Question

我在下面编写了一个小应用程序，列出了使用Apache CXF库的所有方法和soap服务。此应用程序列出了服务的所有方法，但是当您运行此应用程序时在输出中可以看到，服务方法的输入参数和返回类型是复杂类型的JAXBElement。我希望cxf不生成JAXBElement，而是希望在运行时生成的原始类中使用复杂类型。正如在http://s141.codeinspot.com/q/1455881上所说的，可以通过为cxf库的wsdl2java实用程序将generateElementProperty属性的值设置为false来完成，但是我找不到与cxf库进行动态方法调用相同的参数。我想以原始类型获取输入参数和返回类型。

创建一个看起来像这样的绑定文件：

<jaxb:bindings
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.0"
  xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" jaxb:extensionBindingPrefixes="xjc">

  <jaxb:globalBindings generateElementProperty="false">
    <xjc:simple />
  </jaxb:globalBindings>
</jaxb:bindings>

并通过带有绑定文件列表的createClient方法将其传递给JaxWsDynamicClientFactory。
