一、在resources包下，分别建三个包：mybatis、properties、spring包

 

1.mybatis包下的配置文件

（1）SqlMapConfig.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>
	<plugins>
		<!-- com.github.pagehelper 为 PageHelper 类所在包名 -->
		<plugin interceptor="com.github.pagehelper.PageHelper">
			<!-- 设置数据库类型 Oracle,mysql,MariaDB,SQLite,Hsqldb,PostgreSQL 六种数据库-->
			<property name="dialect" value="mysql"/>
		</plugin>
	</plugins>
</configuration>

2.properties包下的配置文件

（1）db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/pinyougoudb?characterEncoding=utf-8

jdbc.password=admin

3.spring包下的配置文件

（1）applicationContext-dao.xml
