在Spring中，上下文注释有什么作用? [英] What does context annotation do in Spring?

问题描述

在Rest API设计中，我想知道上下文注释的确切目的是什么?

In Rest API design, I am wondering what the exact purpose of the context annotation is?

private HttpServletRequest request;

 @Context
 public void setRequest(final HttpServletRequest req) {
        request = req;
 }

推荐答案

目的是指示应从上下文中设置request属性.

The purpose is to indicate that the request property should be set from the context.

@Context用于从此处:

通常，@ Context可用于获取与请求或响应相关的上下文Java类型.

In general @Context can be used to obtain contextual Java types related to the request or response.

API文档(并不是非常有用的IMO.或者，也许更准确地说，是非常有用的.)

API docs (Not horribly useful IMO. Or, perhaps more accurately, horribly-useful.)
