jqgrid自带的导航怎么向后台传递json类型的数据

[liuying8008]

我在使用jqgrid自带的导航时，向后台传的数据为“departId=&departName=&=&planDate=&departAmount=&oper=add&id=_empty”这种类型，后台是springmvc，用@RequestBody无法接收这种类型的数据，如何才能转换成json的呢

$("#jqGrid").jqGrid({
        url: '../sys/depart/queryDepartList?projectId=null',
        datatype: "json",
        colModel: [			
			{ label: '部门编号', name: 'departId', width: 40 , editable: true},
			{ label: '部门名称', name: 'departName', width: 60 , editable: true},
			{ label: '责任人', name: 'departChargeMan', width: 60 , editable: true , edittype:'select' , editoptions:{}},
			{ label: '预估工期', name: 'planDate', width: 60 , editable: true},
			{ label: '预估金额', name: 'departAmount', width: 60 , editable: true, formatter: 'number'}
			/*{ label: '创建时间', name: 'createTime', width: 50},
			{ label: '创建人', name: 'createUser', width: 100}*/
        ],
		viewrecords: true,
        height: 400,
        width:400,
        rowNum: 10,
        editurl:'../sys/test',
		rowList : [20,30,50],
		footerrow : true,
		userDataOnFooter : true,
		altRows : true,
		//pgbuttons: false,//上下按钮 
		//pginput:false,//输入框
        sortorder : "desc",
        caption : "部门列表",
        pager: "#jqGridPager",
        jsonReader : {
            root: "page.list",
            page: "page.currPage",
            total: "page.totalPage",
            records: "page.totalCount"
        },
        prmNames : {
            page:"page", 
            rows:"limit", 
            order: "order"
        },
        gridComplete : function(){
        	var rowNum=parseInt($(this).getGridParam("records"),10);
        	if(rowNum>0){    
        	         $(".ui-jqgrid-sdiv").show();
        	 var count=$(this).getCol("departAmount",false,"sum"); 
        	 var planDate = $(this).getCol("planDate",false,"sum"); 
        	$(this).footerData("set",{"departId":"合计","planDate":planDate,"departAmount":count}); //将合计值显示出来
        	        }else{
        	                 $(".ui-jqgrid-sdiv").hide();
        	}
        },
        onSelectRow : function(id){
        	var id = $("#jqGrid").jqGrid('getGridParam','selrow');
        	var rowData = $("#jqGrid").jqGrid("getRowData",id);
        	departId = rowData.departId;
              
              jQuery("#jqGrid1").jqGrid('setGridParam',{url:"../sys/depart/queryListByDepartId?departId="+departId+"&projectId="+vm.pSelected,page:1});
              jQuery("#jqGrid1").jqGrid('setCaption',"工作类别").trigger('reloadGrid');
         }
    });

var navParams = {
            edit:true,
            add:true,
            del:true,
            view:false,
            search:false,
            addfunc : function(){
                var addParams = {
                        url : "../sys/depart/save?projectId="+vm.pSelected,
                        /*datatype: "json"*/
                };
                $("#jqGrid").jqGrid("editGridRow","new",addParams);
            },
            editfunc : function(rowId){
                var editParams = {
                        url:'../sys/depart/update?id='+rowId,
                        closeAfterEdit : true,
                        bSubmit: "Submit",
                        datatype: "json"
                };
                $("#jqGrid").jqGrid("editGridRow",rowId,editParams);
            },
            delfunc : function(rowId){
            	var rowData = $("#jqGrid").jqGrid("getRowData",rowId);
            	var projectId = vm.pSelected;
            	departId = rowData.departId;
            	console.log(projectId+"----"+departId);
            	var delParams = {                 
                        url:'../sys/depart/delete?id='+rowId+"&projectId="+projectId+"&departId="+departId,
                        closeAfterEdit : true
                };
            	$("#jqGrid").jqGrid("delGridRow",rowId,delParams);
            }
    };
    jQuery("#jqGrid").jqGrid('navGrid',"#jqGridPager",navParams);
