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.
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
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.
expression="execution(* com.hp.empinfo.service.EmployeeDao.*(..))"/>
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.
4. AOP Proxy Factory Bean: It creates an AOP proxy factory bean that contains the business
interface and the implementation class as the target.
class = "org.springframework.aop.framework.ProxyFactoryBean">
