Spring Webソケットのデモを実行できません

Spring Web Socketのデモを実行しようとしていますが、完全にテストすることはできません。 Java 7とTomcat 7.0.50を使用しています。サーバーの起動中にエラーが発生しませんが、jsでWebページを開いて接続すると、404ページが表示されませんそれを実行するための構成に何か欠けているのかどうか、そしてそれをjs側からどのように接続できるのかわかりません。

次のxmlファイルがあります。

<beans ....>
    <context:annotation-config />

    <websocket:message-broker
        application-destination-prefix="/app">
        <websocket:stomp-endpoint path="/hello">
            <websocket:sockjs />
        </websocket:stomp-endpoint>
        <websocket:simple-broker prefix="/topic" />
    </websocket:message-broker>
</beans>

私のコントローラークラスは：

@Controller
public class SwsService {
    @MessageMapping("/hello")
    @SendTo("/topic/greetings")
    public Greeting greeting(HelloMessage message) throws Exception {
         return new Greeting("Hello, " + message.getName() + "!");
   }

    public String getGreeting() {
        return "Hello, you are in!";
    }
}

私がこれを呼んでいるjsは：

var sock = new SockJS("/hello");
sock.onopen = function () {
    console.log("open");
};
sock.onclose = function () {
    console.log("closed");
};
sock.onmessage = function (message) {
    console.log("msg", message);
};

Tomcatを実行したときのコンソール出力：

ブラウザコンソールの出力：

どうすればテストできますか？

アップデート

私もここからポートフォリオの例を実行してみました： https://github.com/rstoyanchev/spring-websocket-portfolio @jhadesdevによって提案されました

しかし、それも助けにはなりません。 mvn Tomcat7:runを実行すると、次の出力が表示され、ブラウザでURLを開くと404と表示されます。

そこにくっついて先に進みません。

私はその方法でこの問題を解決しました：SockJSを作成するときに、次のようにlocalhost：8080 /を追加します

new SockJS('http://localhost:8080/spring-websocket-portfolio/portfolio')

私にとっての解決策は、SockJSをWebSocketConfigクラスで有効にすることでした：

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    registry.addEndpoint("/search")
            .setAllowedOrigins("*")
            .setHandshakeHandler(new DefaultHandshakeHandler())
            .withSockJS();
}
