我是M子的新手。
我尝试使用SOAP创建一个简单的登录流程，该流程将返回XML响应。我的方法是使用XML发送数据，然后将登录数据保存在转换代码中，保存数据后，返回的数据将生成到xml响应中。但是我出现了错误:“有两个与输入完全匹配的变压器”。我不明白为什么会这样。
请帮我解决这个问题。
这是我的流程代码:
<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0"
port="8081" doc:name="HTTP Listener Configuration"/>
<cxf:configuration name="CXF_Configuration" enableMuleSoapHeaders="true" initializeStaticBusInstance="true" doc:name="CXF Configuration"/>
<mulexml:jaxb-context name="myJaxb" packageNames="com.test.service" doc:name="JAXB Context"/>
<flow name="LoginFlow" initialState="started">
<http:listener config-ref="HTTP_Listener_Configuration" path="/Login" doc:name="HTTP"/>
<cxf:proxy-service configuration-ref="CXF_Configuration" doc:name="CXF" namespace="http://www.test.co.id/SOA/service/1.0" payload="body" port="LoginPort" service="LoginService" wsdlLocation="service/login-test.wsdl"/>
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
<mulexml:dom-to-xml-transformer returnClass="java.lang.String" doc:name="DOM to XML"/>
<logger message="#[payload]" level="INFO" doc:name="Logger"/>

<mulexml:jaxb-object-to-xml-transformer jaxbContext-ref="myJaxb" doc:name="JAXB Object to XML"/>
<mulexml:xml-to-dom-transformer doc:name="XML to DOM"/>
</flow>

1. There are two transformers that are an exact match for input: "class org.mule.module.cxf.CxfInboundMessageProcessor$1", output: "class [B". Transformers are: "XmlToByteArray(class org.mule.module.xml.transformer.XmlToDomDocument)" and "_ObjectToByteArray(class org.mule.transformer.simple.ObjectToByteArray)" (org.mule.api.registry.ResolverException)

感谢您的回答。 :)
最佳答案
我怀疑这是由于最后的DOM-to-XML组件所致。
您可以删除它并尝试一下吗，因为在DOM-to-XML之前有Jaxb-to-xml组件
