spring-boot - 使用 sprint-boot 的 web-socket 反向代理因错误 text_partial_writing 断开连接

Question

我正在使用这个web-proxy代码使用 spring-boot 进行反向 websocket 代理，它在初始连接期间工作，之后我得到以下错误

我在此处为 sendMessage添加了同步块，但在此行仍然出现相同的错误

是否有其他 java websocket 代理代码？

我尝试使用 spring-cloud-gateway 但它与 spring-starter-web 不兼容（由于代码中的 spring MVC 依赖性，我无法删除 web）
