Question

我想将邮件从服务器发送到连接的客户端。我试图通过使用Web套接字来做到这一点。但它没有用......

我的HTML视图中的Javascript代码：

socket = new WebSocket('ws://localhost:8080/messages');
socket.onmessage = function(e) {
    console.log(e);
 }

Spring配置类：

@Configuration
@EnableWebSocketMessageBroker
@Import(WebSocketAutoConfiguration.class)
public class WebSocketConfiguration extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(final MessageBrokerRegistry registry) {
        registry.enableSimpleBroker("/topic");
        registry.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/messages");
    }
}

发送消息的服务类：

@Service
public class MessageSender {

    @Autowired
    private SimpMessagingTemplate messagingTemplate;

    public void sendMessage(final String message) {
        this.messagingTemplate.convertAndSend("/", message);
    }
}

实际上客户端什么也没收到。必须设置什么目的地才能向客户端发送消息？

根据您的配置，您正在使用STOMP over WebSocket http://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html#websocket-stomp-enable

正确使用将是：

var socket = new WebSocket("/spring-websocket-portfolio/portfolio");
var stompClient = Stomp.over(socket);

stompClient.connect({}, function(frame) {
})

Open Dev控制台，STOMP打印好日志:)

带有Spring和HTML5的Web套接字
