如何在 Spring 中解决 FatalBeanException？

Question

我得到以下异常：

org.springframework.beans.FatalBeanException: 无法正确创建上下文 hybris 全局上下文工厂，原因是在类路径资源 [config/cmsfacades-cmsitems-spring .xml]: bean 初始化失败；

在类路径资源 [ordermanagementfacades-spring.xml] 中定义名称为“ordermanagementOrderConverter”的 bean 创建时出错：使用键 [0] 设置 bean 属性“populators”时无法解析对 bean 'ordermanagementOrderPopulator' 的引用；

在类路径资源 [ordermanagementfacades-spring.xml] 中创建名称为“ordermanagementOrderPopulator”的 bean 时出错：在设置 bean 属性“orderEntryConverter”时无法解析对 bean“ordermanagementOrderEntryConverter”的引用；

在类路径资源 [ordermanagementfacades-spring.xml] 中创建名称为“ordermanagementOrderEntryConverter”的 bean 时出错：使用键 [0] 设置 bean 属性“populators”时无法解析对 bean 'ordermanagementOrderEntryPopulator' 的引用；

在类路径资源 [warehousingfacades-spring.xml] 中创建名称为“warehousingOrderEntryPopulator”的 bean 时出错：在设置 bean 属性“productConverter”时无法解析对 bean“ordermanagementProductConverter”的引用；

在类路径资源 [ordermanagementfacades-spring.xml] 中创建名称为“ordermanagementProductConverter”的 bean 时出错：使用键 [0] 设置 bean 属性“populators”时无法解析对 bean 'ordermanagementProductPopulator' 的引用；

在类路径资源 [ordermanagementfacades-spring.xml] 中定义名称为“ordermanagementProductPopulator”的 bean 创建错误：设置属性值时出错；

bean 类 [de.hybris.platform.ordermanagementfacades.product.converters.populator.OrdermanagementProductBasicPopulator] 的无效属性“designerConverter”：Bean 属性“designerConverter”不可写或具有无效的 setter 方法。 setter的参数类型和getter的返回类型是否匹配？

这是我的 bean 注册：

   <alias name="defaultCustomProductBasicPopulator" alias="productBasicPopulator"/>
    <bean id="defaultCustomProductBasicPopulator" parent="defaultProductBasicPopulator"
    class="de.hybris.NagAcc.facades.product.converters.populator.CustomProductBasicPopulator">
        <property name="designerConverter" ref="designerConverter" />
    </bean>

这是课程：

public class CustomProductBasicPopulator<SOURCE extends ProductModel, TARGET extends ProductData> extends ProductBasicPopulator<SOURCE,TARGET> {

    private Converter<DesignerModel,DesignerData> designerConverter;

    public Converter<DesignerModel, DesignerData> getDesignerConverter() {
        return designerConverter;
    }

    public void setDesignerConverter(Converter<DesignerModel, DesignerData> designerConverter) {
        this.designerConverter = designerConverter;
    }

    @Override
    public void populate(SOURCE productModel, TARGET productData) throws ConversionException {
        super.populate(productModel, productData);
        if (productModel.getDesigner() != null)
        {
            DesignerData designerData = getDesignerConverter().convert(productModel.getDesigner());
            productData.setDesigner(designerData);
        }
    }

这是父 bean 定义：

<alias name="defaultProductBasicPopulator" alias="productBasicPopulator"/>
    <bean id="defaultProductBasicPopulator" parent="baseProductPopulator"
          class="de.hybris.platform.commercefacades.product.converters.populator.ProductBasicPopulator">
        <property name="productConfigurableChecker" ref="productConfigurableChecker"/>
    </bean>

完整的堆栈跟踪：

据我所知，所有的 getter 和 setter 都很好，我无法解决这个错误。请帮忙。

Answer 1

我无法访问 hybris 资源来查看（感谢上帝！），但我认为值得查看 Javadoc of OrdermanagementProductBasicPopulator：

public void populate​(ProductModel productModel, ProductData productData) 从接口复制的描述：Populator 使用源实例中的值填充目标实例。 覆盖： 在 ProductBasicPopulator 类中填充

所以我猜，class OrdermanagementProductBasicPopulator extends ProductBasicPopulator 但OrdermanagementProductBasicPopulator 的bean 定义 有你的productBasicPopulator 作为父级，这意味着spring 试图注入您的 bean 定义的属性，它不是 OrdermanagementProductBasicPopulator 的继承链中的属性。

如前所述，这只是一个猜测，因为我没有看到来源...... 如果我的猜测是正确的，这取决于您的要求如何摆脱这个问题。您可以给您的 bean 一个新别名并在必要时修改填充器列表，或者您相应地覆盖 OrdermanagementProductBasicPopulator 的 bean 别名。

如果这不是问题，请发布OrdermanagementProductBasicPopulator的bean定义。
