前言
新建一个普通的Maven项目
基本目录结构

├── src #
│ ├── main #
│ │ └── java # java代码目录
│ │ └── resources # 配置文件目录, 存放下面Spring配置文件
│ ├── test # 单元测试目录
├── web # web目录
│ └── WEB-INF # web.xml 配置文件目录

1. Mybatis层编写
1、在 resources 目录下新建数据库配置文件 database.properties
?

jdbc.driver=com.mysql.jdbc.Driver
# 如果是使用 MySQL8.0+ 那么还需要增加一个时区的配置; serverTimezone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456
|
2、在 resources 目录下创建Mybatis配置文件 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>
<!--配置数据源, 交给Spring-->
<!--配置log-->
<settings>
<!--STDOUT_LOGGING: 标准的日志工厂实现-->
<setting name="logImpl" value="STDOUT_LOGGING"/>

<typeAliases>
<package name="com.pro.pojo"/>

<!--绑定Mapper-->
<mappers>
<mapper class="com.pro.dao.BooksMapper"/>
</mappers>
</configuration>

2. Spring层编写
1. Spring整合Mybatis
配置Spring整合MyBatis，这里数据源使用c3p0连接池；
编写Spring整合Mybatis的相关的配置文件；在 resources 目录下创建 spring-dao.xml
注意：这里要引入上面Mybatis层的两个配置文件，配置文件的名称不要写错

2. Spring整合service
将业务层的类注入到Spring中，在 resources 目录下创建 spring-service.xml

3. SpringMVC层编写
1. 编写web.xml
修改 WEB-INF 下的 web.xml 文件
这里引入Spring整合的配置文件 applicationContext.xml
