Session 在SpringWebSocket注释修饰的方法内调用会话对象时出错

使用：

CurrentStatusController.groovy 保存

会话

列表中人员的所有id

PersonID

，然后使用会话对象处理相同的方法

CurrentStatusController.groovy 第一个可用，最后一个不可用，错误消息如下：

ERROR springwebsocket.GrailsSimpAnnotationMethodMessageHandler  -
Unhandled exception Message: No thread-bound request found: Are you
referring to request attributes outside of an actual web request, or
processing a request outside of the originally receiving thread? If
you are actually operating within a web request and still receive this
message, your code is probably running outside of
DispatcherServlet/DispatcherPortlet: In this case, use
RequestContextListener or RequestContextFilter to expose the current
request.

如何使SpringWebSocket方法接受session对象？

SpringSession（）解决了这种情况！

@MessageMapping("/personExist")
@SendTo("/topic/personExist")
protected Boolean personExist(String personId) {
    return (session.personIds.contains(personId))
}
