Question

我正在尝试使用CXF从Apache Camel调用Web服务，尝试将货币从一种货币转换为另一种货币，但由于端点解析，我无法调用它。如果有任何简单的教程如何从Apache Camel调用webservices请发布.. 提前谢谢..

CamelContext如下..

<?xml version="1.0" encoding="UTF-8" standalone="no"?><beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:cxf="http://camel.apache.org/schema/cxf" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        
    http://camel.apache.org/schema/spring  
    http://camel.apache.org/schema/spring/camel-spring.xsd">

  <camelContext trace="false" xmlns="http://camel.apache.org/schema/spring">
    <route>
    <from uri="file:src/data/order?noop=true"/>
        <log message="&gt;&gt;&gt; ${body}" loggingLevel="INFO"/>
        <to uri="cxf://http://www.webservicex.net/CurrencyConvertor.asmx?wsdlURL=http://www.webservicex.net/CurrencyConvertor.asmx?wsdl&amp;serviceName={http://www.webserviceX.NET/}CurrencyConvertor&amp;portName={http://www.webserviceX.NET/}CurrencyConvertorSoap&amp;dataFormat=MESSAGE"/>   
        <log message="&gt;&gt;&gt; ${body}" loggingLevel="INFO"/>
    </route>
</camelContext>

</beans>

我的order.xml是......

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
   <web:ConversionRate>
<web:FromCurrency>AUD</web:FromCurrency>
<web:ToCurrency>USD</web:ToCurrency>
</web:ConversionRate> 
  </soap12:Body>
</soap12:Envelope>

这是我在运行驼峰上下文时遇到的错误....

访问http://www.webservicex.net/CurrencyConvertor.asmx?wsdl时，您的日志会显示：

java.net.UnknownHostException

检查，是否可以访问互联网。或者，如果您位于代理服务器后面，则可以先设置适当的代理设置。查找有关here的更多信息。

也就是说，您的SOAP请求错过了web命名空间。没有适当的设置，服务器会抱怨。

xmlns:web="http://www.webserviceX.NET/"

我开始测试：

 final org.apache.camel.spring.Main main = new org.apache.camel.spring.Main();
 main.setApplicationContextUri("META-INF/spring/cxf-example.orig.xml");
 main.start();
