2022-07-07 15:39:00 【做一道光】
2.2搭建开发环境
2.2.1创建crm项目
使用IDEA创建Empty Project，作为项目的工作空间
2.2.2创建crm模块
创建maven类型的模块，作为开发工程
2.2.3为项目添加meaven依赖

2.2.4添加相关配置文件
(1)mybatis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：控制mybatis全局行为-->
<settings>
<!-- 设置mybatis输出日志-->
<setting name="logImpl" value="STDOUT_LOGGING"/>
</settings>
<!-- 设置别名,主要为了简化对于类名的指定-->
<typeAliases>
<package name="com.it.entity"/>
</typeAliases>
<!--sql映射文件的位置-->
<mappers>
<!-- name:是包名，这个包中的所有mapper.xml一次都能够加载
使用package的要求：
1.mapper文件名和dao接口名必须完全一样，包括大小写
2.mapping文件和dao接口必须在同一目录
-->
<package name="com.it.dao"/>
</mappers>
</configuration>
(2)配置数据连接和事务
