  1. 我正在尝试一个使用xml-to-object-transformer>转换器在Mule3中将实际XML转换为Java对象的用例，而没有使用DW。我最终遇到了一个奇怪的问题，请检查是否有人可以帮助。
  3. 为了实现这个目标，
  5. 1. 使用XJC JAXB API生成了一个JAXB类。
  6. 2. 将该类设置为转换器中的别名类，以验证数据类型。
  7. 3. 使用上述别名进行xml-to-object-transformer转换。

  151. I am trying a usecase that the actual XML to be transformed as Java Object by using xml-to-object-transformer&gt; transformer in Mule3., no DW.  I ended up with a strange issue and pls chk if anyone can help.
  153. To do that,
  155.  1. Generated a JAXB class using XJC JAXB API  
  156.  2. Setting that class as alias class in the transformer to validate the data types
  157.  3. Do the xml-to-object-transformer with the above alias

  448. # 答案1
  449. **得分**: 0
  451. 似乎问题出在您正在使用&lt;mulexml:xml-to-object-transformer&gt;转换器，它不知道如何处理JAXB处理。您应该尝试使用[JAXB转换器][1]。
  453. 对于旧版本的Mule，有一个类似的先前答案：https://stackoverflow.com/a/20243878/721855
  455. [1]: https://docs.mulesoft.com/mule-runtime/3.9/jaxb-transformers
  457. <details>
  458. <summary>英文:</summary>
  460. It looks like the problem is that you are using the &lt;mulexml:xml-to-object-transformer&gt; transformer, which doesn&#39;t know how to handle JAXB processing. You should try instead the [JAXB transformers][1].
  462. There is a previous similar answer for an older version of Mule: https://stackoverflow.com/a/20243878/721855
  465.   [1]: https://docs.mulesoft.com/mule-runtime/3.9/jaxb-transformers
