Question

当我想访问我的网站时，我遇到以下错误：

The requested resource is not available.

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

你有解决方案吗？

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

MVC-调度-servlet.xml中

IndexController.java

package com.myblog.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping(value={"","/","home"})
public class IndexController {

    @RequestMapping(method=RequestMethod.GET)
    public ModelAndView init(){
         return new ModelAndView("index");
    }
}

Answer 1

您需要添加

<mvc:annotation-driven/>

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

使用您当前的配置，没有注册此类处理程序，因此无法处理您对/的请求。

Answer 2

首先，如果你没有在类路径上加载.xml文件，你需要加载它们

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
   classpath:spring/application-config.xml,
   /WEB-INF/conf/mvc-config.xml 
  </param-value>
 </context-param>

现在您需要执行以下操作以使用注释启用spring mvc

 <context:component-scan base-package="com.ekiras" />
 <mvc:annotation-driven />
 <tx:annotation-driven />

您需要启用注释和组件扫描以扫描项目中的所有注释。
