spring事务的使用一

下面是关于spring 事务的处理学习

一、在applicationContext中配置

      1、配置事务数据源

	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<!-- 
			<property name="initialSize" value="10" />
			<property name="maxActive" value="50" />
		-->
	</bean>

      2、事务管理器

	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
	</bean>

      3、加载事务管理器

	<bean id="baseTxService" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
		abstract="true">
		<property name="transactionManager" ref="transactionManager" />
		<property name="proxyTargetClass" value="true" />
		<property name="transactionAttributes">
			<props>
				<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
				<prop key="query*">PROPAGATION_REQUIRED,readOnly</prop>
				<prop key="save*">PROPAGATION_REQUIRED</prop>
				<prop key="delete*">PROPAGATION_REQUIRED</prop>
				<prop key="fetch*">PROPAGATION_REQUIRED</prop>
				<prop key="rank*">PROPAGATION_REQUIRED</prop>
			</props>
		</property>
	</bean>

      4、利用继承简化事务管理的配置

<bean id="userService" parent="baseTxService"> <property name="target"> 
  <bean class="com.bbs.sys.service.UserService" /> </property> </bean>

 二、事务配置在Service中的使用

package sty.serviceImpl; 

public class userService implements TicketService { 
private DataSource dataSource; 

public void insert() { 
boolean flag = true; 
try { 

jt.update("insert into user value(2,'yuna','032012')"); 
if(flag) { 
throw new Exception("my exception");//抛出异常 
} 
System.out.println("over"); 
} catch (Exception e) { 
System.out.println("exception"); 
e.printStackTrace(); 
} 

} 
} 

 这里是不会进行事务回滚的，因为，自己捕获抛出了异常
