1： 先创建一个maven web  项目：

可以参照之前的文章：  用Maven 创建一个 简单的 JavaWeb 项目

创建好之后的目录是这样的;

2: 先配置maven  修改pom.xml

3: 修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee"

    </context-param>
    <context-param>
        <!-- 日志页面的刷新间隔 -->

        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 配置静态资源映射,防止静态资源被拦截后导致controller返回的页面的js,css失效   这是第一种方式  还有一个方式在spring-mvc.xml中 -->
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.js</url-pattern>
        <url-pattern>*.css</url-pattern>

    </servlet-mapping>

    </servlet-mapping>
    
    <!-- 设置session 存活时长  60 min  -->
    <session-config>
        <session-timeout>60</session-timeout>
    </session-config>
</web-app>

4: 根据web.xml 添加一些文件:

再添加文件之前先来一张添加好之后的项目架构:

下面是: application.xml

<?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/mvc

       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop.xsd 
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx.xsd
       ">
          <!-- 上面没有带上版本号 系统会自动匹配合适的 -->

    <!-- 采用注释的方式配置bean -->
    <context:annotation-config />
    <!-- 自动扫描注解 -->
    <context:component-scan base-package="com.etoak.mssm" />

    <!-- 因为是简单的maven Spring SpringMvc  项目 所以 也就没有配置 数据源之类的; -->

</beans>

下面是: sring-mvc.xml

<?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.xsd 
       http://www.springframework.org/schema/mvc 
       http://www.springframework.org/schema/mvc/spring-mvc.xsd" >
       <!-- 上面没有带上版本号 系统会自动匹配合适的 -->
       
       
    <!-- 开启注解模式驱动 -->
    <mvc:annotation-driven></mvc:annotation-driven>

    <!-- 自动扫描web包 ,将带有注解的类 纳入spring容器管理 -->
    <context:component-scan base-package="com.etoak.mss"/>
    
    <!-- 视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    
    <!-- 默认的注解映射的支持 -->
    <mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/plain;charset=utf-8</value>
                        <value>application/json;charset=utf-8</value>
                        <value>application/x-www-form-urlencoded</value>
                    </list>
                    <!-- 设置 这些是为了 IE 浏览器 ajax 请求返回 json时  变成下载 -->
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>    
    
    <!--配置静态资源映射,防止静态资源被拦截后导致controller返回的页面的js,css失效   这是第二种方式  还有一种方式在web.xml中 -->
    <!-- <mvc:resources location="/static/css/" mapping="/css/**"></mvc:resources>
    <mvc:resources location="/static/js/" mapping="/js/**"></mvc:resources>
    <mvc:resources location="/static/images/" mapping="/images/**"/> -->
</beans>

为了体现出spring mvc 的作用  写了两个jsp页面 (index.jsp 和 welcome.jsp);

其中 index.jsp 放置在webapp 目录下面 可以直接访问 ; welcome.jsp放置在 WEB-INF 目录下面 只能通过 controller 跳转来访问.

先来张图:

技术分享

下面是index.jsp的代码:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String welcomePagePath = basePath+"index/welcome";
%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Index Page</title>
</head>
<body>
    This is index page .
    <br/>
    <br/>
    <a href="http://www.mamicode.com/"> Click on me to go to welcome page . </a>
</body>
</html>

这是 welcome.jsp的代码

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Welcome Page </title>
</head>
<body>
    This is welcome page .
</body>
</html>

下面就是处理请求,控制跳转的controller了

package com.etoak.mss.welcome.controller;

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

@Controller
@RequestMapping(value="/index")
public class WelcomeController {


    @RequestMapping(value="/welcome",method=RequestMethod.GET)
    public String welcome(){
        System.out.println("进来了!");
        return "welcome";
    }
}

ok  至此 整个项目 已经搭建完成:

先进行两个Maven 操作:clean 和 install ;

然后再在tomcat 上运行;

是不是看到下面的页面?

控制台 也打印了

 好了 上面就是 maven  和 Spring  SpringMvc  的整合 ;

接下来 准备再写一个 maven  spring spring Mvc  mybatis 整合项目;
