如何在ContainerRequestFilter中检索请求的匹配资源

问题描述

我正在使用JAX-RS/Jersey开发WebService.

I am working on a WebService using JAX-RS/Jersey.

我已经设置了 ContainerRequestFilter ，其目的是对用户进行身份验证.我只需要使用身份验证来保护某些路径，其余的路径就可以供所有人使用.

I've set up a ContainerRequestFilter whose purpose is to authenticate the user. I only need to protect some of the paths with authentication, the rest can be available to everyone.

我想通过我的ContainerRequestFilter中的ExtendedUriInfo检索matchedResources/matchedResults，以便我可以检查路径是否应受到保护.是否有一种方法可以创建一个过滤器，该过滤器在ExtendedUriInfo填充之后但在匹配的资源类和方法被调用之前被调用?

I want to retrieve matchedResources / matchedResults via ExtendedUriInfo in my ContainerRequestFilter so that I can check if the path should be protected or not. Is there a way to create a filter which is invoked after ExtendedUriInfo is populated, but before the matched resource class and method is invoked?

推荐答案

这是一个更通用的答案(例如，如果您使用的是像CXF这样的其他jax-rs实现):

Here is a more general answer (for instance if you're using another jax-rs implementation like CXF):

只需在您的过滤器类中添加以下内容作为实例变量:

Just add the following in your filter class as an instance variable:

ResourceInfo信息；

ResourceInfo info;

"javax.ws.rs.container.ResourceInfo是一个新的JAX-RS上下文，它可以 被注入到过滤器和拦截器中，并检查哪个资源 类和方法即将被调用."

"javax.ws.rs.container.ResourceInfo is a new JAX-RS context which can be injected into filters and interceptors and checked which resource class and method are about to be invoked."
