是否可以在没有MVC的情况下使用stock over sockjs.所以我想在tomcat中有spring rest接口,而angular2应用程序由express运行.

WebSocketConfig.java

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        // the endpoint for websocket connections
        registry.addEndpoint("/portfolio").setAllowedOrigins("*").withSockJS();
    }

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

SocketController.java

@Controller
public class SocketController {

    @Autowired
    private SimpMessagingTemplate template;

    public SocketController() {
        int a = 5;
    }

    @MessageMapping("/greeting")
    public String handle(String greeting) {
        return "[" + "greeting" + ": " + greeting;
    }
}

和打字稿代码:

...

constructor() {

        var socket = new …

当我输入到该组件时,我有url/app的父组件,默认情况下,下面的组件加载了以下路由:

@Routes([
   { path: '/users', component: UserComponent },
   { path: '/other', component: OtherComponent }
])

我正在实现OnInit接口:

ngOnInit() {
    this.router.navigate(['users'], this.currSegment);
}

由于父路由是/ app而child正在实现ngOnInit,我可以导航到用户,但如果我想直接通过url导航到路由/其他,则不可能.
