Spring3和jqgrid，我试图从控制器将数据加载到选择选项中，但无法填充

我正在使用Spring3和jqgrid，除了从控制器将数据加载到select选项之外，一切都正常。我尝试将数据加载到jsion数组对象并发送到jsp页面，但我无法使用

(editoptions: {dataUrl:"location/role.do")

请查看我的代码并帮助我

我的控制器类是

@Controller
@RequestMapping("/location")
public class AddCenterLocation {

    @Autowired
    private RecoupService recoupService;

    @RequestMapping(method = RequestMethod.GET)
    public @ResponseBody
    CustomCenterLocationResponse getAll() {
        List<? extends CenterLocation> users = recoupService.getCenter();
        response.setRows(users);
        response.setRecords(String.valueOf(users.size()));
        response.setPage("1");
        response.setTotal("10");
        return response;
    }

    @RequestMapping(value = "/role", method = RequestMethod.GET)
    public @ResponseBody
    CustomGenericResponse role(HttpServletRequest request, HttpServletResponse response) {
        JSONObject jsonArray = new JSONObject();
        try {
            List<CenterLocation> users = recoupService.getCenter();
            for (CenterLocation harbour : users) {
                jsonArray.put(harbour.getCenterId(), harbour.getCenterAddress());
            }
            response.getWriter().write(jsonArray.toString());
        } catch (Exception exception) {
            System.out.println("error is " + exception);
        }
        return null;

    }

@控制器
@请求映射（“/location”）
公共类AddCenterLocation{
@自动连线
私有资源服务资源服务；
@RequestMapping（method=RequestMethod.GET）
公共@ResponseBody
CustomCenterLocationResponse getAll（）{
List第一个jackson lib被导入lib文件夹，用于将json数据发送到jsp页面。
然后
创建两个pojo类这仅用于演示，您可以根据需要进行更改

公共类位置{

列表角色

 //setter getter

}

公共阶级角色
{

//塞特吸气剂

}

这是控制器请求

@Controller
@RequestMapping("/location")
public class AddCenterLocation {

    @Autowired
    private RecoupService recoupService;

    @RequestMapping(method = RequestMethod.GET)
    public @ResponseBody
    CustomCenterLocationResponse getAll() {
        List<? extends CenterLocation> users = recoupService.getCenter();
        response.setRows(users);
        response.setRecords(String.valueOf(users.size()));
        response.setPage("1");
        response.setTotal("10");
        return response;
    }

    @RequestMapping(value = "/role", method = RequestMethod.GET)
    public @ResponseBody
    CustomGenericResponse role(HttpServletRequest request, HttpServletResponse response) {
        JSONObject jsonArray = new JSONObject();
        try {
            List<CenterLocation> users = recoupService.getCenter();
            for (CenterLocation harbour : users) {
                jsonArray.put(harbour.getCenterId(), harbour.getCenterAddress());
            }
            response.getWriter().write(jsonArray.toString());
        } catch (Exception exception) {
            System.out.println("error is " + exception);
        }
        return null;

    }

@RequestMapping（value=“/role”，method=RequestMethod.GET）

public@ResponseBody
位置角色（HttpServletResponse）{
System.out.println（“名称”）；
地点商店=新地点（）；
列表=新的ArrayList（）；
角色=新角色（）；
角色设置ID（“abc”）；
角色设置名称（“abc”）；
列表。添加（角色）；
Role role1=新角色（）；
角色1.setId（“abc1”）；
角色1.集合名（“abc1”）；
列表。添加（角色1）；
shop.setRole（列表）；
退货店；
}

修改jqgrid的选择部分

{ name: 'name', index: 'name', editable: true, edittype: "select",
 editoptions: {dataUrl:"location/role.do", 
buildSelect: function (role) 
{ 
var data = jQuery.parseJSON(role); 
var s = '<select>'; 
for (var i = 0; i < data.role.length; i++) {
 s += '<option value="' + data.role[i].id + '">' + data.role[i].name + '</option>'; 
} 
return s + "</select>"; 
} 
} 
}

{name:'name'，index:'name'，可编辑：true，edittype:“select”，
editoptions:{dataUrl:“位置/角色.do”，
buildSelect:功能（角色）
{ 
var data=jQuery.parseJSON（角色）；
var s=''；
对于（变量i=0；i

一切都会好起来的

{ name: 'name', index: 'name', editable: true, edittype: "select",
 editoptions: {dataUrl:"location/role.do", 
buildSelect: function (role) 
{ 
var data = jQuery.parseJSON(role); 
var s = '<select>'; 
for (var i = 0; i < data.role.length; i++) {
 s += '<option value="' + data.role[i].id + '">' + data.role[i].name + '</option>'; 
} 
return s + "</select>"; 
} 
} 
}
