HomeController.java 

package com.google;    
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;   
@Controller
public class HomeController {       
    @RequestMapping("/")
    public String showMyPage() {
        return "main-menu";
    }           
}

我已经创建了main-menu.jsp页面，并将其保存在WEB_INF的 view 文件夹中。同样这两个xml文件都在WEB-INF中。当我运行时，出现此异常。是由于init-params引起的，但我认为这是正确的，它应该可以正常工作。那么问题出在哪里，请帮忙。

答案 0 :(得分：0)

  

根本原因....       java.io.FileNotFoundException：无法打开ServletContext资源[/WEB_INF/spring-mvc-demo-servlet.xml]

发生错误，可能是因为标签<param-value> WEB_INF / spring-mvc-demo-servlet.xml </ param-value>中“ spring-mvc-demo-servlet.xml”的路径指定不正确
