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"?>

       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="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
        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-->

    <bean id="templateResolver"
          class="org.thymeleaf.templateresolver.ServletContextTemplateResolver" >
        <property name="prefix" value="/WEB-INF/templates/" />
        <property name="suffix" value=".html" />
        <property name="characterEncoding" value="UTF-8" />
        <property name="templateMode" value="HTML5" />
    </bean>


    <bean id="templateEngine"
