getContentAsByteArray
public byte[] getContentAsByteArray()
Return the cached request content as a byte array.The returned array will never be larger than the content cache limit.
handleContentOverflow
protected void handleContentOverflow(int contentCacheLimit)
Template method for handling a content overflow: specifically, a request body being read that exceeds the specified content cache limit.The default implementation is empty. Subclasses may override this to throw a payload-too-large exception or the like.
- 参数:
contentCacheLimit- the maximum number of bytes to cache per request which has just been exceeded- 从以下版本开始:
- 4.3.6
