cxf 拦截器 ?报错

cxf 框架 搭建的webservice  客户端 配置了 outInterceptor  消息就发不到server  就超时报错。去掉这个拦截器 就好使了。。。。  但是这个拦截器  也没看出什么问题  。

流的问题？ client端流没关闭，server端收不到？   

跪求大神指点   

以下是这个拦截器代码:  

public class ClientOutInterceptor extends AbstractPhaseInterceptor<SoapMessage> {
    public ClientOutInterceptor() {
        super(Phase.PRE_STREAM);
    }

    public ClientOutInterceptor(String phase) {
        super(phase);
    }

    @Override
    public void handleMessage(SoapMessage message) throws Fault {
        try {
            OutputStream os = message.getContent(OutputStream.class);


            CachedStream cs = new CachedStream();

            message.setContent(OutputStream.class, cs);

            message.getInterceptorChain().doIntercept(message);

            CachedOutputStream csnew = (CachedOutputStream) message.getContent(OutputStream.class);
            InputStream in = csnew.getInputStream();

            String xml = IOUtils.toString(in);

            System.out.println(xml);
//            AESEncryptSafe aesEncryptSafe = new AESEncryptSafe("Kijhr3(dwjnJR6");
//            xml = aesEncryptSafe.encrypt(xml);
            //这里对xml做处理，处理完后同理，写回流中
            IOUtils.copy(new ByteArrayInputStream(xml.getBytes("UTF-8")), os);

            cs.close();
            os.flush();

            message.setContent(OutputStream.class, os);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    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 {
        }

    }
}
