Mixing
commited response http servlet response in spring Java always
0
I have an Spring application, and I have a filter after.
My code is:
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
if (response.getCharacterEncoding() == null) {
response.setCharacterEncoding(StandardCharsets.UTF_8.toString());
}
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
try {
allowAccess = checkEncryption(httpServletRequest, httpServletResponse); // it returns a boolean Value
if (allowAccess) {
String bodyContent =
Utils.parseInputStreamToString(httpServletRequest.getInputStream());
String body = decryptMessage(bodyContent); // decrypt the message using some algorithm
HttpServletRequestWritableWrapper httpServletRequestWritableWrapper =
new HttpServletRequestWritableWrapper(httpServletRequest,
body.getBytes());
HttpServletResponseReadableWrapper responseWrapper =
new HttpServletResponseReadableWrapper(httpServletResponse);
httpServletRequestWritableWrapper.addHeader(HEADER_TRANSACTION_ID,
Long.toString(System.currentTimeMillis()) + UUID.randomUUID().toString());
chain.doFilter(httpServletRequestWritableWrapper, responseWrapper);
String encryptedResponse = encryptResponseContent(
new String(Hex.encode(responseWrapper.getResponseBody())), publicServerKey);
LOGGER.info("Encrypted Response = " + encryptedResponse + "n commites:"
+ httpServletResponse.isCommitted() + ", " + responseWrapper.isCommitted());
if (!httpServletResponse.isCommitted()) {
httpServletResponse.setContentType(MediaType.TEXT_PLAIN_VALUE);
httpServletResponse.resetBuffer();
httpServletResponse.getOutputStream().write(encryptedResponse.getBytes());
httpServletResponse.getOutputStream().close();
}
} else {
LOGGER.info("Invalid Access!!");
if (!httpServletResponse.isCommitted())
httpServletResponse.sendError(HttpServletResponse.SC_UNAUTHORIZED,
ERROR_MESSAGE_INVALID_PERMISSION);
}
} catch (Excetion e) {
LOGGER.info(""+e);
}
}
I have a request with a bad request that returns to me 401 unauthorized request, but if I change my request with a correct request and I call to my filter I have the httpServletResponse.isCommitted() = true always after first call.
I need send the correct response each time depending the request (if I change my request why the appears commit = true), How can fix it?
Thanks a lot.
