  <artifactId>jstl</artifactId>
  <version>1.2</version>
</dependency>

二、web.xml(web容器)

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
                             http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

    <!--spring mvc 容器启动-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- spring 容器启动-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--字符编码过滤器，放在最前-->
    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- restful 支持 -->
    <filter>
        <filter-name>HiddenHttpMethodFilter</filter-name>
        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>HiddenHttpMethodFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

三、spring-mvc.xml(springmvc容器)

<?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">
    <!-- 扫描控制器，springmvc容器维护-->
    <context:component-scan base-package="com.edu.controller"/>
    <!-- 支持requestmapping注解，jsr303-->
    <mvc:annotation-driven/>
    <!-- 访问静态资源 -->
    <mvc:resources mapping="/resources/**" location="/resources/"/>
    <!-- 视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
</beans>

四、db.properties

jdbc.JdbcUrl=jdbc:mysql://localhost:3306/mybatis?characterEncoding=UTF-8
jdbc.JdbcDriver=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=root

五、spring.xml(spring容器)

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

       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       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/cache 
                           http://www.springframework.org/schema/cache/spring-cache.xsd 
                           http://www.springframework.org/schema/tx 
                           http://www.springframework.org/schema/tx/spring-tx.xsd 
                           http://www.springframework.org/schema/aop 
                           http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!-- spring 容器扫描除 controller的bean进行维护-->
    <context:component-scan base-package="com.edu">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <context:property-placeholder location="classpath:db.properties"/>

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="jdbcUrl" value="${jdbc.JdbcUrl}"></property>
        <property name="driverClass" value="${jdbc.JdbcDriver}"></property>
        <property name="user" value="${jdbc.user}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>

    <!--sqlsessionfactory-->
    <bean class="org.mybatis.spring.SqlSessionFactoryBean">

    </aop:config>
</beans>

六、mybatis-config.xml
