如题，求代码，在线等

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

import org.apache.cxf.binding.soap.interceptor.SoapPreProtocolOutInterceptor;
import org.apache.cxf.io.CachedOutputStream;
import org.apache.cxf.message.Message;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;

public class StreamInterceptor extends AbstractPhaseInterceptor<Message> {

    public StreamInterceptor() {
        super(Phase.PRE_STREAM);
        System.out.println("StreamInterceptor Initializing...");
        addBefore(SoapPreProtocolOutInterceptor.class.getName());
    }
    
    public void handleMessage(Message message) {
        boolean isOutbound = false;
        isOutbound = message == message.getExchange().getOutMessage()
               || message == message.getExchange().getOutFaultMessage();

        if (isOutbound) {
            OutputStream os = message.getContent(OutputStream.class);
            CachedStream cs = new CachedStream();
            message.setContent(OutputStream.class, cs);
            
            message.getInterceptorChain().doIntercept(message);

            try {
                cs.flush();
                CachedOutputStream csnew = (CachedOutputStream) message
                    .getContent(OutputStream.class);

                GZIPOutputStream zipOutput = new GZIPOutputStream(os);
                CachedOutputStream.copyStream(csnew.getInputStream(), zipOutput, 1024);
                cs.close();
                zipOutput.close();
                os.flush();

                System.out.println("------------- os = " + os);
                message.setContent(OutputStream.class, os);
            } catch (IOException ioe) {
                ioe.printStackTrace();
            }
        } else {
            try {
                InputStream is = message.getContent(InputStream.class);
                GZIPInputStream zipInput = new GZIPInputStream(is);
                message.setContent(InputStream.class, zipInput);
            } catch (IOException ioe) {
                ioe.printStackTrace();
            }
        }
    }

    public void handleFault(Message message) {
    }
    

    private class CachedStream extends CachedOutputStream {
        public CachedStream() {
            super();
        }
        
        protected void doFlush() throws IOException {
            currentStream.flush();
        }

        protected void doClose() throws IOException {
        }
        
        protected void onWrite() throws IOException {
        }
    }
}

并在配置文件中添加如下代码：
[code=Xml]
<cxf:bus>
<!--cxf:inInterceptors>
<ref bean="GZIPStream"/>
</cxf:inInterceptors>
<cxf:inFaultInterceptors>
<ref bean="GZIPStream"/>
</cxf:inFaultInterceptors-->
<!--cxf:outInterceptors>
<ref bean="GZIPStream" />
</cxf:outInterceptors-->
<!--cxf:outFaultInterceptors>
<ref bean="GZIPStream"/>
</cxf:outFaultInterceptors-->
</cxf:bus>
[/code]

感谢楼上提供的思路，本人已测通过。

我想问下，你怎么测的，怎么确定压缩是不是成功的？谢谢！

压缩前后的大小不一样噻。
