- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
你好我有一个 Spring MVC 4.0.4 项目完全使用 Wildfly 8.1 服务器内的注释配置,唯一的问题是当我使用以下 javascript 代码使用 Stompjs 初始化 Sockjs 时我得到一个我不明白的异常,为清楚起见,当我使用基于 XML 的配置时,这并没有发生,我使用此 link 中的教程
Javascript 代码
var socket = new SockJS('/frontend/track');
referencesServices.stompClient = Stomp.over(socket);
Weboscket java 配置
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
public static final Logger LOGGER = LogManager.getLogger(WebSocketConfig.class);
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
LOGGER.debug("INIT WEBSOCKET END POINTS");
registry.addEndpoint("/track").withSockJS();//.setDisconnectDelay(30000);
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/updates");
// registry.enableStompBrokerRelay("/queue/", "/topic/");
registry.setApplicationDestinationPrefixes("/app");
}
}
异常

更新
现在在 smoky 的帮助下,websocket 终于可以在 wildfly 8 上运行了,现在唯一的问题是当 sockjs 连接时抛出异常:

最佳答案
在运算符(operator)的帮助下:
首先,您需要使用最新的 undertow 库。有两种可能性,但我只测试了第一种:
在 modules\system\layers\base\io\undertow\
中更新 undertow 库:
我只更新了core
和 servlet
从 1.0.15.Final 到 1.1.0.Beta3 然后更新了两个 module.xml
使用新文件。
在您的项目中使用新的 undertow 库(例如使用 Maven)并使用 jboss-deployment-structure.xml
禁用该模块.
XML 应如下所示:
