找不到合适的默认RequestUpgradeStrategy [英] No suitable default RequestUpgradeStrategy found

问题描述

我正在尝试在Spring上运行Websocket（不是STOMP，而是常规的websocket），如图所示此处。但是，在完成本教程之后，我得到以下异常：

I'm trying to run Websocket on Spring (Not STOMP but regular websocket) as seen here. However, after following the tutorial, I get the following exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.socket.server.support.DefaultHandshakeHandler#0': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.web.socket.server.support.DefaultHandshakeHandler]: Constructor threw exception; nested exception is java.lang.IllegalStateException: No suitable default RequestUpgradeStrategy found

我在几个版本的最新的Tomcat（我认为它应该支持JSR 356）是一个Tomcat 7.0.50

I got this on several versions of Tomcat, the newest (which I assume really should have JSR 356 support) was a Tomcat 7.0.50

我可能做错了什么？

推荐答案

我只需更新到Tomcat 7.0.52即可解决此问题。

I was able to resolve this by simply updating to Tomcat 7.0.52.
