在 Intellij 中设置 Spring MVC Maven "Hello World" webapp

Question

我正在尝试在 Intellij 中设置一个 spring webapp。我正在使用 Maven 来管理依赖项和本地 Tomcat 网络服务器。到目前为止，我已经使用 Spring MVC 模板创建了项目。

我基本上是按照本教程进行操作，但是使用 Intellij 13.1.6 并使用 Spring MVC 模板： http://alfasin.com/setting-up-spring-web-project-on-intellij-using-maven/

我认为这将使我能够快速启动 "Hello World" 应用程序并运行ning。但是，我遇到了 500 个内部错误，无法解决。

当我尝试运行应用程序时，我通常会遇到此错误：

似乎是随机的，但有时我会得到这个错误：

这是我的 web.xml 文件：

<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

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

</servlet>

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

这是我的 mvc-dispatcher-servlet.xml 文件：

这是我的控制器：

@RequestMapping("/")

{   
    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model)
    {
        model.addAttribute("message", "Hello world!");
        return "hello";
    }

这是我的 Tomcat 配置：

如果有人能指出我的错误，我将不胜感激。在开发的配置方面，我还有很多东西要学。谢谢。

Answer 1

我通过从 Tomcat 8 降级到 Tomcat 7 解决了这个问题。我不确定为什么会这样，但我现在可以看到 "Hello World".

Answer 2

您使用的 JSP 版本与 Tomcat 8 版本不兼容。看看这个：http://tomcat.apache.org/whichversion.html

   package com.abc.controller;
   import org.apache.log4j.Logger;
   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("/hello")
    public class HelloWorldController {
      Logger logger = Logger.getLogger("HelloWorldController"); 
       @RequestMapping(method=RequestMethod.GET)
     public ModelAndView helloController() {
      logger.info("inside Controller");
      String message = "Hello World";
      return new ModelAndView("HelloWorldPage", "message", message);
    }

这是我在上面发布的文件我成功部署了应用程序并打印了 Hello World 如果有人遇到任何问题，请完成此流程并生成 war 然后按照我的 pom.xml.if如果您收到 404 错误代码而不是再次重启您的 eclipse，它肯定会起作用。
