我已經將我的Tomcat從版本7升級到版本8.0.30。一切正常，直到一個WebService方法被調用，它應該返回一個結果。java.io.IOException：流關閉 - 在Tomcat 8上 - JavaMelody - JAX WS
[編輯：25.01.2016]看起來響應是空的，甚至找不到根標籤。
當我切換回Tomcat 7時，一切正常。 我不知道在哪裏尋找想法。你能幫我解決我的問題嗎？

下面是來自javamelody PayloadNameRequestWrapper
protected void initialize() throws IOException {
//name on a best-effort basis
name = null;
requestType = null;
final HttpServletRequest request = (HttpServletRequest) getRequest();
final String contentType = request.getContentType();

return;
}
if (!"POST".equalsIgnoreCase(request.getMethod())) {

return;
}

requestType = null;
} finally {

resetBufferedInputStream();
}
}
protected BufferedInputStream getBufferedInputStream() throws IOException {
if (bufferedInputStream == null) {
//workaround Tomcat issue with form POSTs
//see http://stackoverflow.com/questions/18489399/read-httpservletrequests-post-body-and-then-call-getparameter-in-tomcat
final ServletRequest request = getRequest();
request.getParameterMap();
//buffer the payload so we can inspect it
bufferedInputStream = new BufferedInputStream(request.getInputStream());
// and mark to allow the stream to be reset
bufferedInputStream.mark(Integer.MAX_VALUE);
}
return bufferedInputStream;
}
protected void resetBufferedInputStream() throws IOException {
if (bufferedInputStream != null) {
bufferedInputStream.reset(); // Exception happens here
}
}
我認爲可以爲您發佈的觸發異常 –
我加javamelody有些線路的方法有用 - PayloadNameRequestWrapper.java –
