> 已经大三了，想到快要工作实习，在大二时做了一个android APP的项目，最近和同学一起做一个项目，指导老师让我们用Spring框架，记录我自己学习ssm框架完成crud的整个过程。

开发环境windows+idea2017.1.5

##### 1、新建一个maven项目 #####

首先点击 File - New Project - 选择maven ，并且在右面选择maven-archtype-webapp选项，如图所示

![这里写图片描述][SouthEast]

点击next后，出现填写GroupId和Artifactid，其中
    1. GroupId写com.***.项目
    2. Artifactid写你的项目名称
    
    然后一直next即可

##### 2.项目目录结构 #####

![这里写图片描述][SouthEast 1]

其中java目录是自己添加，且设置为Sources Root。方法：选中目录->右键->Make Directory as->Sources Root。

##### 3.配置文件 #####

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

*5.配置mybatis-config.xml*

<?xml version="1.0" encoding="UTF-8" ?>
    
    <!DOCTYPE configuration
            PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
            "http://mybatis.org/dtd/mybatis-3-config.dtd">
    
    <configuration>
        <settings>
            <setting name="mapUnderscoreToCamelCase" value="true" />
        </settings>
        <typeAliases>
            <package name="com.copasso.crud.bean"></package>
        </typeAliases>
        
        <plugins>
            <plugin interceptor="com.github.pagehelper.PageInterceptor">
                <property name="reasonable" value="true" />
            </plugin>
        </plugins>
    
    </configuration>

其中还要新建一个dbconfig.properties文件，crud替换为你的数据库名

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/crud?useUnicode=true&characterEncoding=utf-8&useSSL=false
    jdbc.driverClass=com.mysql.jdbc.Driver
    jdbc.user=root
    jdbc.password=admin

##### 4.最后的项目结构 #####
