【中文标题】Spring Boot - WebSocket 握手期间出错【英文标题】：Spring Boot - Error during WebSocket handshake 【发布时间】：2019-07-01 21:24:48 【问题描述】：当我尝试在我的 Spring Boot 应用程序中使用 WebSocket 时，出现此错误：“WebSocket 连接到 'ws://localhost:8080/Moda/chatroomServerEndpoint' 失败：WebSocket 握手期间出错：意外响应代码：400”（默认.html-第 11 行）.. 我的目标：通过两个不同的选项卡发送消息（例如：在 Google Chrome 中）请帮助我！谢谢...

【问题讨论】：
【参考方案1】：试试
new WebSocket("ws://localhost:8080/Moda/chatroomServerEndpoint/websocket");
而不是
`new WebSocket("ws://localhost:8080/Moda/chatroomServerEndpoint");`
还要确保设置.setAllowedOrigins("*")
【讨论】：
如何设置 .setAllowedOrigins("*") ？可以给样品吗？ 我想他的意思是在 WebsocketBrokerConfiguration 类中添加该方法调用，在 registerStompEndpoints 类方法中，如下所示：registry.addEndpoint("/vrp-websocket") .setAllowedOrigins("*") .withSockJS();以上是关于Spring Boot - WebSocket 握手期间出错的主要内容，如果未能解决你的问题，请参考以下文章
