如何覆盖BroadleafCategoryController [宽叶商务]

Question

当我尝试覆盖BroadleafCategoryController handleRequest方法时，对我来说一切都很好。但是，当我尝试使用Device参数调用如下所示的相同方法来标识用户设备时

在我的Java类CategoryController.java中

@Controller("blCategoryController")
        public class CategoryController extends BroadleafCategoryController {

            private static final Logger logger = LoggerFactory.getLogger(CategoryController.class);

            @RequestMapping("/")
            public ModelAndView handleRequest(Device currentDevice, HttpServletRequest request, HttpServletResponse response) throws Exception {

        return super.handleRequest(request, response);

            }

        }

然后，当它进入超方法(handleRequest)时，我将Category对象的值作为NULL。

Category category = (Category) request.getAttribute(CategoryHandlerMapping.CURRENT_CATEGORY_ATTRIBUTE_NAME);
The above value should have been set through CategoryHandlerMapping

        public class CategoryHandlerMapping extends BLCAbstractHandlerMapping {
                    public static final String CURRENT_CATEGORY_ATTRIBUTE_NAME = "category";

            protected String defaultTemplateName = "catalog/category";

            private String controllerName = "blCategoryController";


            @Override
            protected Object getHandlerInternal(HttpServletRequest request) throws Exception {
                Category category = null;
                if (allowCategoryResolutionUsingIdParam()) {
                    category = findCategoryUsingIdParam(request);
                }

                if (category == null) {
                    category = findCategoryUsingUrl(request);
                }

                if (category != null) {
                    request.setAttribute(CURRENT_CATEGORY_ATTRIBUTE_NAME, category);
                    return controllerName;
                }

                return null;
            }

在带有@Configuration注释的类中配置了CategoryHandlerMapping (由Broadleaf Commerce提供)，并在带有@Bean注释的方法中创建了对象。

@Bean
public HandlerMapping categoryHandlerMapping() {
    CategoryHandlerMapping mapping = new CategoryHandlerMapping();
    mapping.setOrder(5);
    return mapping;
}

注：-所有与设备相关的配置(Spring-Mobile)都很好，如果我遗漏了任何像applicationContext.xml这样的xml配置，请让我知道？提前感谢！

category控制器稍有不同，并且不是由RequestMappingHandlerMapping解析的(它解析您的@RequestMapping片段)。相反，正如您所提到的，调用CategoryController的handleRequest()方法的唯一方式是通过CategoryHandlerMapping。这就是处理类别URL的部分。

看起来您只是在尝试找出类别页面上的当前Device。Spring Mobile有一个简单的DeviceUtils.getCurrentDevice(request)就能做到这一点的工具。所以：

从handleRequest()

• Rewrite

1. 中删除@RequestMapping，如下所示：

@Controller("blCategoryController")公有类CategoryController扩展了BroadleafCategoryController {私有静态最终记录器记录器=BroadleafCategoryController公有ModelAndView handleRequest(HttpServletRequest请求，HttpServletResponse响应)抛出异常{ Device currentDevice = DeviceUtils.getCurrentDevice(request)；return super.handleRequest(request，response)；} }
