在CXF +简单前端+ Aegis数据绑定中,SOAP响应错误地反序列化为null

Question

我正在为SOAP Web服务编写客户端.我正在使用CXF库.随着简单的前端.和宙斯盾数据绑定.服务器为Web方法提供Java接口(名为MediaService),然后在客户端项目中导入该接口.然后,我使用MediaService.aegis.xml文件来提供方法参数的名称(这些名称不能在命名时和序列化请求时).

这是我在客户端上使用的代码:

ClientProxyFactoryBean factory = new ClientProxyFactoryBean();
factory.setDataBinding(new AegisDatabinding());
factory.setServiceClass(MediaService.class);
factory.setAddress(urlMediaServer);
MediaService service = (MediaService) factory.create();
final List<Reference> listeReferences = service.sendMedia(bu, media);

服务接口是这样的:

public interface MediaService
{
    public List sendMedia(String bu, Media media) throws Exception;
}

我已启用XML流日志记录,以便我看到发送到服务器的XML流以及它返回的流.

以下是流:

请求:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <ns1:sendMedia xmlns:ns1="http://service.soclemedia.mycompany.com/">
            <ns1:bu>sc_phx</ns1:bu>
            <ns1:media>
                <ns2:productId xmlns:ns2="http://bo.soclemedia.mycompany.com">TEST_CODE</ns2:productId>
                <ns2:mediaName xmlns:ns2="http://bo.soclemedia.mycompany.com">test.png</ns2:mediaName>
            </ns1:media>
        </ns1:sendMedia>
    </soap:Body>
</soap:Envelope>

响应:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soap:Body>
        <sendMediaResponse xmlns="http://service.soclemedia.mycompany.com">
            <out xmlns="http://service.soclemedia.mycompany.com">
                <ns1:Reference xmlns:ns1="http://bo.soclemedia.mycompany.com">
                    <subType xmlns="http://bo.soclemedia.mycompany.com">standard</subType>
                    <typeMedia xmlns="http://bo.soclemedia.mycompany.com">photo</typeMedia>
                </ns1:Reference>
                <ns1:Reference xmlns:ns1="http://bo.soclemedia.mycompany.com">
                    <subType xmlns="http://bo.soclemedia.mycompany.com">standard</subType>
                    <typeMedia xmlns="http://bo.soclemedia.mycompany.com">photo</typeMedia>
                </ns1:Reference>
            </out>
        </sendMediaResponse>
    </soap:Body>
</soap:Envelope>

该服务被调用,它回复并且客户端收到正确的回复.但是在客户端中,进行Web Service调用的service.sendMedia(bu,media)行返回null.反序列化反序列化有问题.你知道出了什么问题以及如何解决它吗？

最好的祝福.

更新:

当我打电话给这个方法时,我忘了提到:

MediaService service = (MediaService) factory.create();

我收到此错误:

    ...

这是我的cxf.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:cxf="http://cxf.apache.org/core"
      xsi:schemaLocation="http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">
    <cxf:bus>
        <cxf:features>
            <cxf:logging/>
        </cxf:features>
    </cxf:bus> 
</beans>

更新2:

这是我的MediaService.aegis.xml:

<mappings>
    <mapping>
        <method name="sendMedia">
            <parameter index="0" mappedName="bu"/>
            <parameter index="1" mappedName="media"/>
            <return-type componentType="com.mycompany.soclemedia.bo.Reference" />
        </method>
    </mapping>
</mappings>

Answer 1

只是一个想法：

在我最近的一个项目中，CXF Web 服务在 Jetty 本地运行时工作正常，而在 Weblogic 容器中运行时所有顶级 Collection 都被反序列化为 null。

显然这是由 JAXB 中的一个已知错误引起的（抱歉，手头没有参考资料），解决方法是以这种方式包装集合：

public class Wrapper 
{ 
    private List<Reference> references; 
    ... 
}

并让 Web 服务在线路上处理该对象。

我希望这也适用于您的问题，如果运气不好的话:-)
