java - spring - jSTL - 错误 404 - 请求的资源不可用

Question

当我想访问我的网站时，出现以下错误:

The requested resource is not available.

我注意到问题出在 mvc-dispatcher-servlet.xml 文件中的 <mvc:resources mapping="/resources/**" location="../../resources/normalMode/"/> 行但我不知道为什么？

你有什么解决办法吗？

我的项目结构:

- src
  - main
    - java
      - com
        - myblog
          - controller
             -//all java files as controller
    - resources
       - normalMode
          - css
             - header.css
    - webapp
       - /WEB-INF
         - /pages 
           - mvc-dispatcher.xml
           - web.xml

Answer 1

你需要添加

<mvc:annotation-driven/>

到您的 mvc-dispatcher-servlet.xml。通过此配置(和组件扫描)，Spring 将扫描并注册使用 @RequestMapping 注释的 @Controller 方法。

使用您当前的配置，没有注册这样的处理程序，因此没有任何东西可以处理您对 / 的请求。
