关于controller接收json串的问题

Question

        js:
        function aaa(){     
         var rows = $('#dg').datagrid('getSelections');
        location.href="exportbus.do?swBus="+JSON.stringify(rows);
        }
        java后台：
@RequestMapping("/exportbus.do")

@ResponseBody
public void exportbus(@RequestBody SwBus[] swBus,HttpServletRequest request,HttpServletResponse response)throws Exception{
try {
System.out.println("===========");
HSSFWorkbook workbook=new HSSFWorkbook();
String titles[] = {"企业名称","组织机构代码"};
控制台报错：

jsp页面直接415

1. http 415错误是请求错误，首先你检查一下你的代码有问题没，比如大小写！！以及exportbus.do存在么？去swBusController里好好看一下
2. 其次，断点测试各个数据！！看看数据传输的对不对！一步一步调！程序断点或者用浏览器调！
3. 检查exportbus.do里返回的值！
