Java Mule TransformerException:返回类型无效；为变压器“JAXBMarshallertTransformer”指定了[B”类；

我正在使用Mule CXF组件从localhost调用web服务。被调用的web服务返回SoapResult类型的对象，但Mule在转换它时，检测返回类型为“[B”。最后，选择了JAXBMarshallerTransformer，转换失败，此堆栈：

org.mule.api.transformer.TransformerException: An invalid return type "class [B" was specified for transformer "JAXBMarshallerTransformer"
at org.mule.module.xml.transformer.jaxb.JAXBMarshallerTransformer.doTransform(JAXBMarshallerTransformer.java:119)
at org.mule.transformer.AbstractTransformer.transform(AbstractTransformer.java:420)
at org.mule.DefaultMuleMessage.getPayload(DefaultMuleMessage.java:377)
+ 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

我找到了答案：调用web服务后，只需在响应标签中添加transformer，如：

 <response>
        <data-mapper:transform config-ref="Pojo_To_XML" doc:name="Pojo To XML"/>
        <logger message="#[payload]" level="INFO" doc:name="Logger"/>
 </response>

datamapper transformer仅在企业版中可用，您也可以使用

将对象转换为XML。

是的，您是对的。我提到过任何转换器都可以使用，但只能在示例代码中使用data mapper。您需要使用响应范围吗？
