spring 事务管理和事务传播的配置

spring  事务管理的两种配置方法

1. xml配置

2. 注解

 

一、xml配置

<?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:p="http://www.springframework.org/schema/p"
	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/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:component-scan base-package="com.spring"></context:component-scan>

	<!-- 1，引入外部contextSchema命名空间； 2，导入外部配置文件 -->
	<context:property-placeholder location="classpath:./jdbc.properties" />
	
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close">
		<property name="driverClass" value="${jdbc.driverClassName}" />
		<property name="jdbcUrl" value="${jdbc.url}" />
		<property name="user" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>
	
	<!-- 创建spring NamedParameter JdbcTemplate -->
	<bean class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate" id="namedParameterJdbcTemplate">
		<constructor-arg name="dataSource" ref="dataSource"/>
	</bean>
	
	<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">
		<tx:attributes>
			<tx:method name="*"/>
		</tx:attributes>
	</tx:advice> 
	
	<!-- 配置事务切面  -->
	<aop:config>
		<aop:pointcut expression="execution(* com.spring.service.*.*(..))" id="serviceMethod"/>
		<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceMethod"/>
	</aop:config>
	</beans>

 这样在com.spring.service包及其子类包都被事务管理了， 可更改<tx:method name="*"/>，更合理支持事务传播。

 

二、注解方式

xml配置更改为：

<?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:p="http://www.springframework.org/schema/p"
	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/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:component-scan base-package="com.spring"></context:component-scan>

	<!-- 1，引入外部contextSchema命名空间； 2，导入外部配置文件 -->
	<context:property-placeholder location="classpath:./jdbc.properties" />
	
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close">
		<property name="driverClass" value="${jdbc.driverClassName}" />
		<property name="jdbcUrl" value="${jdbc.url}" />
		<property name="user" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>
	
	<!-- 创建spring NamedParameter JdbcTemplate -->
	<bean class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate" id="namedParameterJdbcTemplate">
		<constructor-arg name="dataSource" ref="dataSource"/>
	</bean>
	
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	
	<tx:annotation-driven transaction-manager="transactionManager"/>

</bean>

 并且要在支持事务管理的类或者方法上加注解：

@Transactional
