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

我有一个相当简单的任务想要完成，但似乎无法找到有关 Spring MVC 路由的信息.我有一个非常简单的控制器，可以将路径路由到视图:

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 http://mysite.com/help.some.extension.is.entered，我想抛出 404，但 Spring 似乎将示例解析为/help.javadoc 说 @RequestMapping 注释只是一个 servlet URI 映射，但我认为/help 意味着它需要完全匹配.任何澄清将不胜感激.

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，它很容易解决:

For Spring 4 it's pretty easy to solve:

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

所以你仍然可以使用 mvc:annotation-driven 作为你的配置.

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