如何解决 Spring 中的 FatalBeanException？

Question

我得到以下异常：

org.springframework.beans.FatalBeanException: Context hybris Global Context Factory couldn't be created correctly due to, Error creating bean with name 'modifyPopulatorList$child#0' defined in class path resource [config/cmsfacades-cmsitems-spring.xml]: Initialization of bean failed;

Error creating bean with name 'ordermanagementProductPopulator' defined in class path resource [ordermanagementfacades-spring.xml]: Error setting property values;

Invalid property 'designerConverter' of bean class [de.hybris.platform.ordermanagementfacades.product.converters.populator.OrdermanagementProductBasicPopulator]: Bean property 'designerConverter' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

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 class :

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>

根据我的说法，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) Description copied from interface: Populator Populate the target instance with values from the source instance. Overrides: populate in class ProductBasicPopulator

所以我猜，class OrdermanagementProductBasicPopulator extends ProductBasicPopulator 但是 OrdermanagementProductBasicPopulator 的 bean 定义将您的 productBasicPopulator 作为父级，这意味着 spring 尝试注入您的 bean 定义的属性，这不是 [=11 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 bean 一个新别名并在必要时修改填充器列表，或者相应地覆盖 OrdermanagementProductBasicPopulator 的 bean 别名。

如果那不是问题，请 post OrdermanagementProductBasicPopulator 的 bean 定义。
