基于xml配置案例：

<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
​
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/myword"></property>
        <property name="username" value="root"></property>
        <property name="password" value="123456"></property>
    </bean>
​
    <bean id="wordsService" class="com.mypro.service.impl.WordsServiceImpl"></bean>
    <bean id="wordsDao" class="com.mypro.dao.impl.WordsDaoImpl"></bean>
​
    <!-- 配置事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!-- 配置事务通知 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <!-- 配置事务属性 -->
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED" read-only="false"></tx:method>
            <tx:method name="select*" propagation="SUPPORTS" read-only="true"></tx:method>
        </tx:attributes>
    </tx:advice>
​
​
    <!-- 配置AOP -->
    <aop:config>
        <!-- 配置AOP通用切入点表达式 -->
        <aop:pointcut id="pt1" expression="execution(* com.mypro.service.impl.*.*(..))"/>
        <!-- 建立事务通知和切入点表达式的对应关系 -->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pt1"></aop:advisor>
    </aop:config>
​
</beans>

 

基于注解配置：

<bean id="realDataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="${database.driverClassName}" />
    <property name="url" value="${database.url}" />
    <property name="username" value="${database.username}" />
    <property name="password" value="${database.password}" />
    <property name="defaultAutoCommit" value="false" />
    <property name="maxTotal" value="${cp.maxActive}" />
    <property name="maxIdle" value="${cp.maxIdle}" />
    <property name="minIdle" value="${cp.minIdle}" />
    <property name="maxWaitMillis" value="${cp.maxWait}" />
  </bean>

  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="realDataSource" />
  </bean>
  
  <tx:annotation-driven />　　　　//此处默认寻找id为transactionManager的事务管理器




然后是在需要添加事务的类中使用@Transactional   配置propagation(传播特性)、rollbackfor（什么情况回滚）、isolation（隔离级别）
