Java 无法运行SpringWebSocket演示

我正在尝试运行SpringWebSocket的演示，但无法完全测试它。我正在使用Java7和Tomcat7.0.50。在服务器启动时，我没有收到任何错误，但是当我用js打开网页连接到它时，我发现404页没有找到。我不确定我在配置中是否缺少任何东西来运行它，以及如何从js端连接它

我有以下xml文件：

<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>

我从中调用的js是：

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);
};

运行tomcat时的控制台输出：

浏览器控制台输出：

我怎样才能成功地测试它

更新

我还尝试从这里运行公文包示例：正如@jhadesdev所建议的那样

但这也无济于事。当我运行

mvn tomcat7:run

时，我看到以下输出并在浏览器404上打开url

[INFO]Chrome扩展可以帮助您测试WebSocket

此外，您还可以查看我与Websockets一起使用的项目。
尝试在webapp中添加一个资产文件夹，其中提供了所有stomp和sockjs.js文件。看一看这个例子，它可以通过
mvn clean install jetty:run
运行

问题似乎是sockjs不在服务器上，或者某个路径错误。根据链接上的示例，stomp端点可以是：

然后在javascript中，端点可以这样调用：

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

其中
/spring-websocket-portfolio
是应用程序的根部署路径
 您的应用程序看起来不错

您应该使用应用程序的根上下文作为JavaScript请求的前缀，如下所示

您的应用程序是否注册其他筛选器或自定义MessageConverter？也许其他一些配置元素在这里起干扰作用

最新的投资组合示例肯定有效，下面是一些问题：

您能告诉我们有关您的客户端设置（浏览器、版本）的更多信息吗
您的浏览器是否支持websocket（测试它）
您是否也可以在匿名模式下尝试（可能是第三方浏览器扩展出现故障）
能否检查您的浏览器是否未使用HTTP代理来处理本地主机请求
您能检查一下Tomcat访问日志中是否有这个HTTP404吗？（看看你是否对这些或卡塔利纳有什么感兴趣的东西。出来吧？）
我也面临同样的问题。这条线索给了我足够的线索来解决这个问题。非常感谢

解决方案：
如果您在web.xml中配置了一个Spring MVC Dispatcher Servlet，并映射到url模式，如下所示

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/webui/*</url-pattern>
</servlet-mapping>

var socket = new SockJS('/contextPath/webui/hello');

注意：用应用程序上下文路径替换上下文路径。
DispatcherServlet是如何映射的？可能就是你要找的
我用这种方式解决了这个问题：
创建SockJS时，添加localhost:8080/
像这样

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

对我来说，解决方案是通过
WebSocketConfig
类在中启用
SockJS
：

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

你好，哈利。我认为问题在于，当您创建新的SockJS对象时，您错过了项目的根。您可以尝试var sock=newsockjs（“/myProject/hello”）；或者用c:url。@Evgeni我也试过了，但仍然是404:（@HarryJoy-您是否也尝试过完整的url？关于公文包示例-哪些url使用404响应？app root（）或sockjs info端点（）？您没有运行第二个Web服务器吗？正常情况下，两个程序不能同时在同一个端口上运行，但让我们尝试查看有问题的更新。我尝试了此操作，但不起作用。：（1.Google Chrome 33 2.是的3.尝试了，但结果相同4.不是。是的，我尝试在url中添加根上下文前缀，但也没有帮助。：：（帮助。谢谢。我注意到，当这个示例从Spring引导jar文件运行时，它工作正常，但当转换为war时，它确实需要上下文路径。
new SockJS('http://localhost:8080/spring-websocket-portfolio/portfolio')

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