CXF 传出拦截器获取始终为空的肥皂响应正文？

发布于 2024-11-16 18:02:30 字数 735 浏览 8 评论 0原文

我写了一个拦截器来测试。但我在拦截器中得到 Soap 消息体始终为空。

我的Cxf是Apache-CXF-2.4.0

bean.xml是这样的：

<cxf:bus>
    <cxf:outInterceptors>
        <ref bean="myOutSoapInterceptor"/>
  </cxf:outInterceptors>
</cxf:bus>

拦截器文件：

public class MySoapInterceptorImpl extends AbstractSoapInterceptor implements IMySoapInterceptor {

public MySoapInterceptorImpl()
{
    super(Phase.WRITE );
    addAfter(SoapOutInterceptor.class.getName());
}


public void handleMessage(SoapMessage msg) throws Fault {
    // TODO Auto-generated method stub
    String soapContent ;
    SOAPMessage sm = msg.getContent(SOAPMessage.class);

    /*sm is always null!*/
    }
 }

原文

I write a Interceptor for test. But I get Soap message body in the Interceptor is always null.

My Cxf is Apache-CXF-2.4.0

bean.xml is like this:

<cxf:bus>
    <cxf:outInterceptors>
        <ref bean="myOutSoapInterceptor"/>
  </cxf:outInterceptors>
</cxf:bus>

Interceptor file :

public class MySoapInterceptorImpl extends AbstractSoapInterceptor implements IMySoapInterceptor {

public MySoapInterceptorImpl()
{
    super(Phase.WRITE );
    addAfter(SoapOutInterceptor.class.getName());
}


public void handleMessage(SoapMessage msg) throws Fault {
    // TODO Auto-generated method stub
    String soapContent ;
    SOAPMessage sm = msg.getContent(SOAPMessage.class);

    /*sm is always null!*/
    }
 }

要从soap消息中获取响应xml，您可以使用“CacheAndWriteOutputStream”和“CachedOutputStreamCallback”。在回调类中，您可以在关闭流之前获取消息。比如说，我们的 LoggingInterceptor 是“wsLoggingOutInterceptor”，可以在上下文文件中进行如下配置：

<bean id="loggingInInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor"/>
<bean id="logOutInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>
<bean id="wsLoggingOutInterceptor" class="org.jinouts.webservice.logging.WSLoggingOutInterceptor"></bean>

   <cxf:bus>
        <cxf:inInterceptors>
            <ref bean="loggingInInterceptor"/>           
        </cxf:inInterceptors>
        <cxf:outInterceptors>
            <ref bean="logOutInterceptor"/>
            <ref bean="wsLoggingOutInterceptor"/>
       </cxf:outInterceptors>
    </cxf:bus>

请注意，这里我们还有一些可在 CXF jar 中使用的默认拦截器。
现在，在我们自己的拦截器中，我们可以按以下方式编写来记录输出响应消息，或者您也可以在此处进行编辑：

/**
 * @author asraf
 * [email protected]
 */
public class WSLoggingOutInterceptor extends AbstractLoggingInterceptor
{
    public WSLoggingOutInterceptor() 
    {
        super(Phase.PRE_STREAM );
    }

    @Override
    public void handleMessage ( Message message ) throws Fault
    {
        // TODO Auto-generated method stub
        OutputStream os = message.getContent ( OutputStream.class );
        CacheAndWriteOutputStream cwos = new CacheAndWriteOutputStream ( os);
        message.setContent ( OutputStream.class, cwos );

        cwos.registerCallback ( new LoggingOutCallBack ( ) );
    }

    @Override
    protected Logger getLogger ( )
    {
        // TODO Auto-generated method stub
        return null;
    }
}
class LoggingOutCallBack implements CachedOutputStreamCallback
{
    @Override
    public void onClose ( CachedOutputStream cos )
    {
        try
        {
            if ( cos != null )
            {
                System.out.println ("Response XML in out Interceptor : " + IOUtils.toString ( cos.getInputStream ( ) ));
            }

        }
        catch ( Exception e )
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }       
    }

    @Override
    public void onFlush ( CachedOutputStream arg0 )
    {

    }   
}

To get the response xml from the soap message, you can use the "CacheAndWriteOutputStream" and "CachedOutputStreamCallback". In the callback class you can get the message before closing the stream. Say, our out LoggingInterceptor is "wsLoggingOutInterceptor" which can be configured in the context file as follows :

<bean id="loggingInInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor"/>
<bean id="logOutInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>
<bean id="wsLoggingOutInterceptor" class="org.jinouts.webservice.logging.WSLoggingOutInterceptor"></bean>

   <cxf:bus>
        <cxf:inInterceptors>
            <ref bean="loggingInInterceptor"/>           
        </cxf:inInterceptors>
        <cxf:outInterceptors>
            <ref bean="logOutInterceptor"/>
            <ref bean="wsLoggingOutInterceptor"/>
       </cxf:outInterceptors>
    </cxf:bus>

Note that, here we have also some default interceptor which is available with the CXF jars.
Now in our own interceptor we can write in the following way to log the output response message or you can also edit here :

/**
 * @author asraf
 * [email protected]
 */
public class WSLoggingOutInterceptor extends AbstractLoggingInterceptor
{
    public WSLoggingOutInterceptor() 
    {
        super(Phase.PRE_STREAM );
    }

    @Override
    public void handleMessage ( Message message ) throws Fault
    {
        // TODO Auto-generated method stub
        OutputStream os = message.getContent ( OutputStream.class );
        CacheAndWriteOutputStream cwos = new CacheAndWriteOutputStream ( os);
        message.setContent ( OutputStream.class, cwos );

        cwos.registerCallback ( new LoggingOutCallBack ( ) );
    }

    @Override
    protected Logger getLogger ( )
    {
        // TODO Auto-generated method stub
        return null;
    }
}
class LoggingOutCallBack implements CachedOutputStreamCallback
{
    @Override
    public void onClose ( CachedOutputStream cos )
    {
        try
        {
            if ( cos != null )
            {
                System.out.println ("Response XML in out Interceptor : " + IOUtils.toString ( cos.getInputStream ( ) ));
            }

        }
        catch ( Exception e )
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }       
    }

    @Override
    public void onFlush ( CachedOutputStream arg0 )
    {

    }   
}
