我正在开发一个Spring-MVC应用程序。我有多个服务类，它们都被映射到一个控制器类。这是一种“笔记”应用程序。这就是有许多模型，服务的原因，但一切都在一个网页上。现在，我可以添加一个注释，删除一个注释，但编辑不起作用。之前我只有一个dao，model，service，controller，edit用来工作。现在我得到404.我发布了控制器和JSP / HTML文件。请看看。编辑没有工作，所以随意选择其中任何一个。任何，任何指针都会有所帮助。 控制器类：

通常，这些是使用Spring MVC获取404的最常见原因：
<jsp:include >个依赖项（这适用于整个包含链）检查您是否遇到任何问题。
