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/context/spring-context-3.0.xsd       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
