CXF 上的动态方法调用和 JAXBElement 类型

Question

我编写了下面的小应用程序来列出使用 Apache CXF 库的所有方法和肥皂服务。此应用程序列出了服务的所有方法，但正如您在运行此应用程序时在输出中看到的那样，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其原始类中的复杂类型。正如http://s141.codeinspot.com/q/1455881 所说，可以通过将 cxf 库的 wsdl2java 实用程序的 generateElementProperty 属性值设置为 false 来完成，但是我找不到与 cxf 库的动态方法调用相同的参数。我想获取原始类型的输入参数和返回类型。

Answer 1

创建一个如下所示的绑定文件：

<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>

并通过获取绑定文件列表的 createClient 方法将其传递到 JaxWsDynamicClientFactory。
