web-services - 如何使用 cxf 组件使用 Apache camel 调用第三方 Web 服务

标签 web-services apache wsdl apache-camel

我浏览了 Apache camel 网站上的示例和camel in action，两者都非常关注暴露网络服务。我在网上找到的唯一示例不起作用。

我正在尝试访问第三方网络服务 wsdl - http://www.webservicex.net/CurrencyConvertor.asmx?WSDL

此服务具有计算货币汇率的操作/方法。操作名称是“ConversionRate”。

我定义了这样的路线 -

      <?xml version="1.0" encoding="UTF-8"?>
<!-- Configures the Camel Context-->

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/spring"
       xmlns:cxf="http://camel.apache.org/schema/cxf"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

  <camelContext xmlns="http://camel.apache.org/schema/spring">

    <route>
        <description>here is a sample which processes the input files
         (leaving them in place - see the 'noop' flag)
         then performs content based routing on the message using XPath</description>
        <from uri="file:src/data/order?noop=true"/>
        <log message="${body}"/>

        <to uri="cxf://http://www.webservicex.net/CurrencyConvertor.asmx?wsdlURL=http://www.webservicex.net/CurrencyConvertor.asmx?wsdl&amp;serviceName=CurrencyConvertor&amp;portName=http://www.webserviceX.NET/tns:CurrencyConvertorSoap&amp;dataFormat=MESSAGE"/>
        <log message="${body}"/>
    </route>
</camelContext>

</beans>

我已将示例有效负载 xml 定义为 -
<order>
        <Id>1</Id>
        <Price>10.00</Price>
        <Quantity>2</Quantity>
</order>

运行此示例时出现此错误。

最佳答案

根据 CXF，目标 URI 似乎不正确文档。
serviceName 的格式和 portName应该是 {namespace}name
尝试:

  • 服务名称={ http://www.webserviceX.NET/ }货币转换器
  • 端口名称={ http://www.webserviceX.NET/ }CurrencyConvertorSoap
