我已将 SockJS 服务的处理程序注册为
@Bean
public SimpleUrlHandlerMapping handlerMapping() {
SockJsService sockJsService = new DefaultSockJsService(sockJsTaskScheduler());
Map<String, Object> urlMap = new HashMap<String, Object>();
urlMap.put("/sockjs/cobrowse/agent/**", new SockJsHttpRequestHandler(sockJsService, coBrowseSockJsAgentHandler()));
urlMap.put("/sockjs/cobrowse/customer/**", new SockJsHttpRequestHandler(sockJsService, coBrowseSockJsCustomerHandler()));
urlMap.put("/sockjs/cobrowse/admin/**", new SockJsHttpRequestHandler(sockJsService, coBrowseSockJsAdminHandler()));
SimpleUrlHandlerMapping hm = new SimpleUrlHandlerMapping();
hm.setOrder(-1);
hm.setUrlMap(urlMap);
return hm;
}
但是，当我尝试使用已注册的 URL 之一从客户端调用时，它会引发异常！

这更令人惊讶，因为相同的代码一直运行到昨天 - 我这边没有重大变化。我的猜测是，这与弹簧罐有关，可能是每晚更新 - 我使用的是“4.0.0.BUILD-SNAPSHOT”，但是我没有以前的库！
在这里发布它，如果有人遇到过这个问题，同时我正在尝试获取旧的库来尝试 - 我不知道如何从官方回购中获得它（同一版本的旧版本！）。
