在Intellij中設置Spring MVC Maven“ Hello World” Webapp

Question

我正在嘗試在Intellij中設置spring webapp。 我正在使用Maven管理依賴項和本地Tomcat Web服務器。 到目前為止，我已經使用Spring MVC模板創建了該項目。

我基本上遵循本教程，但是使用Intellij 13.1.6並使用Spring MVC模板： http ://alfasin.com/setting-up-spring-web-project-on-intellij-using-maven/

我認為這將使我能夠快速啟動並運行“ Hello World”應用程序。 但是，我遇到了500個無法解決的內部錯誤。

當我嘗試運行該應用程序時，通常會出現以下錯誤：

看似隨機，有時我會得到以下錯誤：

這是我的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">

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

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

</servlet>

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

這是我的mvc-dispatcher-servlet.xml文件：

<beans xmlns="http://www.springframework.org/schema/beans"

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

這是我的控制器：

package com.maynard.pipes;

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";
    }
}

這是我的Tomcat配置：

如果有人能指出我做錯了什么，我將不勝感激。 在開發的配置方面，我還有很多東西要學習。 謝謝。

Answer 1

您使用的JSP版本與Tomcat 8版本不兼容。 檢查一下： http : //tomcat.apache.org/whichversion.html

Answer 2

我已經通過從Tomcat 8降級到Tomcat 7來解決了這個問題。我不確定為什么這樣做，但是現在可以看到“ Hello World”了。

Answer 3

   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

這是我在上面發布的文件，我已成功部署了該應用程序並打印了Hello World，如果有人遇到任何問題，請按照以下流程操作並按照pom.xml進行操作，如果之后出現404錯誤代碼而不是重新啟動您的文件，日食再次確保工作。
