Hi,
JAX-RS ContainerRequestContext and ContainerResponseContext, as well as
WriterInterceptorContext and ReaderInterceptorContext filter contexts
all allow resetting the entity streams or on the way out - entity
objects - perhaps that can offer a simpler option for replacing the
content...
Cheers, Sergey

Hi!
I have following code (this is interceptror which does regular expression
replacements)
https://github.com/ilb/common/blob/master/common-jaxrs/src/
main/java/ru/ilb/common/jaxrs/interceptors/ReplaceOutInterceptor.java
private void replaceContents(Message message) {
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 contents = IOUtils.toString(csnew.getInputStream());
for (Map.Entry<String, String> keyValue :
replacements.entrySet()) {
contents = contents.replaceAll(keyValue.getKey(),
keyValue.getValue());
}
//String replaced=contents.replaceAll(regex, replacement);
os.write(contents.getBytes(Charset.forName(encoding)));
os.flush();
message.setContent(OutputStream.class, os);
} catch (IOException ioe) {
throw new RuntimeException(ioe);
}
}
Howewer, when response contents length of if less than threshold (128 *
1024 bytes)
i can get csnew.getInputStream() and get its contents, but when content is
more than treshold,
i see that in enforceLimits() -> createFileOutputStream() temp file is
created,
but using csnew.getInputStream() I am getting empty stream.
