Question

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;
}

但是当我尝试使用其中一个注册URL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 - 我身边的重大变化。我的猜测是，它与春季罐子有关，可能是每晚更新 - 我正在使用“4.0.0.BUILD-SNAPSHOT”，但后来我没有以前的库！

在这里发布，如果有人遇到这个，同时我试图抓住旧的libs试用 - 我不知道如何从官方仓库获得它（相同版本的旧版本！）。

我花了几个小时将我的代码与存储库进行比较，并试图弄清楚出了什么问题 - 当我有足够的信心我没有破坏任何东西时，我猜测它可能是由于最新的JAR。我使用maven所以我的repo今天早上更新了。由于libs来自Spring - 这个猜测必须持续！

我的猜测结果是正确的 - 当我用“4.0.0.BUILD-20130814.154539-172”之前的版本替换当前版本“4.0.0.BUILD-20130823.020236”时 - 问题得到了解决。非常感谢microsoft回收站！
