我正在尝试设置一个 Spring MVC 项目。我在下面发布了我的配置文件。 如果有人帮助我，我会非常高兴。

提前致谢， 就此而言， 塔尔哈。

以下是我建议的一些更改。

1. 由于您使用的是 Context Config Loader Listener，因此 DispatcherServlet 的 contextConfigLocation 参数值应该为空。根据配置，您似乎正在为您的应用程序获取 2 个不同的应用程序上下文。
2. 将 mvc-config.xml 文件包含在 applicationConfig.xml 文件中。
3. webmvc servlet 的 url 映射应该是 /* （而不是 *.*）。请注意，这样做将导致您的资源请求（例如
4. 您可能想缩减您的欢迎文件列表。
5. 注释使您的对象不再是 POJO，但它们确实减少了您需要的 spring 配置量。

DispatcherServlet url 模式的初始化参数

<init-param>
    <param-name>contextConfigLocation<:/param-name> 
    <param-value><:/param-value> 
</init-param>

webmvc servlet 的

/*
