java - ATG 创建组件并动态设置日志记录

Question

我正在使用 ATG 9.4 并尝试修改我们的促销引擎，以便我们可以设置每个促销的过滤器属性，而不是直接在全局 QualifierService 上设置。

基本上，我所做的就是为 QualifierService 上可用的每个过滤器标志添加属性到 Item Discount 存储库项目。然后我对 ItemDiscountCalculator 进行了子类化并重写了priceItems()。我从 pPricingModel 读取标志，构造一个新的 Qualifier 对象，并将其放入带有键 ItemDiscountCalculator.EXTRA_PARAM_QUALIFIERSERVICE 的 pExtraParameters 映射中。然后我调用 super.priceItems()

这对于我想要做的事情 100% 完美 - 但是，当我构造新的 Qualifier 时，我使用 setLoggingXXX 方法来反射(reflect)全局 QualifierService 上的任何级别，但是这些新对象没有记录.

我认为这与用 Nucleus 注册对象以及它使用的任何日志组件有关，但我无法找到注册它们所需的操作，或者至少允许 Qualifier 执行其操作自然伐木。

以下是相关代码行:

@Override
@SuppressWarnings("unchecked")
public void priceItems(List pPriceQuotes, List pItems, RepositoryItem pPricingModel, Locale pLocale, RepositoryItem pProfile, Order pOrder, Map pExtraParameters) throws PricingException {
    if (isLoggingTrace())
        logTrace("Entry - CustomItemDiscountCalculator.priceItems()");

    Qualifier qualifierService = getQualifierService(pPricingModel);

    if (pExtraParameters == null) {
        pExtraParameters = new HashMap();
    }

    pExtraParameters.put(ItemDiscountCalculator.EXTRA_PARAM_QUALIFIERSERVICE, qualifierService);

    super.priceItems(pPriceQuotes, pItems, pPricingModel, pLocale, pProfile, pOrder, pExtraParameters);

    if (isLoggingTrace())
        logTrace("Exit - CustomItemDiscountCalculator.priceItems()");
}

private Qualifier getQualifierService(RepositoryItem pPricingModel) {
    if (isLoggingTrace())
        logTrace("Entry - CustomItemDiscountCalculator.getQualifierService()");

    Qualifier qualifierService = new Qualifier();

    /* Get global component at /atg/commerce/pricing/QualifierService */
    Qualifier defaultQualifierService = getQualifierService();

    /* Shallow clone the global QualifierService component */
    qualifierService.setPMDLCache(defaultQualifierService.getPMDLCache());
    qualifierService.setClosenessQualifierItemDescriptorName(defaultQualifierService.getClosenessQualifierItemDescriptorName());
    qualifierService.setExactlyPromotionLoopThrough(defaultQualifierService.isExactlyPromotionLoopThrough());
    qualifierService.setLoggingDebug(defaultQualifierService.isLoggingDebug());
    qualifierService.setLoggingError(defaultQualifierService.isLoggingError());
    qualifierService.setLoggingInfo(defaultQualifierService.isLoggingInfo());
    qualifierService.setLoggingTrace(defaultQualifierService.isLoggingTrace());
    qualifierService.setLoggingWarning(defaultQualifierService.isLoggingWarning());
    qualifierService.setNucleus(defaultQualifierService.getNucleus());
    qualifierService.setPricingModelProperties(defaultQualifierService.getPricingModelProperties());
    qualifierService.setPricingModelRepository(defaultQualifierService.getPricingModelRepository());
    qualifierService.setServiceInfo(defaultQualifierService.getServiceInfo());

    /* Set any promotion specific qualifier properties */
    Boolean curFilterValue;
    if (isLoggingDebug()) {
        logDebug("Setting qualifier properties for promo: " + pPricingModel);
    }

    curFilterValue = (Boolean) pPricingModel.getPropertyValue("filterForQualifierDiscountedByAnyDiscountId");
    qualifierService.setFilterForQualifierDiscountedByAnyDiscountId(curFilterValue);

    // ... copy the rest of the QualifierService filters

    if (isLoggingTrace())
        logTrace("Exit - CustomItemDiscountCalculator.getQualifierService()");
    return qualifierService;
}

Answer 1

LogListener[] logListeners = defaultQualifierService.getLogListeners();
for (LogListener[] logListener : logListeners) {
    qualifierService.addLogListener(logListener);
}
