Question

编辑：解决了。在提出这个问题时，Magento云连接器太旧了，无法使用Magento 1.7。

我正在尝试使用magento云连接器进行产品更新。我的xml看起来如下：

<magento:update-product config-ref="testConfig" doc:name="Update Product" productSku="#[header:OUTBOUND:ProductId]">
    <magento:catalog-product-entity name="#[header:outbound:Name]">
    </magento:catalog-product-entity>
    <magento:additional-attributes>
        <magento:additional-attribute key="isbn" value-ref="#[header:OUTBOUND:ISBN]" />
        <magento:additional-attribute key="subject" value-ref="#[header:OUTBOUND:Subject]" />    
    </magento:additional-attributes>        
</magento:update-product>

尝试进行更新始终会导致以下异常：

org.mule.api.transformer.TransformerException: Could not find a transformer to transform "SimpleDataType{type=java.lang.String, mimeType='*/*'}" to "SimpleDataType{type=com.magento.api.AssociativeEntity, mimeType='*/*'}".

正如评论中所指出的，我认为问题在于附加属性块，它试图将值从字符串转换为AssociativeEntity，但是失败了。我不太确定定义其他属性的正确语法是什么，因为api示例没有定义其他属性。

编辑：从value-ref变为value解决了变压器问题，但没有解决我遇到的根本问题。连接器使用太旧的wsdl，如Masse在下面指出的那样。

Answer 1

好像在这种情况下，value-ref不是正确使用的属性，而是值可以。然而，这并没有解决这种情况，因为magento-connector中使用的wsdl已经过时了。

当前的magento-connector wsdl符合magento 1.5标准。 wsdl是在2011年5月生成的，而magento通过添加single_data字段修改了2011年10月的wsdl。

因此，这背后的真正问题的答案是，实际上，它无法完成。 magento-connector插件需要更新，magento降级或启用WS-I合规模式，这有其自身的缺点

Mule Magento云连接器2.0，缺少变压器？
