使用@RequestMapping匹配URL模式 [英] Matching URL pattern with @RequestMapping

问题描述

这与这个问题非常相似，但我无法不知道如何匹配网址格式.

It's quite similar to this question, but I just couldn't figure out how to match the url pattern.

web.xml:

<servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/activate/*</url-pattern>
</servlet-mapping>

我的控制器:

@RequestMapping(value = {"activate/{key}"}, method = RequestMethod.GET)
public ModelAndView activate(@PathVariable(value = "key") String key) {
  ...
}

当我尝试访问localhost:9999/myApp/activate/123456789时，出现以下错误:

When I try to access localhost:9999/myApp/activate/123456789, I get the following error:

No mapping found for HTTP request with URI [/myApp/activate/123456789] in DispatcherServlet with name 'dispatcher'

我也尝试了<url-pattern>/*</url-pattern>，发生了同样的事情.

I also tried <url-pattern>/*</url-pattern>, same thing happens.

但是，通过将<url-pattern>/activate/*</url-pattern>更改为 <url-pattern>/**</url-pattern>没有错误出现，但我仍然得到404. 那么，如何映射此网址格式?

However, by changing <url-pattern>/activate/*</url-pattern> to <url-pattern>/**</url-pattern> no error appears, but i still get 404. So, how do I map this url pattern?

推荐答案

您需要在@RequestMapping上加上斜杠，例如:

You need to put slash on @RequestMapping, like:

@RequestMapping(value = {"/activate/{key}"}, method = RequestMethod.GET)
public ModelAndView activate(@PathVariable(value = "key") String key) {
  ...
}

无论如何，如果您想访问以下上下文:

Anyway, if you wat to get access to following context:

<servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/activate/</url-pattern>
</servlet-mapping>

您不能尝试以下操作:

@RequestMapping(value = {"/{key}"}, method = RequestMethod.GET)
public ModelAndView activate(@PathVariable(value = "key") String key) {
  ...
}

[已编辑]

就像Leonel所说的那样，您应该使用此配置来使用完整URL(@RequestMapping(value = {"/activate/{key}"}):

Like Leonel said, you should have this configuration to use with full URL (@RequestMapping(value = {"/activate/{key}"}):

<url-pattern>/</url-pattern>
