如何为cxf soap请求添加自定义标头？(How to add a custom header to cxf soap requests?)

 我想使用cxf和spring soap webservices创建以下xml： 
 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:key="http://schema.to/WebService">
   <soapenv:Header>
      <key:Signing>asdasdasd</key:Signing>
   </soapenv:Header>
 
 如何才能做到这一点？ 如何设置命名空间和自定义标头标记元素？ 

I'd like to create the following xml by using cxf and spring soap webservices:
 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:key="http://schema.to/WebService">
   <soapenv:Header>
      <key:Signing>asdasdasd</key:Signing>
   </soapenv:Header>
 
How can this be done? How can I set the namespace and the custom header tag element?
