</web-app>

3. Spring context : dbconfig.properties + applicationContext.xml

jdbc.jdbcUrl = jdbc:mysql://localhost:3306/name?useUnicode=true&characterEncoding=UTF-8
jdbc.jdbcDriver = com.mysql.jdbc.Driver 
jdbc.jdbcUser = root
jdbc.jdbcPassword = password

<?xml version="1.0" encoding="UTF-8"?>

       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">

    <!-- 配置 Bean 注解扫描器 -->

</beans>

4. MyBatis : 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">

<!-- MyBatis 全局配置文件 -->
<configuration>

    <settings>
        <!-- 指定使用 LOG4J 输出日志 -->
        <setting name="logImpl" value="LOG4J"/>

    <!-- 开启注解扫描：use-default-filters="false" 默认全部扫描，此配置关闭默认设置 -->
    <context:component-scan base-package="com.name" use-default-filters="false">
        <!-- 只扫描控制器 -->
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 配置视图解析器，方便页面返回信息 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
