SpringMVC Hello(IDEA)

　　以前一想要学习Java相关知识的时候，就会认为.NET FrameWork的相关技术还没学个通透还夹生饭。现在感觉只会.NET有些单一，需要多掌握几种开发技术，尽管.NET还没达到精通。貌似Hello XXX是很多程序的入门惯例。网上搜的都不全，自己摸索着来一篇Hello Spring MVC 开启我的Java之旅...

　　开发工具IDEA 2017.1.2

　　环境JDK1.8\Tomcat8.5.3

　　项目机构

 

 

　　1.新建项目

 2.配置项目

3.src下新建HelloController控制器（属于页面控制器）

package com.cj.springmvc;

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(value="hello")
public class HelloController {
    @RequestMapping(method = RequestMethod.GET)
    public String printHello(ModelMap model) {
        model.addAttribute("message", "Hello Spring MVC Framework!");
        return "hello";
    }
}

4.WEB-INF下新建文件夹jsp，jsp文件夹内新建hello.jsp文件

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Hello World</title>
</head>
<body>
<h2>${message}</h2>
</body>
</html>

5.配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>



    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>helloweb</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>helloweb</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

6.配置helloweb-servlet.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.cj"/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

7.配置Tomcat，选择自己的Tomcat和JDK安装路径
