出于某种原因,我的@PathVariable
注释完全不起作用,在进行一些谷歌搜索后,我没有找到其他有相同问题的人,这是代码:
@Controller
@RequestMapping("/bot")
public class BotController {
@RequestMapping(value = "/test", method = RequestMethod.GET)
public void test() {
System.out.println("test");
Store.INSTANCE.getChatBot().postMessage("test");
}
@RequestMapping(value = "/say/{text}", method = RequestMethod.GET)
public void say(final @PathVariable("text") String text) {
System.out.println("say: " + text);
Store.INSTANCE.getChatBot().postMessage(text);
}
}
这个可以用: http://localhost:8080/GithubHookSEChatService/bot/test
这个不行: http://localhost:8080/GithubHookSEChatService/bot/say/realtest
除了System.out.println("say: " + text)
没有执行外,我能提供的唯一线索是:
24-Aug-2014 17:25:21.611 WARNING [http-apr-8080-exec-24]
org.springframework.web.servlet.PageNotFound.noHandlerFound
No mapping found for HTTP request with URI
[/GithubHookSEChatService/bot/say/realtest] in DispatcherServlet with name 'dispatcher'
我无法找到线索,有人知道发生了什么吗?为什么后者不起作用?

24-Aug-2014 17:31:20.333 INFO [http-apr-8080-exec-40] org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping.registerHandler 将URL路径 [/bot/*] 映射到处理程序 'botController'
, 因为http://localhost:8080/GithubHookSEChatService/bot/test
可以工作。不过,在日志中我无法看到两个方法的确切映射关系。 - skiwi@ResponseBody
在void
返回类型的前面。 - Marko Topolnik@ResponseBody
对于查看请求是否成功非常有帮助 :) 在test
上我得到了一个空白页面,在say
上是 404。 - skiwi@RequestMapping(value = "/{text}", method = RequestMethod.GET)
可以与http://localhost:8080/GithubHookSEChatService/bot/realtest
一起使用,但是@RequestMapping(value = "/say/{text}", method = RequestMethod.GET)
仍然不能与http://localhost:8080/GithubHookSEChatService/bot/say/realtest
一起使用。 - skiwi
