Question

我创建了一个SOAP拦截器，如CXF docs：

中所述

public class SoapMessageInterceptor extends AbstractSoapInterceptor {
    public SoapMessageInterceptor() {
        super(Phase.USER_PROTOCOL);
    }
    public void handleMessage(SoapMessage soapMessage) throws Fault {
        // ...
    }
}

并在Spring的应用程序上下文中将其注册到总线：

  <cxf:bus>
    <cxf:inInterceptors>
      <ref bean="soapMessageInterceptor"/>
    </cxf:inInterceptors>
  </cxf:bus>

  <jaxws:endpoint id="customerWebServiceSoap"
        implementor="#customerWebServiceSoapEndpoint"
        address="/customerService"/>

一切正常，直到我添加了REST服务：

  <jaxrs:server id="customerWebServiceRest" address="/rest">
    <jaxrs:serviceBeans>
      <ref bean="customerWebServiceRestEndpoint" />
    </jaxrs:serviceBeans>
  </jaxrs:server>

问题是SOAP拦截器现在也在REST请求上被触发，这会在调用REST服务时导致类强制转换异常。

<ns1:XMLFault xmlns:ns1="http://cxf.apache.org/bindings/xformat">
  <ns1:faultstring xmlns:ns1="http://cxf.apache.org/bindings/xformat">
    java.lang.ClassCastException: org.apache.cxf.message.XMLMessage
    cannot be cast to org.apache.cxf.binding.soap.SoapMessage
  </ns1:faultstring>
</ns1:XMLFault>

有没有办法只通过配置将拦截器限制为SOAP消息？

Answer 1

您可以将拦截器连接到单个端点而不是总线：

<jaxws:endpoint id="customerWebServiceSoap"
    implementor="#customerWebServiceSoapEndpoint"
    address="/customerService">
  <jaxws:inInterceptors>
    <ref bean="soapMessageInterceptor"/>
  </jaxws:inInterceptors>
</jaxws:endpoint>

Answer 2

您可以尝试像这样配置拦截器：

  <cxf:bus name="someBus">
    <cxf:inInterceptors>
      <ref bean="soapMessageInterceptor"/>
    </cxf:inInterceptors>
  </cxf:bus>

通过定义总线的name，根据文档，将总线标识为唯一的Spring bean。然后在JAX-WS端点配置中，您需要指定引用该名称的总线：

  <jaxws:endpoint id="customerWebServiceSoap"
        implementor="#customerWebServiceSoapEndpoint"
        address="/customerService"
        bus="someBus"/>

此bus应仅适用于此JAX-WS端点。
