CXF DynamicWebservice 客户端 dateTIme 转换为 XMLGregorianCalendar

Question

我的 webservice 参数之一是 java.util.Date 类型，当我生成 CXF 动态 webservice 客户端时，由于 JAXB 的默认行为，它被转换为 XMLGregorianCalendar。但是，由于托管在服务器上的 web 服务需要一个 Date 对象，所以当调用实际的 web 服务时会抛出 ClassCastException。

Caused by: java.lang.ClassCastException: java.util.Date cannot be cast to javax.xml.datatype.XMLGregorianCalendar
    at *.*.CloseSet_WrapperTypeHelper1.createWrapperObject(Unknown Source)
    at org.apache.cxf.jaxws.interceptors.WrapperClassOutInterceptor.handleMessage(WrapperClassOutInterceptor.java:103)
    ... 36 more

创建CXF Dynamic webservice客户端的代码如下：

private static JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory
            .newInstance();

...

private CachedClient getClient(String wsdlUrl) {
...
dcf.createClient(wsdlUrl, Arrays.asList(new String[]{"C:\\datebinding.xjb"}))
...
}

如果我使用 wsdl2java 工具创建类，使用相同的绑定文件，创建的类会将字段显示为 java.util.Date 类型

C:\>"c:\apache-cxf-2.2.12\apache-cxf-2.2.12\bin\wsdl2java" -b datebinding.xjb http://localhost:8080/MyWeb/MyService?wsdl

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "closeSet", propOrder = {
    "instanceId",
    "activationDate"
})
public class CloseSet {

    protected long instanceId;
    @XmlElement(type = String.class)
    @XmlJavaTypeAdapter(Adapter1 .class)
    @XmlSchemaType(name = "dateTime")
    protected Date activationDate;

如果绑定文件被删除

C:\>"c:\apache-cxf-2.2.12\apache-cxf-2.2.12\bin\wsdl2java" http://localhost:8080/MyWeb/MyService?wsdl

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "closeSet", propOrder = {
    "instanceId",
    "activationDate"
})
public class CloseSet {

    protected long instanceId;
    @XmlSchemaType(name = "dateTime")
    protected XMLGregorianCalendar activationDate;

所以我怀疑我的自定义绑定文件没有被 CXF 动态客户端获取。

通过将工厂类从 JaxWsDynamicClientFactory 更改为 DynamicClientFactory，我能够生成将 datetime 字段映射到 java Date 的动态客户端。仍然不确定为什么它不适用于 JaxWsDynamicClientFactory ;)
