Object> param = new HashMap<>();
        param.put("department", department);
        param.put("group", group);
        param.put("type", type);
        List<Map<String,Object>> list = ws.selectWorkloadAnalysis(param);
        map.put("data",list);
        return map;
    }

返回数据样例

{"title":"教师绩效考核结果分析","data":[{"num":0,"name":"0-20分"},{"num":1,"name":"21-40分"},{"num":0,"name":"41-60分"},{"num":0,"name":"61-80分"},{"num":0,"name":"81-100分"}]}

4.请求Controller，网页显示如下：
