websocket - Why Spring SendToUser does not work -

i followed instruction spring send response particular user, not broadcast message instead.but in end, no response message can sent back.

this js code:

var stompclient = null; function setconnected(connected) {     document.getelementbyid('connect').disabled = connected;     document.getelementbyid('disconnect').disabled = !connected;     document.getelementbyid('conversationdiv').style.visibility =              connected ? 'visible': 'hidden';     document.getelementbyid('response').innerhtml = ''; } function connect() {     var socket = new sockjs('reqsample');     stompclient = stomp.over(socket);     stompclient.connect({}, function(frame) {         setconnected(true);         console.log('connected: ' + frame);         stompclient.subscribe('user/queue/resp', function(resp) {             var body = json.parse(resp.body);             showresp('cmid:' + body.cmid + ',reqname:' + body.reqname                     + ',custno:' + body.custno + ',qty:' + body.quantity);         });         stompclient.subscribe('user/queue/errors', function(resp) {             var body = json.parse(resp.body);             showresp(body);         });     }); } function disconnect() {     stompclient.disconnect();     setconnected(false);     console.log("disconnected"); } function sendname() {     var name = document.getelementbyid('name').value;     stompclient.send("/app/req", {}, json.stringify({         'name' : name     })); } 

this controller:

@controller public class messagecontroller {     @messagemapping("/req")     @sendtouser("/queue/resp")     public respmessage greeting(reqmessage message, principal pc)         throws exception {     system.out.println("---- received message: " + message == null ? "null"             : message.getname());     system.out.println("---- received user info: " + pc.getname());     respmessage rm = new respmessage();     rm.setcmid("cm_01");     rm.setcustno("cust_02");     rm.setquantity("1000");     rm.setreqname(message.getname());     return rm;      }      @messageexceptionhandler     @sendtouser("/queues/errors")     public string handleexception(exception ex) {         system.out.println(ex);         return ex.getmessage();     }      } 

this spring configuration:

<context:component-scan base-package="wx.poc7" /> <mvc:annotation-driven /> <bean     class="org.springframework.web.servlet.view.internalresourceviewresolver">     <property name="prefix" value="/web-inf/jsp/" />     <property name="suffix" value=".jsp" /> </bean> <mvc:resources mapping="/js/**" location="/js/" /> <websocket:message-broker     application-destination-prefix="/app" user-destination-prefix="/user">     <websocket:stomp-endpoint path="reqsample">         <websocket:sockjs />     </websocket:stomp-endpoint>     <websocket:simple-broker prefix="/queue, /topic" />  </websocket:message-broker> 

pls help. thx in advance.

i have tried use @sendtouser ,@sendtouser("/queue/resp") , simpmessagingtemplate well, totally cannot respond message browser.

user destinations prefix /user seems missing / in subscription destination. change user/queue/resp /user/queue/resp receive messages on client side.
