关于controller接收json串的问题
        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:

  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!

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/octet-stream' not supported 格式不支持
application/octet-stream 是发送二进制数据时使用的
