2. 目录结构

3. jdbc.properties配置文件

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/batis
jdbc.username=root
jdbc.password=123456

4. mybatis的配置文件

<?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>
    <!-- STDOUT:输出到控制台-->
    <setting name="logImpl" value="STDOUT_LOGGING"/>
  </settings>
</configuration>

3. 在Spring配置文件中，配置MyBatis

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

                           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
<!--  组件扫描 -->
