我可以使用 @Context 注释注入哪些对象? [英] What objects can I inject using the @Context annotation?

问题描述

我是 JAX-RS 的新手，我想了解 @Context 注释应该如何工作.

I'm new to JAX-RS and I'm trying to understand how the @Context annotation is supposed to work.

在 javadoc 处是六个类的列表(Application、UriInfo、Request、HttpHeaders、SecurityContext>、提供者).但是我在网上找到了将 this 注释用于其他类型的代码，例如:

At the javadoc there is a list of six classes (Application, UriInfo, Request, HttpHeaders, SecurityContext, Providers). However I find code on the web that use the this annotation with other types, for example:

@GET
public String something(@Context HttpServletRequest req) {

}

是否有可与此注释一起使用的受支持类型列表?此列表在标准实施之间是否会发生变化?

Is there a list of supported types that can be used with this annotations? Does this list change between implementation of the standard?

我目前正在试验 Jersey，但我担心我会编写无法移植到其他 JAX-RS 实现的代码.

I'm currently experimenting with Jersey and I'm worried that I'll write code that cannot be ported to other JAX-RS implementation.

推荐答案

引人入胜的 JAX-RS 规范 定义了您可以通过 @Context 注入的所有标准类型.

The riveting JAX-RS specification defines all the standard types you can inject via @Context.

但如果我是你，我只会查阅你选择的提供商的具体文档，看看有什么可用的.

But if I were you, I would just consult the specific documentation of your chosen provider to see what is available.

例如，RESTEasy 提供了这些值 通过 @Context.同时，Jersey 提供这些.显然，由于标准上下文值，会有重叠.

For example, RESTEasy provides these values via @Context. Meanwhile, Jersey provides these. Obviously there will be overlap because of the standard context values.
