Java 使用弹簧和x2B；SockJS+；踩木兰

我正在尝试为运行在Tomcat7上的web应用程序实现一些Websocket功能。我正在使用以下技术：

• （服务器）Spring Websocket+Spring消息传递
• （客户端）SockJS+Stomp.js

我大致遵循以下指南：

我的配置与指南类似，但我将在此处添加一些代码片段：

客户：

    s.socket = new SockJS('http://localhost:8181/.cckiosk/socket/test');
    //s.socket = new SockJS('http://localhost:8181/.cckiosk/socket/test', {}, { transports: ['xhr-polling'] });
    s.client = Stomp.over(s.socket);
    s.client.connect({}, onConnect);
    s.client.onclose = onDisconnect;

服务器：

@Configuration
@ComponentScan
@EnableWebSocketMessageBroker
public class ModuleWebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry broker) {
        //Prefix for messages FROM server TO client
        broker.enableSimpleBroker("/client");
        //Prefix for messages FROM client TO server
        broker.setApplicationDestinationPrefixes("/server");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/socket/test").setAllowedOrigins("*").withSockJS();
    }
}

控制器：

@MessageMapping("/socket/test")
@SendTo("/client/message")
public GenericMessage doSample(GenericMessage msg) {
    log.info("doSample: " + JsonUtil.jsonify(msg));
    return new GenericMessage(msg.getId(), msg.getMessage(), new Date());
}

我在香草春季应用程序中设置了一切，一切都很好

但是，当我将相同的代码移植到Magnolia模块时，代码停止工作，我可以看到以下错误：

客户端错误：

实际上是连接重置或管道断裂

将传输协议更改为非websocket协议（例如，

xhr轮询

）也无济于事

---

知道Magnolia中有什么会导致长期Websocket会话的连接关闭吗？

解决方案在于完全绕过Magnolia过滤链

我只需要在Magnolia admincentral:Configuration>server/filters/bypasses中创建一个全局旁路对象

class: info.magnolia.StartsWithURIVoter
pattern: /socket

并且连接不再重置或中断。

在Mangolia 5中，它是“info.magnolia.voting.votters.uristartswithvotter”，而不是“info.magnolia.StartsWithURIVoter”
