如何在Spring MVC控制器的@RequestMapping路径中限制路由扩展？ [英] How do I restrict route extensions in @RequestMapping paths for Spring MVC controllers?

问题描述

我有一个很想完成的任务，但是似乎找不到有关Spring MVC路由的信息。我有一个非常简单的控制器，可将路径路由到视图：

I have a fairly simple task that I want to accomplish, but can't seem to find information for Spring MVC routing about it. I have a very simple controller that routes a path to a view:

@Controller
@RequestMapping(value = "/help")
public class HelpController {

    private static final String HELP = "help";

    @RequestMapping(method = RequestMethod.GET)
    public String help(Model model, Locale locale) {
        model.addAttribute("locale", locale);
        return HELP;
    }
}

如果我想抛出404 http://mysite.com/help.some.extension.is.entered ，但是Spring似乎将示例解析为/ help。 javadoc表示@RequestMapping批注只是一个servlet URI映射，但我认为/ help表示它必须完全匹配。

I would like to throw a 404 if http://mysite.com/help.some.extension.is.entered, but Spring seems to resolve the example to /help. The javadoc says that the @RequestMapping annotation is just a servlet URI mapping, but I thought /help means it needs to be an exact match. Any clarification would be appreciated.

推荐答案

对于Spring 4，解决起来很容易：

For Spring 4 it's pretty easy to solve:

<mvc:annotation-driven>
    <mvc:path-matching suffix-pattern="false" />
</mvc:annotation-driven>

所以您仍然可以使用 mvc：注释驱动作为您的配置。

So you still can use mvc:annotation-driven for your config.
