While retiring requested payload form HttpServeletRequest throwing Java Lang Illegal State Exception

Question

trying to retrieve that data for HttpServeletRequest object. But it throwing Java Lang Illegal State Exception:

getInputStream() has already been called for this request

try {
        String test = null;
        if (request.getMethod().equalsIgnoreCase(request.getMethod())) {
            test = request.getReader().lines().collect(Collectors.joining(System.lineSeparator()));
        }
    } catch (Exception ec) {
        logger.error("Exception newRemarksUpdated : " + ec.getMessage());
    }

you can only read this data once https://docs.oracle.com/javaee/7/api/javax/servlet/ServletRequest.html#getReader-- — Ryuzaki L, Jul 25 '19 at 13:04
ok . I used getInputStream() then also it is throwing error "getInputStream()has already been called for this request" — SYED WASEEM AHMED, Jul 25 '19 at 13:07

First, you are comparing object instance with itself. The condition for this if statement will always be true.

if (request.getMethod().equalsIgnoreCase(request.getMethod()))

Second, create an instance of your reader, so it will be easier to manipulate.

BufferedReader reader = request.getReader();
String collected = reader.lines()
        .collect(Collectors.joining(System.lineSeparator()));

Third, it seems like you are calling getInputStream() method twice, which cannot be done. You can read more about it in this post.

According the documentation you're not able to use both character-oriented and byte-oriented streams to read a request. I bet you called getInputStream() somewhere else. You should use similar approach everywhere.
