• 第2章搭建CRM项目开发环境（搭建开发环境）

    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

    项目的pom.xml文件

    1. <?xml version="1.0" encoding="UTF-8" ?>
    2. <!DOCTYPE configuration
    3.         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    4.         "http://mybatis.org/dtd/mybatis-3-config.dtd">

    6.     <!-- settings：控制mybatis全局行为-->
    7.     <settings>
    8.         <!--   设置mybatis输出日志-->
    9.         <setting name="logImpl" value="STDOUT_LOGGING"/>
    10.     </settings>
    11.     <!--    设置别名,主要为了简化对于类名的指定-->
    12.     <typeAliases>
    13.         <package name="com.it.entity"/>
    14.     </typeAliases>

    17.     <mappers>
    18.         <!--  name:是包名，这个包中的所有mapper.xml一次都能够加载
    19. 使用package的要求：
    20. 1.mapper文件名和dao接口名必须完全一样，包括大小写
    21. 2.mapping文件和dao接口必须在同一目录
    22. -->
