我正在创建一个 OAuth 授权服务器,它使用 Spring Security 作为我的部分 servlet 周围的安全层。其中一个重要部分是使用DelegatingFilterProxy
映射到springSecurityFilterChain bean,它需要一个WebApplicationContext
实例。
标准解决方案是包含一个ContextLoaderListener
关联的contextConfigLocation配置。但这需要为 root 创建一个单独的配置,WebApplicationContext
在我看来,这会使事情变得不必要地复杂化。
根据 Spring MVC 文档,每个DispatcherServlet
都有自己的WebApplicationContext
实例。更重要的是,通过阅读 的代码DelegatingFilterProxy
,应该可以WebApplicationContext
在构建时注入一个实例。
所以我的问题是:我可以将 DispatcherServlet WebApplicationContext 设置为 DelegatingFilterProxy 的实例吗?
这是我目前的相关配置:
