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，我正在尝试理解 @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 有六个类的列表（应用程序， UriInfo ，请求， HttpHeaders ， SecurityContext ，提供商） 。但是，我在Web上找到了使用此注释与其他类型的代码，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) {

}

是否有可以与此批注一起使用的受支持类型列表？此列表是否在标准的实现之间发生变化？

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

我正在尝试使用Jersey，我担心我会编写无法移植到其他JAX的代码-RS实施。

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

铆接JAX-RS 规范定义了可以通过<$ c注入的所有标准类型$ c> @Context 。

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

但如果我是你，我会查阅你选择的提供商的具体文件，看看有什么可用。

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

例如，RESTEasy提供这些值来自 @Context 。同时，泽西岛提供这些。由于标准的上下文值，显然会有重叠。

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