我有以下代码...
@Controller
@RequestMapping("/stomp/**")
public class StompController {
@MessageMapping("/hello")
@SendTo("/topic/greet")
public Greeting greet(HelloMessage message) throws Exception{
System.out.println("Inside the method "+message.getName());
Thread.sleep(3000);
return new Greeting("Hello, "+message.getName()+"!");
}
}
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/stomp/topic");
config.setApplicationDestinationPrefixes("/app");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/stomp/hello").withSockJS();
}
}
<script type="text/javascript">
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('/stomp/hello');
stompClient = Stomp.over(socket);
stompClient.connect({}, function(frame) {
setConnected(true);
console.log('Connected: ' + frame);
stompClient.subscribe('/stomp/topic/greet', function(greeting){
showGreeting(JSON.parse(greeting.body).content);
});
});
}
function disconnect() {
stompClient.disconnect();
setConnected(false);
console.log("Disconnected");
}
function sendName() {
var name = document.getElementById('name').value;
stompClient.send("/stomp/app/hello", {}, JSON.stringify({ 'name': name }));
}
function showGreeting(message) {
var response = document.getElementById('response');
var p = document.createElement('p');
p.style.wordWrap = 'break-word';
p.appendChild(document.createTextNode(message));
response.appendChild(p);
}
</script>
客户端代码似乎连接正常,但我没有看到控制台消息对我来说意味着“/stomp/app/hello”是错误的路径。正确的路径应该是什么?
我也试过 /app/stomp/hello no dice ...
更新
我可以删除@RequestMapping("/stomp/**")
并删除与 stomp 相关的东西,它适用于我的简单测试,但是,我需要它适用于不允许这样做的更复杂的应用程序。
