Spring 4 websockets 导致大量异常 [英] Spring 4 websockets causing tons of exceptions

问题描述

自从我们在 Spring 4 中开始使用 websockets 以来，我们的日志中到处都是这个例外:

Ever since we started using websockets in Spring 4, our logs are littered with this exception:

3 ERROR MessageBrokerSockJS-1 handler.XhrStreamingTransportHandler$XhrStreamingSockJsSession:276 - Terminating connection after failure to send message to client. This may be because the client has gone away (see https://java.net/jira/browse/SERVLET_SPEC-44)
