Modifying the applicationContext.xml File
Modify the applicationContext.xml file to include the following:
1. Transaction Manager: It contains the bean definition for the transaction manager class.
<bean id="txManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
NOTE: Because the EmpInfo application contains only JDBC operations,
org.springframework.jdbc.datasource.DataSourceTransactionManager is
used as the transaction manager class.
2. AOP Configurations: It contains reference to the transaction advisor and the class on which
the transaction advise will be applicable.
<aop:config>
<aop:pointcut id="empdaoOperation"
expression="execution(* com.hp.empinfo.service.EmployeeDao.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="empdaoOperation"/>
</aop:config>
3. Transaction Advice: It contains references to the transaction manager class and transactional
details of the getEmployeeDetail, insertEmployee and deleteEmployee methods
in the EmployeeDao.java class.
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
4. AOP Proxy Factory Bean: It creates an AOP proxy factory bean that contains the business
interface and the implementation class as the target.
<bean id = "iempdao"
class = "org.springframework.aop.framework.ProxyFactoryBean">
<property name = "proxyInterfaces">
