我正在尝试为在Tomcat 7上运行的网络应用实施一些Websocket功能。我使用以下技术:
我遵循本指南(大致):http://g00glen00b.be/spring-angular-sockjs/
我的配置与指南类似,但我会在此处添加一些代码片段:
客户端:
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());
}
我在一个普通的Spring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:
服务器端错误:

它实际上是连接重置或断管。
将传输协议更改为非websocket路由(例如xhr-polling
)也无济于事。
知道在Magnolia中可能会导致长期存在的Websocket会话关闭它的连接吗?
答案 0 :(得分:2)
解决方案就是完全绕过Magnolia过滤链。
我只需要在Magnolia admincentral中创建一个全局绕过对象:Configuration>服务器/滤波器/旁路
class: info.magnolia.StartsWithURIVoter
pattern: /socket
连接不再重置或中断。
答案 1 :(得分:0)
在Mangolia 5中,它是' info.magnolia.voting.voters.URIStartsWithVoter',而不是' info.magnolia.StartsWithURIVoter'
