Web services 使用mule使用一个简单的web服务

我试图使用Mule+apachecxf使用公共服务。这项服务可在

这是一个非常简单的服务，它执行基本的算术运算。我试图在这里调用“添加”操作。我的mule配置如下所示

<flow name="calculator" doc:name="calculator">

<stdio:inbound-endpoint system="IN" doc:name="STDIO"/>
<custom-transformer class="com.calculator.transformer.CalculatorClient" doc:name="Java"/>

<outbound-endpoint address="http://localhost:28081/service/Calculator?WSDL" exchange-pattern="request-response" doc:name="HTTP">

  <cxf:jaxws-client clientClass="com.calculator.wsdl.Calculator" enableMuleSoapHeaders="true" port="CalculatorHttpPost" wsdlLocation="classpath:/wsdl/Calculator.wsdl" operation="Add">
      <cxf:inInterceptors>
    <spring:bean class="org.apache.cxf.interceptor.LoggingInInterceptor" />
    </cxf:inInterceptors>
    <cxf:outInterceptors>
      <spring:bean class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
    </cxf:outInterceptors>
  </cxf:jaxws-client>

</outbound-endpoint>

 <transformer ref="CalculatorResponse" doc:name="Transformer Reference"/>

 <mulexml:jaxb-object-to-xml-transformer name="CalculatortoXML" jaxbContext-ref="myJaxbCal" />



<stdio:outbound-endpoint system="OUT" doc:name="STDIO"/>


</flow>

一旦我启动mule，我就会收到错误。不确定我做错了什么

您提到了

http://localhost:28081/service/Calculator?WSDL

作为您的地址，我想应该是

http://localhost:28081/service/Calculator

这篇文章帮助我解决了这个问题

通过使用建议的JAXB绑定，CXF将生成包装器对象。

是的，我得到的错误是参数数量错误。我不确定我是否正确执行此操作替换java.lang.IllegalArgumentException后面临的名称问题：参数数量错误
