[英]Spring: Logging outgoing HTTP requests
I am trying to log all the outgoing Http requests in my spring based web application. 我试图在基于Spring的Web应用程序中记录所有传出的Http请求。 Is there is interceptor for this purpose?
是否有用于此目的的拦截器? I want to log all outgoing the contents and headers before it leaves the application.
我要记录所有传出的内容和标头,然后再离开应用程序。 I am using
spring-ws
to send SOAP requests. 我正在使用
spring-ws
发送SOAP请求。 So basically, I want to log not only the SOAP request xml (as mentioned here How can I make Spring WebServices log all SOAP requests? ) but the http request as a whole. 因此,基本上,我不仅要记录SOAP请求xml(如此处所述, 如何使Spring WebServices记录所有SOAP请求? ),还要记录整个HTTP请求。
Intercept the request/response using a ClientInterceptor
on the WebServiceGatewaySupport
: 使用
WebServiceGatewaySupport
上的ClientInterceptor
拦截请求/响应:
// 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;
}
...
To get the headers as well you need an instance of TransportOutputStream
. 要获得标头,还需要一个
TransportOutputStream
实例。 Unfortunately the class is abstract, so you need to subclass is. 不幸的是,该类是抽象的,因此您需要将其子类化。 Here's how it might look:
这是它的外观:
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;
}
}
