传统的：
1 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
2 <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
3 <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:dev" />
4 <property name="username" value="kaktos" />
5 <property name="password" value="kaktos" />
6 </bean>
7
8 <bean id="txManager"
9 class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
10 <property name="dataSource" ref="dataSource" />
11 </bean>
12
13 <bean id="businessBean"
14 class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
15 <property name="transactionManager" ref="txManager" />
16 <property name="target" ref="businessBeanTarget" />
17 <property name="transactionAttributes">
18 <props>
19 <prop key="*">PROPAGATION_REQUIRED</prop>
20 </props>
21 </property>
22 </bean>
23
24 <bean id="businessBeanTarget" class="sample.spring.trans.BusinessBean">
25 <property name="dataSource" ref="dataSource" />
26 </bean>
这样做的弊端就是不得不为每个需要事务的bean做一次声明，如果所有的bean都基本上有一致的配置，这样就太繁琐啦。
下面是第二种方式：
1 <beans>
2 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
3 <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
4 <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:dev" />
5 <property name="username" value="kaktos" />
6 <property name="password" value="kaktos" />
7 </bean>
8
9 <bean id="txManager"
10 class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
11 <property name="dataSource" ref="dataSource" />
12 </bean>
13
14 <bean id="matchAllWithPropReq"
15 class="org.springframework.transaction.interceptor.MatchAlwaysTransactionAttributeSource">
16 <property name="transactionAttribute" value="PROPAGATION_REQUIRED" />
17 </bean>
18
19 <bean id="matchAllTxInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
20 <property name="transactionManager" ref="txManager" />
21 <property name="transactionAttributeSource" ref="matchAllWithPropReq" />
22 </bean>
23
24 <bean id="autoProxyCreator"
25 class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
26 <property name="interceptorNames">
27 <list>
28 <idref local="matchAllTxInterceptor" />
29 </list>
30 </property>
31 <property name="beanNames">
32 <list>
33 <idref local="businessBean" />
34 </list>
35 </property>
36 </bean>
37
38 <!-- my beans -->
39 <bean id="businessBean" class="sample.spring.trans.BusinessBean">
40 <property name="dataSource" ref="dataSource" />
41 </bean>
42 </beans>
BeanNameAutoProxyCreator会在applicationcontext初始化后自动为beanNames属性中的bean建立proxy。
