Question

我想修改我的代码以使其更精简。我的意图如下：

我写了一个RedirectServlet来处理所有的重定向，所以我使用url-pattern /pages/*来区分原始的dispatcherServlet的请求映射。
我还将dipatcherServlet的url模式映射到/do/**，因为它由于我不知道的原因而与redirectServlet冲突。但它给我带来了更多需要解决的问题。
我所有控制器中的@RequestMapping注释可能都有问题。我想指定具有多个分隔符的路径，就像/do/user/signup一样。但是有一个问题，路径无法正确解析，它返回404页面，这让我很沮丧。类似的东西：

输入状态报告

message / do / user / login

说明请求的资源不可用。

关于我的说法，我想知道：

如何配置spring mvc环境，以便我可以重定向到页面而无需在控制器中写入函数，就像：

@RequestMapping（ “submitArticleView”） public String submitArticleView（Model model）{ model.addAttribute（“article”，new Article（））; 返回“submitArticleView”; }

我想要<a href="xxx.jsp"></a>之类的内容并返回页面。

如何以精益方式使用@RequestMapping。

提前致谢。
