1. 配置mybatis配置文件
创建mybatis配置文件,一般命名为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>
<!--配置全局属性-->
<settings>
<!-- 使用jdbc的getGeneratedKeys获取数据库自增主键 -->
<setting name="useGeneratedKeys" value="true"/>
<!-- 使用别名替换列名 默认:true
select name as title from table
-->
<setting name="useColumnLabel" value="true"/>
<!-- 开启驼峰命名转换: Table(create_time) -> Bean(createTime) -->
<setting name="mapUnderscoreToCamelCase" value="true"/>
</settings>
</configuration>
2. 创建spring-dao.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:property-placeholder location="classpath:jdbc.properties" />
<!--数据库连接池-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="driverClassName" value="${jdbc.driver}" />
<property name="maxActive" value="10" />
<property name="minIdle" value="5" />
</bean>
<!--配置sqlSessionFactory-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:mybatis-config.xml" />
<property name="typeAliasesPackage" value="cn.mejhwu.mall.bean" />
</bean>
<!--配置扫描包,加载mapper代理对象-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
<property name="basePackage" value="cn.mejhwu.mall.dao" />
</bean>
</beans>
3. 配置spring-service.xml配置文件

xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="cn.mejhwu.mall.service" />
</beans>
4. 配置spring-web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd

http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<mvc:annotation-driven />
<context:component-scan base-package="cn.mejhwu.mall.controller" />
<!--资源映射-->
<mvc:resources mapping="/static/**" location="/WEB-INF/static/" />
<!--配置thymeleaf视图解析器-->
