java - HttpServletRequest.getParamter() return null in CXF Restful service(Post) -

i wrote web api using apache cxf. when use httpservletrequest.getparamter() in post method, return null.here code:

@path("/") public class tokenservice extends digiwinbaseservice {      private static void printrequest(httpservletrequest httprequest) {         system.out.println("\n\n headers");         enumeration headernames = httprequest.getheadernames();         while (headernames.hasmoreelements()) {             string headername = (string) headernames.nextelement();             system.out.println(headername + " = " + httprequest.getheader(headername));         }         system.out.println("\n\n parameters");         enumeration params = httprequest.getparameternames();         while (params.hasmoreelements()) {             string paramname = (string) params.nextelement();             system.out.println(paramname + " = " + httprequest.getparameter(paramname));         }         system.out.println("\n\n row data");         system.out.println(extractpostrequestbody(httprequest));     }      private static string extractpostrequestbody(httpservletrequest request) {         if ("post".equalsignorecase(request.getmethod())) {             scanner s = null;             try {                 s = new scanner(request.getinputstream(), "utf-8").usedelimiter("\\a");             } catch (ioexception e) {                 e.printstacktrace();             }             return s.hasnext() ? s.next() : "null";         }         return "null";     }      @post     @consumes("application/x-www-form-urlencoded")     public response authorize(@formparam("param") string param,             @formparam("param2") string param2,@context httpservletrequest httprequest) throws oauthsystemexception {         printrequest(httprequest);         system.out.println("param:"+param);         system.out.println("param2:"+param2);                return response.status(httpservletresponse.sc_ok).entity("ok").build();          } } 

here test code

   public class httpclienttest {          public static void main(string[] args) throws exception{              string url4 = "/api/services/test";             string host = "127.0.0.1";             httpclient httpclient = new httpclient();             httpclient.gethostconfiguration().sethost(host, 8080, "http");             httpmethod method = postmethod(url4);             httpclient.executemethod(method);                    string response = method.getresponsebodyasstring();             system.out.println(response);         }          private static httpmethod postmethod(string url) throws ioexception{              postmethod post = new postmethod(url);             post.setrequestheader("content-type","application/x-www-form-urlencoded;charset=gbk");               namevaluepair[] param = {                      new namevaluepair("param","param1"),                     new namevaluepair("param2","param2"),} ;             post.setrequestbody(param);             post.releaseconnection();             return post;         }     } 

here print out :

headers content-type = application/x-www-form-urlencoded;charset=gbk user-agent = jakarta commons-httpclient/3.1 host = 127.0.0.1:8080 content-length = 26  parameters  row data null  param:param1 param2:param2 

why parameters null? how can post params using httpservletrequest.getparamter()

cxf consuming post data fill formparams.

https://issues.apache.org/jira/browse/cxf-2993

the resolution "won't fix". in issue, suggest use multivaluedmap recover params, or use httpservletrequest

option 1

@post @consumes("application/x-www-form-urlencoded") public response authorize( multivaluedmap<string, string> parametermap, @context httpservletrequest httprequest) throws oauthsystemexception {      //parametermap has post parameters 

option 2

@post @consumes("application/x-www-form-urlencoded") public response authorize( @context httpservletrequest httprequest) throws oauthsystemexception {     //httprequest.getparametermap() has post parameters
