【问题标题】：Spring MVC Setup not working - Path issue?Spring MVC 设置不起作用 - 路径问题？

【问题描述】：

当我输入 /localhost:8080/springapp2/ 时，我收到以下消息

 HTTP Status 404 - Servlet spring is not available

即使是根 URL 也不起作用。

这是我的文件...

控制器类

 package org.nara.controllers;

 import javax.servlet.http.HttpServletResponse;

 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="/")
 public class HelloWorldControllder {

   public String HelloWorld() {
    return "hello";
}

@RequestMapping(value="/greetme", method = RequestMethod.GET)
public ModelAndView handlePOST( HttpServletRequest request, HttpServletResponse response) {
    ModelAndView mav = new ModelAndView("index.jsp");
    mav.addObject("Greeting", "Hello you");
    return mav;
 }  
}

【问题讨论】：

类路径中有弹簧罐吗？从 tomcat 日志中发布异常跟踪。
罐子不是问题。一切都很好。我解决了。

标签： java spring jsp model-view-controller

【解决方案1】：

我解决了这个问题。我改变了几件事。

将 URL 模式更改为 /
向类路径添加了 spring 表达式 jar
ContextConfigLocation URL 存在问题。我更新了它

现在它就像一个魅力。希望这对某人有所帮助。
