You can print the request type using   request getMethod      You can print all the headers as mentioned here   Enumeration lt String gt  headerNames   request getHeaderNames    while headerNames hasMoreElements        String headerName   headerNames nextElement      System out println  Header Name -     headerName      Value -     request getHeader headerName        To print all the request params  use this   Enumeration lt String gt  params   request getParameterNames     while params hasMoreElements      String paramName   params nextElement     System out println  Parameter Name -   paramName    Value -   request getParameter paramName        request is the instance of HttpServletRequest  You can beautify the outputs as you desire

If you want the content string and this string does not have parameters you can use      String line   null      BufferedReader reader   request getReader        while   line   reader readLine       null           System out println line

In case someone also want to dump response like me  i avoided to dump response body  following code just dump the StatusCode and Headers   static private String dumpResponse HttpServletResponse resp       StringBuilder sb   new StringBuilder         sb append  Response Status        resp getStatus                 String headers   resp getHeaderNames   stream                        map headerName - gt  headerName           resp getHeaders headerName                         collect Collectors joining              if  headers isEmpty              sb append  Response headers  NONE           else           sb append  Response headers    headers                  return sb toString

Rewrite  Juned Ahsan solution via stream in one line  headers are treated the same way    public static String printRequest HttpServletRequest req        String params   StreamSupport stream                Iterable lt String gt      - gt  req getParameterNames   asIterator    spliterator    false               map pName - gt  pName         req getParameter pName                collect Collectors joining   amp          return req getRequestURI           params      See also how to convert an iterator to a stream solution

This should be more helpful for debug  Answer from  Juned Ahsan will not specify full URL and will not print multiple headers parameters   private String httpServletRequestToString HttpServletRequest request        StringBuilder sb   new StringBuilder         sb append  Request Method        request getMethod                 sb append  Request URL Path        request getRequestURL                  String headers           Collections list request getHeaderNames    stream                map headerName - gt  headerName           Collections list request getHeaders headerName                  collect Collectors joining              if  headers isEmpty              sb append  Request headers  NONE           else           sb append  Request headers     headers                   String parameters           Collections list request getParameterNames    stream                map p - gt  p           Arrays asList  request getParameterValues p                  collect Collectors joining                           if  parameters isEmpty              sb append  Request parameters  NONE           else           sb append  Request parameters       parameters                     return sb toString
