Websocket 收不到数据
Websocket can't receive data
我有一个 Angular 4 和 Java/Spring MVC / Jhipster 网站，我正在尝试使用 this tutorial 创建一个 websocket（它使用 sock-js 和 stomp.js).我可以连接到 websocket，但是当我尝试从 Java 代码向客户端发送数据时，没有任何反应。请帮帮我。
在下面，我只是想在我的浏览器中访问 http://localhost:9001/api/websocket/testSend，并观察它向任何订阅 /topic/messages 的客户端发送数据。
@GetMapping("/testSend")
@SendTo("/topic/messages")
public String testSend() {
return "testSend";
}
我知道我订阅了上面的内容，因为 stomp.js 连接后在 firebug 中说了以下内容：
>>> SUBSCRIBE
id:sub-0
destination:/topic/messages
我有的其他代码：
我有一个 .ts 文件有这个（注意订阅似乎永远不会触发）：
connect() {
const socket = new SockJS('/api/websocket/chat');
this.stompClient = Stomp.over(socket);
this.stompClient.connect({}, (frame) => {
// subscribe to the topic
this.stompClient.subscribe('/topic/messages', (messageOutput) => {
console.log(JSON.parse(messageOutput.body));
});
});
}
WebSocketConfig.java
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/app");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/api/websocket/chat")
.setAllowedOrigins("*").withSockJS();
}
如果您需要更多信息...我链接的示例确实有一种方法，您可以在其中输入用户名和消息，并将其发送到服务器（然后服务器会将其发送回所有客户端）。
发送消息的.ts代码为：
sendMessage() {
const from = $('#from').val();
const text = $('#text').val();
const msgBody = JSON.stringify({'from':from, 'text':text});
this.stompClient.send(
'/app/chat', {}, msgBody);
}
REST 服务如下所示：
@MessageMapping("/chat")
@SendTo("/topic/messages")
public OutputMessage send(Message message) throws Exception {
Thread.sleep(1000); // simulated delay
String time = new SimpleDateFormat("HH:mm").format(new Date());
return new OutputMessage(message.getFrom(), message.getText(), time);
}
但问题是当我点击 "send" 按钮时它显示 POST http://localhost:9001/api/websocket/chat/703/dvyy2lak/xhr_send?t=1548985676336 404 (Not Found)
编辑：似乎当我尝试发送消息时，出现以下错误。所以我认为这是我遇到的问题

When a STOMP endpoint is configured, the Spring application acts as the STOMP broker to connected clients.
我们无法按照问题中的描述将消息发送到 stomp 端点。
我们需要将消息发送到目标主题 /app/chat.

app.js
var stompClient = null;

var socket = new SockJS('/api/websocket/chat');

When a STOMP endpoint is configured, the Spring application acts as the STOMP broker to connected clients.
我们无法按照问题中的描述将消息发送到 stomp 端点。
我们需要将消息发送到目标主题 /app/chat.
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfiguration extends AbstractWebSocketMessageBrokerConfigurer{
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/app");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/api/websocket/chat")
.setAllowedOrigins("*").withSockJS();
}
}
app.js
var stompClient = null;
function connect() {
var socket = new SockJS('/api/websocket/chat');
stompClient = Stomp.over(socket);
stompClient.connect({}, function (frame) {
console.log('Connected: ' + frame);
stompClient.subscribe('/topic/messages', function (data) {
console.log("subscription is called");
console.log("data"+JSON.stringify(data));
});
console.log("sending message");
var msgBody = JSON.stringify({'from':'barath', 'text':'demo'});
stompClient.send('/app/chat', {}, msgBody);
});
}
$(function () {
connect();
});
