JSON地圖 <String,ArrayList> 數據沒有在寧靜的球衣中轉換為bean對象

Question

使用String，Array和Map的JSON數據進行Ajax調用。 在轉換為澤西的DashboardChartData （Bean類）但無法獲取Map值后，我能夠獲取String和Array數據。 假設bean是DashboardChartData的對象，globalInFilters是DashboardChartData類的數據成員，並使setter / getter與bean相同，然后是bean.getGlobalInFilters（）; 得到null不是期望的值。

代碼是：

        function demo(){
           var dashbord = {
          "aoId": "M_AO_918",
          "viewBys": ["Brand", "Category", "State"],
          "viewIds": ["615228", "615128", "614847"],
          "dimensions": ["615228"],
          "aggregation": ["SUM", "SUM", "SUM", "SUM", "SUM", "SUM"],
          "meassures": ["Gross Sales", "Net Sales", "Discount Amt", "Discount%",  "Net Margin Amt", "Gross Margin Amt"],
          "meassureIds": ["616275", "616283", "616279", "616648", "616295", "616303"],
          "globalInFilters": {"615228": ["Lenovo", "Apple"]}
                        };

                        $("#query").html(JSON.stringify(dashbord));
                        $.ajax({
                            type: "POST",
                            contentType: "application/json; charSet=UTF-8",
                            dataType: "json",
                            data: JSON.stringify(dashbord),
                            url: "<%=request.getContextPath()%>/webresources/solrservice/test1",
                             success: function(data, textStatus, jqXHR){
                    alert('Bean created successfully');

                },
                error: function(jqXHR, textStatus, errorThrown){
                    alert('Bean error: ' + textStatus);
                }
                        });
            }    

我用上面的參數創建了DashboardChartData類，包括：

    private Map<String, List<String>> globalInFilters;

  public Map<String, List<String>> getGlobalInFilters() {
        return globalInFilters;
    }

    public void setGlobalInFilters(Map<String, List<String>> globalInFilters) {
        this.globalInFilters = globalInFilters;
    }


         @Path("/test1")
            @POST
            @Consumes(MediaType.APPLICATION_JSON)
            @Produces(MediaType.APPLICATION_JSON)
            public void setData1(DashboardChartDataBean bean) throws Exception {
                bean.getGlobalInFilters(); //getting null 
                 ProgenSolrDao daoObj = new ProgenSolrDao();

                try {
                    QueryResponse response = daoObj.executeSolrQuery("city",bean);
                } catch (Exception e) {

                }

            }

bean.getGlobalInFilters()獲取null ，除非所有其他值都正常。 請幫助我如何globalInFilters的值。

為什么在發送之前進行字符串化。 嘗試不使用stringify。
