Returns the length, in bytes, of the request body and made available by the input stream, or -1 if the length is not known ir is greater than Integer.MAX_VALUE.

Usage

From source file:org.apache.shiro.grails.SavedHttpServletRequest.java

public SavedHttpServletRequest(HttpServletRequest request) {
    super(request);

    // Copy the content from the request input stream to a byte array.
    int contentLength = request.getContentLength();
    ByteArrayOutputStream output = new ByteArrayOutputStream(contentLength == -1 ? 1024 : contentLength);
    try {/*from  w w w . ja v  a 2s  .  c  om*/
        IOUtils.copy(request.getInputStream(), output);
    } catch (IOException e) {
        throw new RuntimeException(e);
    }

    // Save the byte array (the request content) and the request parameters.
    savedContent = output.toByteArray();
    parameterMap = new Hashtable(request.getParameterMap());
