Spring中管理数据库事务的配置使用详解

一、使用xml进行配置

1、导入Spring框架需要的基础业务数据包

2、配置通知

配置Service层中的哪些方法需要使用到事务，一般开发使用组的形式，即如下

3、将通知织入目标

4、完整的applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context"
    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-4.2.xsd 
                            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd 
                            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd 
                            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd ">


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


    <!-- 事务核心管理器,封装了所有事务操作. 依赖于连接池 -->
<bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
    <property name="dataSource" ref="dataSource" ></property>
</bean>
<!-- 事务模板对象 -->
<bean name="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate" >
    <property name="transactionManager" ref="transactionManager" ></property>
</bean>

<!-- 配置事务通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager" >
    <tx:attributes>
        <!-- 以方法为单位,指定方法应用什么事务属性
            isolation:隔离级别
            propagation:传播行为
            read-only:是否只读
         -->
        <tx:method name="save*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false" />
        <tx:method name="persist*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false" />
        <tx:method name="update*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false" />
        <tx:method name="modify*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false" />
        <tx:method name="delete*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false" />
        <tx:method name="remove*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false" />
        <tx:method name="get*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="true" />
        <tx:method name="find*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="true" />
        <tx:method name="transferMoney" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false" />
    </tx:attributes>
</tx:advice>


<!-- 配置织入 -->
<aop:config  >
    <!-- 配置切点表达式 -->
    <aop:pointcut expression="execution(* com.onex.service.imp.*ServiceImp.*(..))" id="txPc"/>
    <!-- 配置切面 : 通知+切点
            advice-ref:通知的名称
            pointcut-ref:切点的名称
     -->
    <aop:advisor advice-ref="txAdvice" pointcut-ref="txPc" />
</aop:config>

    <!-- <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> 
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property> <property 
        name="jdbcUrl" value="jdbc:mysql:///hibernate"></property> <property name="password" 
        value="root"></property> <property name="user" value="root"></property> </bean> -->

    <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClass}"></property>
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
        <property name="password" value="${jdbc.password}"></property>
        <property name="user" value="${jdbc.user}"></property>
    </bean>

    <bean name="accountDao" class="com.onex.dao.imp.AccountDaoImp">
        <!-- <property name="jdbcTemplate" ref="jdbcTemplate"></property> -->
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <bean name="accountService" class="com.onex.service.imp.AccountServiceImp">
        <property name="accountDao" ref="accountDao"></property>
    </bean>

</beans>

二、使用注解配置

1、在xml中开启注解管理aop事务

2、在相应的Service层上进行使用注解

表示该方法配置的事务

表示该类下所有的方法都是用该事务（与方法不冲突）

3、完整的applicationContext.xml中的配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context"
    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-4.2.xsd 
                            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd 
                            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd 
                            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd ">


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

    <!-- <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> 
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property> <property 
        name="jdbcUrl" value="jdbc:mysql:///hibernate"></property> <property name="password" 
        value="root"></property> <property name="user" value="root"></property> </bean> -->
    <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClass}"></property>
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
        <property name="password" value="${jdbc.password}"></property>
        <property name="user" value="${jdbc.user}"></property>
    </bean>

<!-- 指定spring读取db.properties配置 -->
<context:property-placeholder location="classpath:db.properties"  />

<!-- 事务核心管理器,封装了所有事务操作. 依赖于连接池 -->
<bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
    <property name="dataSource" ref="dataSource" ></property>
</bean>
<!-- 事务模板对象 -->
<bean name="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate" >
    <property name="transactionManager" ref="transactionManager" ></property>
</bean>

<!-- 开启使用注解管理aop事务 -->
<tx:annotation-driven/>

    <bean name="accountDao" class="com.onex.dao.imp.AccountDaoImp">
        <!-- <property name="jdbcTemplate" ref="jdbcTemplate"></property> -->
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <bean name="accountService" class="com.onex.service.imp.AccountServiceImp">
        <property name="accountDao" ref="accountDao"></property>
    </bean>

</beans>
