  • spring Websocket 报 No suitab le default RequestUpgradeStrategy found

    开始使用Tomcat8开发一切挺好的,但是公司的Paas平台上的服务器是Resin4.0.44,启动时包如下错误

    WARN o.s.web.context.support.XmlWebApplicationContext - Exception e

    后来我本地也是用resion,但是一切正常,google后发现添加如下包即可

    <dependency>
    <groupId>org.eclipse.jetty.websocket</groupId>
    <artifactId>websocket-server</artifactId>
    <version>9.2.17.v20160517</version>
    </dependency>
