网络错误：jqgrid 不接受 406

Question

我有一个 jqgrid 来填充来自后端的数据。直到控制器我有数据，但它没有在网格中呈现。启用 Fire 错误说 NetworkError: 406 Not Acceptable。 我的类路径和调度程序 aservlet 中有 jackson-core-asl-1.x.jar 和 jackson-mapper-asl-1.x.jar。 我还尝试根据解决方案之一更改标头为 headers="Accept=application/json"。我正在使用 SPring4。以下是我在控制器中的代码。

`

@RequestMapping(value = "/populateAddedDeviceGrid.html", headers="Accept=application/json", method = RequestMethod.POST)
    public @ResponseBody
    GridPojo populateAddedDeviceGrid(HttpServletRequest request, GridPojo gridPojo) {
        System.out.println("Enetering DeviceMasterController-->populateAddedDeviceGrid (POST)");

        List<DeviceMaster> deviceMasterList = new ArrayList<DeviceMaster>();

        try {
            deviceMasterList = deviceMasterService.getAllDeviceMaster();


            gridPojo.setGridData(deviceMasterList.toArray());
            gridPojo.setRows(deviceMasterList.size());
            gridPojo.setRecords(deviceMasterList.size());

        } catch (Exception e) {
            e.printStackTrace();
        }
        return gridPojo;
    }` 

Answer 1

我想在这里：

@RequestMapping(value = "/populateAddedDeviceGrid.html", headers="Accept=application/json", method = RequestMethod.POST)
//-------------------------------------------------------^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

这里应该使用headers 而不是produces，如下所示：

@RequestMapping(value = "/populateAddedDeviceGrid.html", produces={"application/json"} , method = RequestMethod.POST)
