eclipse，maven

1.新建maven项目，选择webapp

2.在pom文件中添加以下内容  1.8是java版本 项目名称为demo

<dependencies>
    		<dependency>
    			<groupId>junit</groupId>
    			<artifactId>junit</artifactId>
    			<version>3.8.1</version>
    			<scope>test</scope>
    		</dependency>
    		<dependency>
    			<groupId>org.springframework</groupId>
    			<artifactId>spring-web</artifactId>
    			<version>4.1.2.RELEASE</version>
    		</dependency>
    		<dependency>
    			<groupId>org.springframework</groupId>
    			<artifactId>spring-webmvc</artifactId>
    			<version>4.1.2.RELEASE</version>
    		</dependency>
    		<dependency>
    			<groupId>javax.servlet</groupId>
    			<artifactId>javax.servlet-api</artifactId>
    			<version>3.1.0</version>
    		</dependency>
    	</dependencies>
    	<build>
    		<plugins>
    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-compiler-plugin</artifactId>
    				<version>2.3.2</version>
    				<configuration>
    					<source>1.8</source>
    					<target>1.8</target>
    				</configuration>
    			</plugin>
    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-war-plugin</artifactId>
    				<version>3.1.0</version>
    			</plugin>
    		</plugins>
    		<finalName>demo</finalName>
    	</build>

3.修改web.xml文件 配置名为demo的servlet

<?xml version="1.0" encoding="UTF-8"?>
    <web-app 
    	xmlns="http://java.sun.com/xml/ns/javaee" 
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    	xmlns:web="http://java.sun.com/xml/ns/javaee"
    	
    	id="WebApp_ID" version="3.0" metadata-complete="true">
    
      <display-name>displayname</display-name>
      
      <servlet>
        <servlet-name>demo</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
      </servlet>
      <servlet-mapping>
        <servlet-name>demo</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
    
    
    </web-app>

4.新建demo-servlet.xml文件  配置viewResolver 在本例中页面编译后的位置是/WEB\_INF/classes/views/ 如果出现找不到页面的情况

可以 在dos中，进入项目目录，mvn package 打包 查看页面在包中的位置

<?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"  
        xmlns:p="http://www.springframework.org/schema/p"  
        xsi:schemaLocation="http://www.springframework.org/schema/beans  
                http://www.springframework.org/schema/beans/spring-beans.xsd  
                http://www.springframework.org/schema/mvc  
                http://www.springframework.org/schema/mvc/spring-mvc.xsd  
                http://www.springframework.org/schema/context  
                http://www.springframework.org/schema/context/spring-context.xsd"  
        default-lazy-init="true">  
          
          
          
        <mvc:annotation-driven />  
          
        <context:component-scan base-package="com.my.demo" />  
    
        <bean id="viewResolver"
            class="org.springframework.web.servlet.view.InternalResourceViewResolver">
              
            <property name="prefix" value="/WEB-INF/classes/views/"></property>  
              
            <property name="suffix" value=".jsp"></property>  
        </bean>  
          
    </beans>

5.新建controller

package com.my.demo.web;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class HelloWorldController {
    	
    	@RequestMapping("/login")
    	public String loginFunction(){
    		return "login";
    	}
    
    }

6.在resources下，新建views文件夹。新建login.jsp文件

<%@ page contentType="text/html;charset=UTF-8" language="java"  pageEncoding="UTF-8"  %>
    <html>  
        <head>  
        <title>标题</title>  
      
        </head>   
        <body>  
        	 欢迎来到Springmvc
        </body>  
    </html>

7.tomcat添加当前项目 debug启动  如果出现404，查看tomcat的path是不是“demo”

http://localhost:8080/demo/login 访问页面

目录结构如下
