# 搭建一个maven工程 #

1、file—>new ------> maven project(或者maven module)—> create a simple project(skip archetype selection)

2、填写artifact：  
Group Id：com.atguigu  
Artifact Id： SpringMVC  
Packaging：war

3、发现项目出现了一个x  
解决：选择项目—> 点击右键 ----> 选择Properities，找到Project Facets----》 去掉Dynamic web module上的√，点击Apply，选中Dynamic web module的√  
\----》选择Further configuration available  
\----》 修改Content directory为 src/main/webapp

# 导入jar #

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

      <packaging>war</packaging>
      
       <properties>
    	  <atguigu.spring.version>4.0.0.RELEASE</atguigu.spring.version>
       </properties>
      
      	<dependencies>
      		<dependency>
    		    <groupId>org.springframework</groupId>
    		    <artifactId>spring-web</artifactId>

    		<dependency>

    			<version>${atguigu.spring.version}</version>
    		</dependency>
      	</dependencies>
    </project>

# 修改web.xml #

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
    
    
        
    	<servlet>
    		<servlet-name>springDispatcherServlet</servlet-name>
    		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    		<init-param>
    			<param-name>contextConfigLocation</param-name>

    	<filter-mapping>
    		<filter-name>CharacterEncodingFilter</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>
    </web-app>

# 配置springmvc.xml #

/SpringMVC/src/main/resources/spring-web-mvc.xml下

<?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"
    	xmlns:mvc="http://www.springframework.org/schema/mvc"
    	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-4.0.xsd
    		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
    
    	<context:component-scan base-package="com.atguigu.springmvc"></context:component-scan>
    
    	
    	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    		<property name="prefix" value="/WEB-INF/views/"></property>
    		<property name="suffix" value=".jsp"></property>
    	</bean>
    </beans>

# 编写测试代码 #

1、/SpringMVC/src/main/java/com/atguigu/springmvc/hello/HelloWorld.java下

package com.atguigu.springmvc.hello;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class HelloWorld {
    
    	@RequestMapping("/hello")
    	public  String Hello() {
    		System.out.println("------------");
    		return "success";
    	}
    }

2、/SpringMVC/src/main/webapp/WEB-INF/views/success.jsp：

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>Insert title here</title>
    </head>
    <body>
    	Hello World
    </body>
    </html>

3、运行：http://localhost:8080/SpringMVC/hello.html
