[Eric-A]

项目是SpringMVC Maven结构的
index.jsp 页面可以正常访问，访问controller的 地址却一直是404，各路大神 帮忙看下。。。
controller访问地址：http://localhost:8080/clt/larw/verify?signature=signature×tamp=timestamp&nonce=nonce&echostr=echostr

[KeepSayingNo]

你在后台的java工程写个测试类，对WeChatListener的verification进行测试，看能否打印出那些信息。

成功了 index页面可以访问 直接访问controller就报404

[魔都]

目前没看出来什么问题，但是你可以用简单的方式,试出来 比如@RequestMapping(value="larw//verify", method=RequestMethod.POST). 把这个@RequestMapping("/larw")去掉 @RequestParam String signature,@RequestParam String timestamp, @RequestParam String nonce, @RequestParam String echostr 参数用对象的方式传 verifyWechatConfig 这个是验证签证是否合法的吧 怎么名字叫什么config 名字取的不好

我把class上的RequestMapping去掉了，只在method上加上了RequestMapping，依然404.。。。

谢谢大家，问题已经解决了，原因是web module读取Service module 有问题。。。

[LHuiMail]

No mapping found for HTTP request with URI [/clt/larw/verify] in DispatcherServlet with name 'default-dispatcher' 控制台有没有这条信息？

[叫啥名字好呢？]

原因是web module读取Service module 有问题。。。 请问这个什么意思啊？？？求解答，入门小白跟视频学这儿controller这里已经卡了好几天了
