将 spring Websession 与 spring 反应式 Web 通量集成 [英] Integrating spring Websession with spring reactive web flux

问题描述

Spring 新的响应式 Web 通量 api 有一个新的 http 会话实现，位于 这里.我想将最新的 spring web session 集成到新的 spring 反应网络流量中.我似乎无法得到它，我尝试将它作为 bean 注入，但它不起作用.我想像往常一样用 HttpSession 注入它

There is a new implementation of http session for spring new reactive web flux api located here. I would like to integrate the latest spring web session in the new spring reactive web flux. I can't seem to get it, I tried injecting it as a bean, but it does not work. I would like to inject it like I usually do with HttpSession

类似的东西

@Autowired
Websession webSession;

推荐答案

由于 Spring WebFlux 是一个响应式 Web 框架，您不能期望 Web Session 作为 bean 注入(即使在请求范围内).在 Servlet 世界中，每个请求/响应都在单个线程中处理，这支持这些方法(即请求"范围).使用 WebFlux，一个给定的请求可以被多个线程处理.

Because Spring WebFlux is a reactive web framework, you can't expect the Web Session to be injected as a bean (even in the request scope). In the Servlet world, each request/response is processed in a single thread, which enables those approaches (i.e. the "request" scope). With WebFlux, a given request can be processed by multiple threads.

与当前请求/响应关联的 WebSession 实例实际上附加到 ServerWebExchange(参见 getSession).由于反应式编程模型的性质，您很可能会在 Reactor 运算符中访问该会话 - 因此您不能指望将此实例注入应用程序的其他位置.

The WebSession instance associated with the current request/response is actually attached to the ServerWebExchange (see getSession). Because of the nature of the reactive programming model, you're very likely to access that session within a Reactor operator - so you can't expect to inject this instance somewhere else in your application.
