java - HttpMessageNotReadableException: Could not read document: Stream closed; -

i working spring boot , filtering requests using filters. filter being used have check user verification reading data request body (for have used httpservletrequestwrapper implementation). requestwrapper getting data expected , services working fine in filter. but, when on success, filter passes request main controller, getting stream closed exception follows:

   o.s.w.s.m.s.defaulthandlerexceptionresolver - failed read http message: org.springframework.http.converter.httpmessagenotreadableexception: not read document: stream closed; nested exception java.io.ioexception: stream closed 

here filter class:

@webfilter(urlpatterns = {"/getdocs" }) public class authenticationfilter implements filter{      private static logger logger = logger.getlogger(authenticationfilter.class);      @autowired     private userverificationservice userverificationservice;      @override     public void destroy() {         // todo auto-generated method stub      }      @override     public void dofilter(servletrequest arg0, servletresponse response, filterchain chain)             throws ioexception, servletexception {          logger.info("checking token in filter");         httpservletrequest request = (httpservletrequest) arg0;         docverificationrequestwrapper myrequestwrapper = new docverificationrequestwrapper((httpservletrequest) request);         string body = myrequestwrapper.getbody();         token token = null;         try {             jsonobject jsonobj = new jsonobject(body);             jsonobject tokenobj = (jsonobject) jsonobj.get("token");             gson gson = new gson();             token = gson.fromjson(tokenobj.tostring(), token.class);              if(null != token) {                     if(userverificationservice==null){                     servletcontext servletcontext = request.getservletcontext();                     webapplicationcontext webapplicationcontext = webapplicationcontextutils.getwebapplicationcontext(servletcontext);                     userverificationservice = webapplicationcontext.getbean(userverificationservice.class);                 }                     string verstatus = userverificationservice.verifyuser(token);                     logger.info("verstatus = "+verstatus);                     if(verstatus != null && verstatus.equalsignorecase("success")) {                         chain.dofilter(request, response);                       }else                         logger.error("invalid token");             }else {                     logger.error("token missing.");             }         } catch (jsonexception e) {                 logger.error("exception in authetication filter " + e);         }     }      @override     public void init(filterconfig arg0) throws servletexception {         // todo auto-generated method stub      }  } 

and here httpservletrequestwrapper implementation class:

public class docverificationrequestwrapper extends httpservletrequestwrapper {  private final string body;  public docverificationrequestwrapper(httpservletrequest request) throws ioexception {    super(request);    stringbuilder stringbuilder = new stringbuilder();    bufferedreader bufferedreader = null;    try {      inputstream inputstream = request.getinputstream();      if (inputstream != null) {        bufferedreader = new bufferedreader(new inputstreamreader(inputstream));        char[] charbuffer = new char[128];        int bytesread = -1;        while ((bytesread = bufferedreader.read(charbuffer)) > 0) {          stringbuilder.append(charbuffer, 0, bytesread);        }      } else {        stringbuilder.append("");      }    } catch (ioexception ex) {        throw ex;    } {      if (bufferedreader != null) {        try {          bufferedreader.close();        } catch (ioexception ex) {          throw ex;        }      }    }    body = stringbuilder.tostring();  }   @override  public servletinputstream getinputstream() throws ioexception {    final bytearrayinputstream bytearrayinputstream = new     bytearrayinputstream(body.getbytes());    servletinputstream servletinputstream = new servletinputstream() {      public int read() throws ioexception {        return bytearrayinputstream.read();      }      @override     public boolean isfinished() {         // todo auto-generated method stub         return false;     }      @override     public boolean isready() {         // todo auto-generated method stub         return false;     }      @override     public void setreadlistener(readlistener listener) {         // todo auto-generated method stub      }    };    return servletinputstream;  }   @override  public bufferedreader getreader() throws ioexception {    return new bufferedreader(new inputstreamreader(this.getinputstream()));  }   public string getbody() {    return this.body;  } } 

any suggestion, how resolve error?

i guess because instead of passing actual wrapper chain, you're passing original request. try this:

if(verstatus != null && verstatus.equalsignorecase("success")) {     chain.dofilter(myrequestwrapper, response);   } 

obviously, @ time when objectmapper trying read request body - request input stream closed since has been read wrapper.
