Question

我有两个使用Spring websockets进行通信的Java应用程序。我使用ActiveMQ版本5.12.3。我在TomEE服务器上运行应用程序。这是我在tomee.xml中用于ActiveMQ的配置：

<Resource id="MyAppMessageBus" type="ActiveMQResourceAdapter">
    BrokerXmlConfig =  broker:(tcp://localhost:61616,ws://0.0.0.0:61614,stomp://0.0.0.0:61613)
    ServerUrl       =  tcp://localhost:61616
</Resource>

这是我连接的Java代码：

    if (brokerUrl.startsWith("ws")) {
        WebSocketClient transport = new StandardWebSocketClient();
        stompClient = new WebSocketStompClient(transport);
    }

    stompClient.setMessageConverter(new MappingJackson2MessageConverter());
    stompClient.setTaskScheduler(taskScheduler);
    stompClient.setDefaultHeartbeat(heartbeat);
    stompClient.connect(brokerUrl, handler);

我可以使用以下代理网址成功连接：ws：// localhost：61614

我想做的是使用安全的websockets连接。当我更改tomee.xml中的url以使用wss：//并在我的代码中更新brokerurl时，我得到以下异常：

有谁知道启用安全websockets的简单方法？我是否需要在我的代码中添加额外的传输或添加到我的服务器配置？

Answer 1

在代理配置中，您需要服务器端的“wss：// ...”传输连接器。

请参阅：http://activemq.apache.org/websockets.html

Answer 2

activemq不通过标准协议支持websocket，而只支持jetty（参见https://github.com/apache/activemq/blob/master/activemq-http/src/main/java/org/apache/activemq/transport/ws/WSTransportServer.java）

你在那里几乎没有选择：

尝试在tomee / lib中添加jetty jar（注意不要添加冲突的jar）
配置外部代理（独立的activemq）并让它连接到它上面

Spring Websockets / Stomp升级到安全的websockets
