### 6、在resources.config.spring下创建文件applicationContext.xml ###

applicationContext.xml内容：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:aop="http://www.springframework.org/schema/aop"
           xmlns:tx="http://www.springframework.org/schema/tx"
           xmlns:p="http://www.springframework.org/schema/p"
           xmlns:util="http://www.springframework.org/schema/util"
           xmlns:jdbc="http://www.springframework.org/schema/jdbc"
           xmlns:cache="http://www.springframework.org/schema/cache"
           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/tx
           http://www.springframework.org/schema/tx/spring-tx.xsd
           http://www.springframework.org/schema/jdbc
           http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd
           http://www.springframework.org/schema/cache
           http://www.springframework.org/schema/context/spring-cache.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop.xsd
           http://www.springframework.org/schema/util
           http://www.springframework.org/schema/aop/spring-util.xsd
           ">
    
        
        <context:property-placeholder location="classpath:config/jdbc.properties"/>
    
        
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
            
            
            
            
            
            
            
            
    
            <property name="url" value="${jdbc.url}"/>
            
            <property name="username" value="${jdbc.username}"/>
            
            <property name="password" value="${jdbc.password}"/>
    
            
            <property name="initialSize" value="1"/>
            <property name="minIdle" value="1"/>
            <property name="maxActive" value="20"/>
    
            
            <property name="maxWait" value="60000"/>
    
            
            <property name="timeBetweenEvictionRunsMillis" value="60000"/>
    
            
            <property name="minEvictableIdleTimeMillis" value="300000"/>
    
            <property name="validationQuery" value="SELECT 'x'"/>
            <property name="testWhileIdle" value="true"/>
            <property name="testOnBorrow" value="false"/>
            <property name="testOnReturn" value="false"/>
    
            
            <property name="poolPreparedStatements" value="false"/>
            <property name="maxPoolPreparedStatementPerConnectionSize" value="20"/>
    
            
            <property name="filters" value="stat"/>
        </bean>
    
    
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" p:dataSource-ref="dataSource"
              p:configLocation="classpath:config/mybatis/mybatis-config.xml"
              p:mapperLocations="classpath:config/mybatis/mapper/*.xml"/>
    
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="com.aaa.ssm.dao"
              p:sqlSessionFactoryBeanName="sqlSessionFactory"/>
    
        
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
              p:dataSource-ref="dataSource"/>
    
    
        
    
        <aop:aspectj-autoproxy  expose-proxy="true"    proxy-target-class="true"/>
    
        
        <tx:annotation-driven transaction-manager="transactionManager"/>
    
        
        
        
        
    
    </beans>

### 7、创建config下创建jdbc.properties文件完成jdbc的配置 ###

jdbc.properties内容：（写你自己的数据库用户名和密码）

jdbc.driver=com.mysql.cj.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/aaa?serverTimezone=Asia/Shanghai
    jdbc.username=root
    jdbc.password=123456

### 8、在config.mybatis下编写mybatis-config.xml文件（设置log打印日志） ###

mybatis-config.xml文件内容：

<?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>
        <settings>
            <setting name="logImpl" value="log4j"/>
        </settings>
    </configuration>

### 9、在resources.config.spring下创建dispatcher-servlet.xml配置文件（这个dispatcher-servlet.xml配置文件就是所谓的springMVC配置文件吧？）（在这儿特别指出，视频中只给出了扫描controller包，没有） ###

dispatcher-servlet.xml文件内容：

<?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-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.0.xsd
           http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
    
        <mvc:annotation-driven/>
        <context:component-scan base-package="com.aaa.ssm.controller"/>
        
        <context:component-scan base-package="com.aaa.ssm.service"/>
        <context:annotation-config/>
    
        <mvc:resources mapping="/css/*" location="/static/css/"></mvc:resources>
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver2">
            <property name="suffix" value=".jsp"/>
            <property name="prefix" value="/views/"/>
        </bean>
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    </beans>

### 10、在webapp.statics目录下创建静态资源文件夹css，js，images ###

###  ###

### 11、在webapp.WEB-INF下创建web.xml（有的话删了重新写就可以） ###

web.xml内容：

<?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_4_0.xsd"
             version="4.0">
        
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:config/spring/applicationContext.xml</param-value>
        </context-param>
        
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
    
                   
    
    
    
    
    
    
    
    
    
    
    
    
        
        
        <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*:config/spring/dispatcher-servlet.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>
    
        
    </web-app>
