Question

我正在尝试在基于Spring的Web应用程序中记录所有传出的Http请求。为此目的是否有拦截器？我想在离开应用程序之前记录所有传出的内容和标题。我正在使用spring-ws发送SOAP请求。所以基本上，我不仅要记录SOAP请求xml（这里提到How can I make Spring WebServices log all SOAP requests?），还要记录整个http请求。

使用ClientInterceptor上的WebServiceGatewaySupport拦截请求/回复：

// soapClient extends WebServiceGatewaySupport
soapClient.setInterceptors(new ClientInterceptor[]{new ClientInterceptor() {
        @Override
        public boolean handleRequest(MessageContext messageContext) throws WebServiceClientException {
            ByteArrayOutputStream os = new ByteArrayOutputStream();
            try {
                messageContext.getRequest().writeTo(os);
            } catch (IOException e) {
                throw new WebServiceIOException(e.getMessage(), e);
            }

            String request = new String(os.toByteArray());
            logger.trace("Request Envelope: " + request);
            return true;
        }

        @Override
        public boolean handleResponse(MessageContext messageContext) throws WebServiceClientException {
            ByteArrayOutputStream os = new ByteArrayOutputStream();
            try {
                messageContext.getResponse().writeTo(os);
            } catch (IOException e) {
                throw new WebServiceIOException(e.getMessage(), e);
            }

            String response = new String(os.toByteArray());
            logger.trace("Response Envelope: " + response);
            return true;
        }
        ...

要获取标题，您需要TransportOutputStream的实例。不幸的是，这个类是抽象的，所以你需要子类化。以下是它的外观：

class ByteArrayTransportOutputStream extends TransportOutputStream {

    private ByteArrayOutputStream outputStream;

    @Override
    public void addHeader(String name, String value) throws IOException {
        createOutputStream();
        String header = name + ": " + value + "\n";
        outputStream.write(header.getBytes());
    }

    public byte[] toByteArray() {
         return outputStream.toByteArray();
    }

    @Override
    protected OutputStream createOutputStream() throws IOException {
        if (outputStream == null) {
            outputStream = new ByteArrayOutputStream();
        }
        return outputStream;
    }
}
