如何修改出站CXF请求的原始XML消息？
如何修改出站CXF请求的原始XML消息？
提问于 2011-08-03 00:36:10
我想修改传出的SOAP请求。我想从信封的主体中删除2个xml节点。我设法设置了一个拦截器，并将生成的消息字符串值设置为端点。
但是，以下代码似乎不起作用，因为传出消息没有按预期进行编辑。有没有人有关于如何做到这一点的代码或想法？
public class MyOutInterceptor extends AbstractSoapInterceptor {
public MyOutInterceptor() {
super(Phase.SEND);
}
public void handleMessage(SoapMessage message) throws Fault {
// Get message content for dirty editing...
StringWriter writer = new StringWriter();
CachedOutputStream cos = (CachedOutputStream)message.getContent(OutputStream.class);
InputStream inputStream = cos.getInputStream();
IOUtils.copy(inputStream, writer, "UTF-8");
String content = writer.toString();
// remove the substrings from envelope...
content = content.replace("<idJustification>0</idJustification>", "");
content = content.replace("<indicRdv>false</indicRdv>", "");
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
outputStream.write(content.getBytes(Charset.forName("UTF-8")));
message.setContent(OutputStream.class, outputStream);

我今天也遇到了这个问题。在经历了许多痛苦之后，我终于能够修改CXF源代码附带的configuration_interceptor演示中的StreamInterceptor类：
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);
String soapMessage = IOUtils.toString(csnew.getInputStream());
...soapMessage变量将包含完整的SOAP消息。您应该能够操作soap消息，将其刷新到输出流，并执行message.setContent(OutputStream.class...调用以将您的修改放到消息上。这是没有保证的，因为我自己也是CXF的新手！
注意: CachedStream是StreamInterceptor类中的私有类。不要忘记将拦截器配置为在PRE_STREAM阶段运行，以便SOAP拦截器有机会编写SOAP消息。

基于第一条注释，我创建了一个抽象类，可以很容易地使用它来更改整个soap信封。
以防有人想要一个现成的代码部分。

以下是能够冒泡服务器端异常的方法。在以前的解决方案中使用os.close()而不是IOUtils.closeQuietly(os)也会导致异常。
public class OutInterceptor extends AbstractPhaseInterceptor<Message> {
public OutInterceptor() {
super(Phase.PRE_STREAM);
addBefore(StaxOutInterceptor.class.getName());
}
public void handleMessage(Message message) {
OutputStream os = message.getContent(OutputStream.class);
CachedOutputStream cos = new CachedOutputStream();
message.setContent(OutputStream.class, cos);
message.getInterceptorChain.aad(new PDWSOutMessageChangingInterceptor(os));
}
}
public class OutMessageChangingInterceptor extends AbstractPhaseInterceptor<Message> {
private OutputStream os;
public OutMessageChangingInterceptor(OutputStream os){
super(Phase.PRE_STREAM_ENDING);
addAfter(StaxOutEndingInterceptor.class.getName());
this.os = os;
}
public void handleMessage(Message message) {
try {
CachedOutputStream csnew = (CachedOutputStream) message .getContent(OutputStream.class);
String currentEnvelopeMessage = IOUtils.toString( csnew.getInputStream(), (String) message.get(Message.ENCODING));
csnew.flush();
IOUtils.closeQuietly(csnew);
String res = changeOutboundMessage(currentEnvelopeMessage);
res = res != null ? res : currentEnvelopeMessage;
InputStream replaceInStream = IOUtils.tolnputStream(res, (String) message.get(Message.ENCODING));
IOUtils.copy(replaceInStream, os);
replaceInStream.close();
IOUtils.closeQuietly(replaceInStream);
message.setContent(OutputStream.class, os);
} catch (IOException ioe) {
throw new RuntimeException(ioe);
}
}
