老师, 在修改了 point 相关的代码之后. 在访问 http://localhost:8080/O2O/shopadmin/productmanagement 无法访问, chrome 控制台也没有显示错误, 日志中也没有错误.

@Controller
@RequestMapping(value = "shopadmin", method = RequestMethod.GET)
public class ShopAdminController {
    @RequestMapping(value = "/shopoperation")
    public String shopOperation() {
        return "shop/shopoperation";
    }
    @RequestMapping(value = "/shoplist")
    public String shopList() {
        return "shop/shoplist";
    }

    @RequestMapping(value = "/shopmanagement")
    public String shopManagement() {
        return "shop/shopmanagement";
    }
    @RequestMapping(value = "/productcategorymanagement", method = RequestMethod.GET)
    private String productCategoryManage() {
        return "shop/productcategorymanagement";
    }


    @RequestMapping(value = "/productoperation")
    public String productOperation() {
        // 转发至商品添加/编辑页面
        return "shop/productoperation";
    }

    @RequestMapping(value = "/productmanagement")
    public String productManagement() {
        return "shop/productmanagement";
    }
}

上面这个 controller 里面的 shopadmin/shopoperation、shopadmin/shopmanagement、shopadmin/shoplist 都是可以访问的, 但是 shopadmin/productoperation、shopadmin/productmangement、shopadmin/productcategorymanagement 无法访问, 我登陆了账号, 是拦截器的原因吗? 麻烦老师看看. 没有看到任何的报错.
