Spring (IntegrationFlowContext)：动态注册到同一个websocket服务器的新路径
Spring (IntegrationFlowContext)：动态注册到同一个websocket服务器的新路径
提问于 2020-02-26 06:21:21
我试图使用JavaDsl实现spring解决方案，方法是遵循链接即https://github.com/joshlong/techtips/tree/master/examples/spring-integration-4.1-websockets-example
我通过订阅路径(即/messages)和我的stomp客户端成功地测试了它。
接下来，通过向IntegrationFlowContext注册集成流，我尝试了同样的方法。
它在服务器端成功执行，但是当我试图通过我的stomp客户端提出请求时，我收到了404的例外。
在浏览日志时，我发现以前"AbstractHandlerMapping“是映射到ResourceHttpRequestHandler的，现在是映射到ResourceHttpRequestHandler了。
与Spring管理的集成流(成功)

由于Mapped to ...中的getHandler(HttpServletRequest request)逻辑，您有一个不同的AbstractHandlerMapping
Object handler = getHandlerInternal(request);
if (handler == null) {
handler = getDefaultHandler();
}
if (handler == null) {
return null;
}
// Bean name or resolved handler?
if (handler instanceof String) {
String handlerName = (String) handler;
handler = obtainApplicationContext().getBean(handlerName);
}
HandlerExecutionChain executionChain = getHandlerExecutionChain(handler, request);
if (logger.isTraceEnabled()) {
logger.trace("Mapped to " + handler);
}我们不支持动态WS端点，因为我们没有在内部WebSocketHandlerMappingFactoryBean中扫描它们。
请随意提出一个GH问题的https://github.com/spring-projects/spring-integration/issues，我们将看看我们可以做什么。
