如何使用 Apache camel 使用 cxf 组件调用第三方 Web 服务 [英] How to call a third party webservice using Apache camel using cxf componnet
本文介绍了如何使用 Apache camel 使用 cxf 组件调用第三方 Web 服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我浏览了 Apache camel 网站和 camel in action 上的示例，它们都非常关注公开 Web 服务.我在网上找到的唯一示例不起作用.
I went through the example on Apache camel website and camel in action and both focus heavily on exposing a webservice. The only example I found online does not work.
我正在尝试访问第三方网络服务 wsdl - http://www.webservicex.net/CurrencyConvertor.asmx?WSDL
I am trying to access a third party webservice wsdl - http://www.webservicex.net/CurrencyConvertor.asmx?WSDL
此服务具有计算货币汇率的操作/方法.操作名称为ConversionRate".
This service has a operation/method that calculates the currency rate. The operation name is "ConversionRate".
我这样定义路线 -
<?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
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.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="${body}"/>
<to uri="cxf://http://www.webservicex.net/CurrencyConvertor.asmx?wsdlURL=http://www.webservicex.net/CurrencyConvertor.asmx?wsdl&serviceName=CurrencyConvertor&portName=http://www.webserviceX.NET/tns:CurrencyConvertorSoap&dataFormat=MESSAGE"/>
<log message="${body}"/>
</route>
</camelContext>
</beans>
我已将示例有效负载 xml 定义为 -
I have defined the sample payload xml as -
<order>
<Id>1</Id>
<Price>10.00</Price>
<Quantity>2</Quantity>
</order>
我在运行此示例时收到此错误.
I am getting this error when I run this example.

推荐答案
根据 CXF 文档.
serviceName 和 portName 的格式应该是 {namespace}name
The format for serviceName and portName should be {namespace}name
尝试:
- serviceName={http://www.webserviceX.NET/}CurrencyConvertor
- portName={http://www.webserviceX.NET/}CurrencyConvertorSoap
- serviceName={http://www.webserviceX.NET/}CurrencyConvertor
- portName={http://www.webserviceX.NET/}CurrencyConvertorSoap
