三：整合Mybatis

完整的项目如下

一：下载所需的jar包


<!--日志-->
<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.17</version>
</dependency>

<!--数据源-->
<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-dbcp2 -->
<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-dbcp2</artifactId>
  <version>2.1.1</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring -->
<dependency>
  <groupId>org.mybatis</groupId>
  <artifactId>mybatis-spring</artifactId>
  <version>1.3.2</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.mybatis/mybatis -->
<dependency>
  <groupId>org.mybatis</groupId>
  <artifactId>mybatis</artifactId>
  <version>3.4.6</version>
</dependency>
<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjweaver</artifactId>
  <version>1.8.4</version>
</dependency>

二：编写配置信息

在dispatcher-servlet.xml中填写配置信息

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       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/tx http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/context

       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
    <mvc:annotation-driven/>
    <mvc:default-servlet-handler/>

    <!--开启扫描-->
    <context:component-scan base-package="com.founderit"/>
    <context:annotation-config/>

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


    <!--DBCP数据库连接池-->
    <bean id="dataSource"
          class="org.apache.commons.dbcp2.BasicDataSource"
          destroy-method="close">
        <property name="driverClassName" value="${DRIVERCLASS}"/>
        <property name="url" value="${URL}"/>
        <property name="username" value="${USERNAME}"/>
        <property name="password" value="${PASSWORD}"/>
        <!--maxActive: 最大连接数量-->
        <property name="maxTotal" value="150"/>
        <!--minIdle: 最小空闲连接-->
        <property name="minIdle" value="5"/>
        <!--maxIdle: 最大空闲连接-->
        <property name="maxIdle" value="20"/>
        <!--initialSize: 初始化连接-->
        <property name="initialSize" value="30"/>
        <!--removeAbandonedTimeout: 超时时间(以秒数为单位)-->
        <property name="removeAbandonedTimeout" value="10"/>
    </bean>

    <!-- spring和MyBatis完美整合 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!-- 自动扫描mapping.xml文件 -->
        <property name="mapperLocations" value="classpath:com/founderit/mapper/*.xml"></property>
    </bean>

    <!-- DAO接口所在包名，Spring会自动查找其下的类 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.founderit.dao"/>
        <!--        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>-->
    </bean>
    <!-- (事务管理)transaction manager -->
    <bean id="transactionManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- 通知 -->

    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <!-- 传播行为 -->
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="create*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
            <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
            <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
        </tx:attributes>
    </tx:advice>
    <!-- 切面 -->
    <aop:config>
        <aop:advisor advice-ref="txAdvice"
                     pointcut="execution(* com.founderit.service.*.*(..))" />
    </aop:config>
</beans>

按完整项目，建立对应的类
