java - 访问地址时出现服务器错误，但没有堆栈跟踪

问题描述

我有一个带有单个映射的 hybris 网站。每次我尝试访问特定的网址时：

在此处输入图像描述

有没有办法调试这样的错误？

这是页面的控制器：

@Controller
@RequestMapping(value = "/cart")
public class CartPageController extends AbstractPageController
{
    private static final String CART_CMS_PAGE = "cartPage";
    private static final Integer DEFAULT_COOKIE_EXPIRY_AGE = 5184000;
    private static final String DEFAULT_CART_IDENTIFIER_COOKIE_NAME = "cart.identifier.cookie.name";
    private static final Logger LOG = Logger.getLogger(CartPageController.class);


    @Resource(name = "cartFacade")
    private CartFacade cartFacade;

    @Resource(name = "userService")
    private UserService userService;

    @Resource(name = "baseStoreService")
    private BaseStoreService baseStoreService;

    @Resource(name = "catalogVersionService")
    private CatalogVersionService catalogVersionService;

    @RequestMapping(method = RequestMethod.GET)
    public String showCart(HttpServletRequest request, HttpServletResponse response, final Model model)
            throws CMSItemNotFoundException
    {

        CartData cartData = cartFacade.getSessionCartWithEntryOrdering(true);

        final String cartCookieIdentifier = getCartCookieIdentifier();

        if (!cartFacade.hasEntries())
        {
            final String cartId = getCookieValue(request, cartCookieIdentifier);

            final Optional<CartData> cartDataOptional = cartFacade.getCartsForCurrentUser().stream()
                    .filter(c -> c.getCode().equals(cartId)).findFirst();

            if (cartDataOptional.isPresent())
            {
                cartData = cartDataOptional.get();
            }
        }

        setCookieValue(response, cartCookieIdentifier, cartData.getCode());
        model.addAttribute("cart", cartData);

        setupPageModel(model);

        String model1 = getViewForPage(model);

        return model1;

    }

    protected void setupPageModel(Model model) throws CMSItemNotFoundException
    {
        storeCmsPageInModel(model, getContentPageForLabelOrId(CART_CMS_PAGE));
        setUpMetaDataForContentPage(model, getContentPageForLabelOrId(CART_CMS_PAGE));
    }

    protected String getCookieValue(final HttpServletRequest request, final String cookieName)
    {
        return Arrays.stream(request.getCookies())
                .filter(c -> c.getName().equals(cookieName))
                .findFirst()
                .map(Cookie::getValue)
                .orElse(null);
    }

    protected void setCookieValue(final HttpServletResponse response, final String cookieName, final String cookieValue)
    {
        final Cookie cookie = new Cookie(cookieName, cookieValue);
        cookie.setMaxAge(DEFAULT_COOKIE_EXPIRY_AGE);

        response.addCookie(cookie);
    }

    protected String getCartCookieIdentifier()
    {
        final String baseStoreId = getCurrentBaseStoreId();
        final String catalogId = getCurrentProductCatalogId();

        if (StringUtils.isNotEmpty(baseStoreId) && StringUtils.isNotEmpty(catalogId))
        {
            return baseStoreId + "-" + catalogId;
        }

        return DEFAULT_CART_IDENTIFIER_COOKIE_NAME;
    }

    protected String getCurrentBaseStoreId()
    {
        final BaseStoreModel baseStore = baseStoreService.getCurrentBaseStore();
        return baseStore == null ? StringUtils.EMPTY : baseStore.getUid();
    }

    protected String getCurrentProductCatalogId()
    {
        for (final CatalogVersionModel catalogVersionModel : catalogVersionService.getSessionCatalogVersions())
        {
            if (!((catalogVersionModel.getCatalog() instanceof ContentCatalogModel) || (catalogVersionModel
                    .getCatalog() instanceof ClassificationSystemModel)))
            {
                return catalogVersionModel.getCatalog().getId();
            }
        }
        return StringUtils.EMPTY;
    }
}

页面的内容jsp并不那么重要，因为它可能是空的，并且这种行为仍然会发生。我不知道这到底是什么原因。是否有任何有效的方法来调试此类问题？

解决方案

这是创建 B2B 站点时的常见错误。一种解决方法是打开 /smartedit 并从那里登录到您的站点。Hybris 将创建一个适当的会话，您应该能够打开该站点。

可能的长期解决方案：如果您正在创建 B2B 站点，请检查您的 Storefront 扩展中的 spring-filter-config.xml 并检查此部分。它应该如下所示：

    <alias name="b2cAcceleratorSiteChannels" alias="acceleratorSiteChannels"/>
    <util:set id="b2cAcceleratorSiteChannels" value-type="de.hybris.platform.commerceservices.enums.SiteChannel">
        <ref bean="SiteChannel.B2C"/>
        <ref bean="SiteChannel.B2B"/>
    </util:set>

如果一切正常，您可以删除 SiteChannel.B2C
