使用@RequestMapping匹配URL模式

您需要在上加上斜线

@RequestMapping

@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：

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

您不能尝试这样：

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

就像Leonel所说的那样，您应该使用完整的URL（

@RequestMapping(value ={"/activate/{key}"}

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