在Intellij中设置Spring MVC Maven“ Hello World” Webapp

Question

I am trying to set up a spring webapp in Intellij. I am using Maven to manage dependencies and a local Tomcat webserver. So far I have created the project using the Spring MVC template.

I am basically following this tutorial, but with Intellij 13.1.6 and using the Spring MVC template: http://alfasin.com/setting-up-spring-web-project-on-intellij-using-maven/

I would assume that this would allow me to get a "Hello World" app up and running quickly. However, I am getting 500 internal errors that I am having trouble solving.

When I try to run the app I usually get this error:

Seemingly randomly, I will sometimes get this error instead:

This is my web.xml file:

<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">

<display-name>Spring MVC Application</display-name>

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

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

This is my mvc-dispatcher-servlet.xml file:

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/pages/"/>
    <property name="suffix" value=".jsp"/>
</bean>

This is my controller:

package com.maynard.pipes;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

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

If anyone can point out what I've gotten wrong I would appreciate it. I still have much to learn on the configuration side of development. Thanks.

Answer 1

The JSP version you using is not compatible with the Tomcat 8 version. Check this out: http://tomcat.apache.org/whichversion.html

Answer 2

我已经通过从Tomcat 8降级到Tomcat 7来解决了这个问题。我不确定为什么这样做，但是现在可以看到“ Hello World”了。

   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);
    }

Answer 9

这是我在上面发布的文件，我已成功部署了该应用程序并打印了Hello World，如果有人遇到任何问题，请按照以下流程操作并按照pom.xml进行操作，如果之后出现404错误代码而不是重新启动您的文件，日食再次确保工作。
