当通过cxf jaxrs调用时传递日期输入：客户端

问题描述：

也许这是非常微不足道的，但不知何故，我一直无法找到为什么这不起作用！当通过cxf jaxrs调用时传递日期输入：客户端

我有一个通过CXF的JAXRS暴露的服务：服务器指令

<jaxrs:server id="specialServiceRS" 
    address="http://localhost:8080/specialServiceRS"> 
    <jaxrs:serviceBeans> 
     <ref bean="specialService" /> 
    </jaxrs:serviceBeans> 
    <jaxrs:providers> 
     <bean id="jaxbProvider" 
      class="org.apache.cxf.jaxrs.provider.JAXBElementProvider"> 
      <property name="marshallAsJaxbElement" value="true" /> 
      <property name="unmarshallAsJaxbElement" value="true" /> 
     </bean> 
     <bean class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"> 
      <property name="mapper" ref="jacksonMapper" /> 
     </bean> 
     <bean class="com.kilo.ProgressiveDateHandler" /> 
    </jaxrs:providers> 
</jaxrs:server> 
<bean id="jacksonMapper" class="org.codehaus.jackson.map.ObjectMapper"> 
    <property name="serializationConfig.dateFormat"> 
     <bean class="java.text.SimpleDateFormat"> 
      <constructor-arg value="yyyyMMddHH:mm:ss.S" /> 
     </bean> 
    </property> 
    <property name="deserializationConfig.dateFormat"> 
     <bean class="java.text.SimpleDateFormat"> 
      <constructor-arg value="yyyyMMddHH:mm:ss.S" /> 
     </bean> 
    </property> 
</bean>

为了能够正确处理日期，我们增加了一个最新处理器 - ProgressiveDateHandler - 这ParameterHandler和ParamConverter。这似乎当通过浏览器调用做工精细 - 然而，当通过基于Java的客户端通过CXF的JAXRS配置调用：客户指令，

<jaxrs:client id="specialServiceClient" serviceClass="com.kilo.SpecialServiceImpl" 
    address="http://localhost:8080/specialServiceRS"> 
    <jaxrs:providers> 
     <bean class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"> 
      <property name="mapper" ref="jacksonMapper" /> 
     </bean> 
     <bean class="com.kilo.ProgressiveDateHandler" /> 
    </jaxrs:providers> 
</jaxrs:client> 
<bean id="jacksonMapper" class="org.codehaus.jackson.map.ObjectMapper"> 
</bean>

我收到以下错误：

关于进一步调试，它看起来像它使用org.apache.cxf.jaxrs.provider.ProviderFactory $ LegacyParamConverter而不是我的ParamConverter即。 ProgressiveDateHandler。如果有人能指出哪里出了问题 - 大部分是我配置不正确的东西，我会非常感激，因为这在配置Handler时会被视为开箱即用。

在此先感谢！

P.S .:我有一个测试setup如果有人想看到它的行动。

看起来像使用正确的方式ParamConverter也是为了实现ParamConverterProvider接口以及here。

@SuppressWarnings("unchecked") 
@Override 
public <T> ParamConverter<T> getConverter(Class<T> rawType, 
     Type genericType, Annotation[] annotations) { 
    if (rawType == Date.class) { 
     return (ParamConverter<T>) this; 
    } 
    return null; 
}

不热乎的两个接口帮助实现同样的事情，谢尔盖的概念JSR-339邮件列表上说 - 但你必须遵循的规格！ :)

这似乎摆脱了错误 - 希望这可以帮助别人。另外，如果我采取了不正确的路线，请随时纠正我。谢谢！
