     <property name="driverClass" value="${jdbc.driver}"/>
     <property name="jdbcUrl" value="${jdbc.url}"/>
     <property name="user" value="${jdbc.username}"/>
     <property name="password" value="${jdbc.password}"/>
     
     <!-- c3p0连接池的私有属性 -->
     <property name="maxPoolSize" value="30"/>
     <property name="minPoolSize" value="10"/>
     <!-- 关闭连接后不自动commit -->
     <property name="autoCommitOnClose" value="false"/>
     <!-- 获取连接超时时间 -->
     <property name="checkoutTimeout" value="10000"/>
     <!-- 当获取连接失败重试次数 -->
     <property name="acquireRetryAttempts" value="2"/>
         </bean>
     
         <!-- 3.配置SqlSessionFactory对象 -->
         <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
     <!-- 注入数据库连接池 -->
     <property name="dataSource" ref="dataSource"/>
     <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
     <property name="configLocation" value="classpath:mybatis-config.xml"/>
         </bean>
     
         <!-- 4.配置扫描Dao接口包,动态实现Dao接口注入到spring容器中 -->
         <!--解释 : https://www.cnblogs.com/jpfss/p/7799806.html-->
         <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

     <!-- 给出需要扫描Dao接口包 -->
     <property name="basePackage" value="com.mvc.dao"/>
         </bean>
     
     </beans>

    2.编写spring-service.xml配置文件,Spring整合service层

     <?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">
     
         <!-- 扫描service相关的bean -->
         <context:component-scan base-package="com.mvc.service" />
     
         <!--BookServiceImpl注入到IOC容器中-->
         <bean id="BookServiceImpl" class="com.mvc.service.UserServiceImpl">
     <property name="userMapper" ref="userMapper"/>
         </bean>
     
         <!-- 配置事务管理器 -->
         <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
     <!-- 注入数据库连接池 -->
     <property name="dataSource" ref="dataSource" />
         </bean>
     
     </beans>

    MVC层

    1.web.xml

      <!--DispatcherServlet-->
         <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:applicationContext.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>
     
         <!--encodingFilter-->
         <filter>
             <filter-name>encodingFilter</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>encodingFilter</filter-name>
             <url-pattern>/*</url-pattern>
         </filter-mapping>
         
         <!--Session过期时间-->
         <session-config>
             <session-timeout>15</session-timeout>
         </session-config>

     

    2.编写spring-mvc.xml配置文件, Spring整合MVC层

     <?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
         https://www.springframework.org/schema/mvc/spring-mvc.xsd">
     
         <!-- 配置SpringMVC -->
         <!-- 1.开启SpringMVC注解驱动 -->
         <mvc:annotation-driven />
         <!-- 2.静态资源默认servlet配置-->
         <mvc:default-servlet-handler/>
     
         <!-- 3.配置jsp 显示ViewResolver视图解析器 -->
         <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
             <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
             <property name="prefix" value="/WEB-INF/jsp/" />
             <property name="suffix" value=".jsp" />
         </bean>
     
         <!-- 4.扫描web相关的bean -->
         <context:component-scan base-package="com.mvc.controller" />
     
     </beans>

    3.配置整合文件applicaitonContext.xml

     <?xml version="1.0" encoding="UTF-8"?>
     <beans xmlns="http://www.springframework.org/schema/beans"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://www.springframework.org/schema/beans
             http://www.springframework.org/schema/beans/spring-beans.xsd">
     
         <import resource="spring-dao.xml"/>
         <import resource="spring-service.xml"/>
         <import resource="spring-mvc.xml"/>
         
     </beans>
      <tx:advice id="txAdvice" transaction-manager="transactionManager">
            <tx:attributes>
                <tx:method name="add" propagation="REQUIRED"/>
                <tx:method name="delete" propagation="REQUIRED"/>
                <tx:method name="update" propagation="REQUIRED"/>
                <tx:method name="query" read-only="true"/>
                <tx:method name="*" propagation="REQUIRED"/>
            </tx:attributes>
        </tx:advice>
     
        <aop:config>
            <aop:pointcut id="txPointCut" expression="execution(* com.tedu.dao.*.*())"/>
            <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
        </aop:config>
