spring mvc 注解@RequestAttribute 类似于@RequestParam [英] spring mvc annotation @RequestAttribute similar to @RequestParam

问题描述

我想添加一个类似于@RequestParam 的注释，尽管它从请求属性而不是请求参数中提取值...

I would like add an annotation similar to @RequestParam, though have it pull the values from the request attribute rather than the request param...

是否有示例或解释如何为此创建我自己的注释以及需要的处理程序/活页夹?

Is there an example or explanation how to create my own annotation for this and the handler / binder needed as well?

谢谢

标题为扩展 Spring MVC 的注释控制器"的博客条目回答了您的问题.由于 Stackoverflow 不允许我创建直接链接，因此 Google 可以找到它.

The blog entry with the title "Extending Spring MVC's annotation controller" answers your question. Google it to find it since Stackoverflow won't let me create the direct link.

基本上，您创建一个 @RequestAttribute 注释，然后创建一个自定义 WebArgumentResolver.

Basically you create an @RequestAttribute annotation and then a custom WebArgumentResolver.

博客条目有@RequestAttribute 和@SessionAttribute 的示例.

The blog entry has examples for @RequestAttribute and @SessionAttribute.

带有示例的 svn 目录在这里.

The svn directory with the examples is here.
