request.getInputStream () – Allowed single read time. If we want to use this method more than once, we may need to perform a custom tedious task for the HttpServletReqestWrapper class. See my example of a complex shell below.
Public Class
MultiReadHttpServletRequest extends HttpServletRequestWrapper private ByteArrayOutputStream cachedBytes; public MultiReadHttpServletRequest (HttpServletRequest request) super (request); @ Crush public ServletInputStream getInputStream () throws an IOException if (cachedBytes == null) cacheInputStream (); return the just purchased CachedServletInputStream (); @ Crush public BufferedReader getReader () throws IOException return a new BufferedReader (new InputStreamReader (getInputStream ())); private void cacheInputStream () throws IOException / * * Buffer the input stream in the order in which it is read multiple times. For simplicity, I'll be using Apache.commons IOUtils. * / cachedBytes = new ByteArrayOutputStream (); IOUtils.copy (super.getInputStream (), cachedBytes); / * The input stream that reads the cached body test * / public fortunef CachedServletInputStream extends ServletInputStream private writing ByteArrayInputStream; Client CachedServletInputStream () / * Create a new input stream entirely from the cached request text * / input = new ByteArrayInputStream (cachedBytes.toByteArray ()); @ Crush public int read () throws an IOException return input.read ();
In my case, I track all incoming requests. I created a filter
Public class helper filter TracerRequestFilter
private fixed final logger LOG = LoggerFactory.getLogger (TracerRequestFilter.class); @ Crush publicly destroy unnecessarily () @ Crush the widely available void doFilter (ServletRequest, ServletResponse, FilterChain) throws an IOException, Servlet Exception last request HttpServletRequest = (HttpServletRequest); Try if (LOG.isDebugEnabled ()) Close MultiReadHttpServletRequest WrappedRequest New = MultiReadHttpServletRequest (req); // Debug payload information logPayLoad (wrappedRequest); chain.doFilter (wrappedRequest, response); like chain.doFilter (request, response); in the end LOG.info ("End of process");string sensitive getRemoteAddress (HttpServletRequest request) String ipAddress = req.getHeader ("X-FORWARDED-FOR"); in case (ip-address == null) ipAddress = req.getRemoteAddr (); return the IP address; unique void logPayLoad (HttpServletRequest) @ Crush open to public init (FilterConfig void arg0) throws ServletException
For me this works with both Servlets 2.5 and 3.0. I only see request parameters, both form encoded requests and Json bodies.
