Spring 4 websocket和stomp - 未到达控制器

技术标签:
【中文标题】Spring 4 websocket和stomp - 未到达控制器【英文标题】:Spring 4 websocket And stomp - controller is not reached 【发布时间】:2014-04-22 14:14:44 【问题描述】:我使用的是spring的官方示例(Greeting example),位于:
http://spring.io/guides/gs/messaging-stomp-websocket/
一切似乎都很好,当我按下连接时,我可以看到正在建立与服务器的连接。
但是,连接后,当我向服务器提交“名称”时,我没有收到任何错误,也没有请求到达 GreetingController。
我试图将日志级别放在跟踪上,当我执行“发送”时看到以下行:
22 Ar 2014 17:10:52 DEBUG DispatcherServlet - Successfully completed request
22 Apr 2014 17:10:52 DEBUG ExceptionTranslationFilter - Chain processed normally

有什么想法吗?
P.S,这是我使用的js代码的一部分(与网站相同):
function connect()
var socket = new SockJS('/MyWebApp/hello');
stompClient = Stomp.over(socket);
stompClient.connect(, function(frame)
setConnected(true);
console.log('Connected: ' + frame);
stompClient.subscribe('/topic/greetings', function(greeting)
showGreeting(JSON.parse(greeting.body).content);
);
);
function disconnect()
stompClient.disconnect();
setConnected(false);
console.log("Disconnected");
function sendName()
debugger;
var name = document.getElementById('name').value;
stompClient.send("/app/hello", , JSON.stringify( 'name': name ));
【问题讨论】:
【参考方案1】:好吧,服务器正在捕获消息,但它对此无能为力。所以,我认为你应该:
-
注意这一行"config.setApplicationDestinationPrefixes("/app");"在 WebSocketConfig 类上;
确保您的 Controller 使用 @Controller 注释,方法使用 @MessageMapping("/hello"); 进行注释
【讨论】:
【参考方案2】:好的,我有一个spring配置问题,我没有扫描必要的bean目录。
【讨论】:
你能不能至少写下你把@ComponentScan
