Eclipse中建立Maven，点击File,选择new一个Maven项目html

勾选Create a simple ...java

以下，补充完整，mysql

Group Id 组织名web

Artifact Id 项目名称spring

Version 版本号sql

packaging 打包方式，当项目为Java项目时，打成Jar包；当项目为web项目时，打成war包；当项目为其余...数据库

项目建立完成，在src/main/webapp/WEB-INF 下，新建web.xmlexpress

在pom.xml中 Add Denpendency(添加jar包)，从本地仓库中获取须要的jar包（图中灰色是由于已经导入）apache

Maven 中SSM整合spring-mvc

　web.xml以下

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

    id="WebApp_ID" version="2.5">
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>

        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
    
<!-- 定义一个过滤器，解决项目中编码问题 -->
    <filter>
        <filter-name>characterEncoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <!-- 设置编码参数 -->
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <!--6其余地方关于编码的设置通通失效-->
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    <!-- 监听器，主要监听spring主配置文件，web文件最初开始执行 -->
    <context-param>
        <!--类org.springframework.web.context.context.ContextLoaderListener中的成员contextConfigLocation,存储须要监听的文件路径-->
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml,classpath:mybatis-spring.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>


    <!-- springmvc 在filter执行完毕后，执行servlet-->
    <servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <!--指在tomcat执行完毕后，servlet才开始执行-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

在“src/main/resource”下（这也是web.xml中classpath默认的路径），新建 spring-mvc.xml，spring-mybatis.xml,srping.xml文件

spring-mvc.xml以下

<?xml version="1.0" encoding="UTF-8"?>
