Caused by: java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/dispatcher-servlet.xml]

这是因为我把 [/WEB-INF/dispatcher-servlet.xml]的位置换成了[config/springmvc/dispatcher-servlet.xml]

因此idea在原来的位置找不到这个文件,怎么办呢

原来还是在web.xml里面做文章, 添加两行代码即可, 就是在dispatcher的servlet申明的时候, 添加初始化路径

源代码: 

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.form</url-pattern>
    </servlet-mapping>

修改后的代码: 

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <init-param>
            <param-name>contextConfigLocation</param-name>    
        　　<param-value>classpath:config/springmvc/dispatcher-servlet.xml</param-value>   
　　　　 </init-param>

　　<load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>*.form</url-pattern>
</servlet-mapping>

之后, idea能找到dispatcher-servlet.xml文件, 问题解决!
